According to INSIVUMEH, the source of the collapses is the continued supply of viscous lava that extrudes into the summit of the Caliente dome, and the collapse and pyroclastic flows affected its eastern side.

Ash fall occurred in areas to the west and southwest in up to 25 km distance, including the towns of Cuyotenango, San Francisco, Zunilito and Pueblo Nuevo.

Seismic activity, including tremor reflecting the degassing of the lava lake, fluctuates at moderate to high levels.


Pavlof (Alaska Peninsula, USA): Seismic activity at the volcano has continued to decrease over the past two weeks and no anomalous activity has been detected in satellite data since weakly elevated surface temperatures were seen on April 8.

AVO is therefore lowering the aviation color code to GREEN and the Volcano Alert Level to NORMAL.


Langila (New Britain, Papua New Guinea): Darwin VAAC reported ash emissions from the volcano that rose to 7,000 ft (2.1 km) altitude and drifted up to 100 km north.

Aviation color code is at orange.


Alaid (Northern Kuriles, Kuril Islands): Eruptive activity on the remote volcano continues; satellite images show fresh ash deposits and evidence a strong heat source from the crater.

This morning, VAAC Darwin reported a plume at approx. 7,000 ft (2.1 km) altitude extending 50 km to the NE, well visible on satellite images.


Nevados de Chillán (Chile):  New ash emissions occurred yesterday morning, generating a small plume that rose approx. 500 m.

According to Sernageomin, this activity is not caused directly by fresh magma, but related to disturbances of the shallow hydrothermal system which interacts with an underlying, probably only small body of magma.SERNAGEOMIN also reported a slight increase in earthquakes typical of internal fluid movements (LP- long period events) during the past weeks and that sporadic ash emissions are likely to continue.

The volcano's alert level remains at "yellow" and it is recommended to stay outside a radius of 2 km around the active craters


Popocatépetl (Central Mexico): Following Monday's large explosive activity (2 hours of lava fountaining), the volcano returned to be relatively calm, producing only steam emissions and no significant explosions.

Steam emission ("exhalation") from Popocatepetl volcano.

Bright glow remains visible from the summit, indicating that magma continues to rise and accumulate at the summit vent.


Suwanose-jima (Ryukyu Islands, Japan):  The strombolian-type activity from the volcano on the small island in southern Japan continues to be elevated.

Frequent explosions produce small to moderate ash plumes that rise to altitudes of 5-7,000 ft (1.5-2 km).

Constant glow is visible from the O-take crater at night.


Soufrière Hills (Montserrat): On the island of Montserrat, heavy rains have eroded and re-mobilized the eruptive ash deposits in the Belham Valley, creating lahars there and making of this a dangerous area.

The activity of the volcano Soufriere Hills, remains unchanged, characterized by a plume of gas blown northwards towards uninhabited areas. The alert level remains at 1.




Etna (Sicily, Italy): At Etna, ash emissions are noticed on the night of April 20 to 21, still visible the next morning at the northeast and new southeast craters.

 EtnaLive site states, based on the latest multidisciplinary INGV Catania report on the April 19th, that at the level of Bocca Nuova, the crater floor collapsed gradually, to produce the formation of a new crater in the fossa.

April 12, 2016 - GUATEMALA - The volcanic activity of the Fuego volcano is increasing in Guatemala.

The last loud eruption on April 12, 2016 was heard over an area of 15km, rocked the roof and windows of houses located 15 km from the volcanic peak and sent a column of ash and gases 4km in the air.

It's not only the Santa Maria volcano, but also the Fuego volcano that shows an enhanced explosive activity in Guatemala these days .

According to Insivumeh, the National Institute for Seismology, Vulcanology, Meteorology and Hydrology of Guatemala, the Fuego volcano heavily exploded four to 6 times on April 12, 2016 sending a column of ash 4800 meters above sea level.


WATCH: Here a timelapse video showing the explosions.

The explosion were accompanied by moderate to strong rumblings as well as ash falls in Panimache, Morelia, Sangre de Cristo, Santa Sofía, Chimaltenango.

Lava was ejected up to 200 m above the crater.

The eruptions produced a roaring noise similar to a jet engine that lasted 2 to 5 minutes and was heard over a broad radius of 30 km.

 WATCH: Here another video captured by a camera located at La Reunion Golf Resort, Guatemala about 7 km southeast of the summit of Fuego.

The resulting shock waves rocked the roof and windows of houses located 15 km from the volcanic peak.

This enhanced activity at Fuego is disturbing the local population.

Seismometers show that the magma is rising inside the crater, which may cause a major eruption in the next few days.


WATCH: And this major eruption could look like this one in January 2016 - Fiery and furious! .

GLOBAL VOLCANISM: The Latest Report Of Volcanic Eruptions, Activity, Unrest And Awakenings – March 26-29, 2016! [PHOTOS]

March 29, 2016 - EARTH - The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe.

Sakurajima (Kyushu, Japan): Over the past days, vulcanian-type explosions have again picked up in number and size, after only very few events during the first 3 weeks of March. Ash plumes rose to up to 10-12,000 ft (3-3.6 km) altitude.

The remarkable novelty is that most of the recent explosions occurred from the Minamidake crater, the volcano's old summit vent, and not from the Showa crater on its eastern flank, which had been (an almost exclusive) protagonist during the 10 years since 2006 until very recently.


Pavlof (Alaska Peninsula, USA): A new eruption started at the volcano abruptly Sunday (March 27) afternoon at 16:16 local time (00:18 UTC). An explosive eruption with lava fountaining produced an ash plume that quickly rose to approx. 20,000 ft elevation (6 km) and the Aviation Color code was raised to red.

Eruption of Pavlof on March 28, 2016 (Image: Almandmoss, Nahshon / Alaska Coast Guard / AVO)

The activity continued and reached its peak over the next 24 hours, when a sustained, continuous ash plume extended more than 700 km (400 miles) to the northeast over interior Alaska, with a maximum height of 37,000 ft (9 km) altitude.

Lava fountaining from the summit crater was observed throughout the night by mariners, pilots, and by residents in Cold Bay, located 37 miles (60 km) to the SW.

Volcanic mudflows (lahars), generated by rapidly melting ice and snow, are likely descending on the flanks of the volcano and could present a hazard in the local river valleys.

Alaska Volcano Observatory recorded continuous strong tremor accompanying the eruption. As of today (Tuesday morning), the eruption continues at much reduced intensity and the Aviation Color code has been lowered to ORANGE.


Santiaguito (Guatemala): Activity continues at the Caliente lava dome with little changes.

The volcano observatory reported strong degassing, some weak to moderate explosions with ash plumes rising up to approx. 900 m and constant block lava avalanches on the eastern and southeastern flanks of the lava dome.

The latter suggests that effusive activity has been elevated recently compared to during previous months.


Pacaya (Guatemala): Mild activity continues at the intra-crater cone of the Mackenney crater. INSIVUMEH reports a steam and gas plume rising 600 m and glow from lava visible at night.

Fuego (Guatemala): During the past week, activity at the volcano gradually increased into the 5th paroxysm in 2016, generating pulsating lava fountains, lava flows and possibly pyroclastic flows.

After the previous such episode in early March, the volcano had continued to produce its typical, persistent, but intermittent strombolian activity. The latter started to become more and more intense from around March 22, and became near-constant during March 24-25.

Lava fountains from Fuego during the night of 25-26 March 25-26, 2016

At least two lava flows of 1000 and 1700 m length formed on the upper western (Santa Teresa gully) and southeastern slope (Las Lajas ravine). Ash plumes rose to altitudes of approx. 5000 m and drifted up to approx. 160 km to the west over the Pacific Ocean.

After its latest paroxysm a few days ago, activity of the volcano has returned to normal levels with intermittent (one every few hours) weak to moderate-sized strombolian explosions.


Momotombo (Nicaragua): A slight increase in activity occurred last week between 23-26 March, when the volcano again produced some mild to moderate explosions, some of which were strong enough to send bombs to its upper outer slopes.

Moderately strong explosion at Momotombo on March 26.

During the past days, activity has again been calmer, although crater glow continues to tell the presence of fresh lava in the summit crater.

March 7, 2016 - EARTH - The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe.


Tungurahua (Ecuador): The volcano is in a phase of mild to moderate strombolian activity. Incandescent bombs are ejected to the upper slopes of the volcano, generating avalanches. Ash plumes rise up to a few km above the crater and drift mostly in westerly directions.

Apparently, the large vent-clearing explosion on 27 Feb has opened the conduit to allow a sustained slow rise of magma and more gradual release of gas pressure in small discrete explosions (= strombolian activity).

In its latest report, IGEPN published a series of remarkable photos taken during cloud-free periods at night.



Nevado del Ruiz (Colombia): An explosion occurred at the volcano this morning, producing an ash plume that rose 3000 m above the summit. The eruption was accompanied by Ash falls occurred later in several nearby towns to the NW including Chinchiná, Villamaría, Manizales and Palestine.

The regional La Nubia airport was closed today after noon.


Shiveluch (Kamchatka): The lava dome continues to be very active, generating frequent rockfalls and small glowing avalanches on the SW side as well as, more rarely, on the SE side as can be seen on today's time-lapse video.


WATCH: Time-lapse of Shiveluch.

A larger event might have taken place after dark, as Tokyo VAAC reported an ash plume to 18,000 ft (5.4 km) altitude this morning 08:20 UTC (17:20 local time in Kamchatka).



Copahue (Chile): The activity at the volcano, near-constant degassing with sometimes ash emissions, has decreased over the past weeks. Ash venting has become less frequent and intense, and the glow from E Agrio crater that had been visible at the crater disappeared.

Weak steam/ash plume from Copahue.

According to the Chilean scientists from SERNAGEOMIN who monitor the volcano, the current activity of the volcano is being caused by the interaction of a small volume of new magma under its highly active shallow hydrothermal system - none or little of this magma reaches the surface itself, but the heat transfer into the circulating fluids causes fragmentation by small explosions and the emission of gasses and particles (ash). This activity reflects in a continuous tremor signal of moderate intensity.

Scientists concluded that the new magma volume has been too small to greatly affect the internal balance in the hydrothermal system. Other geophysical parameters such as rate of degassing and deformation are mostly within normal levels of the volcano. It is therefore expected that the current activity continues in the coming weeks to months at fluctuating rates. This includes possible short-lived phases of more pronounced sporadic phreatic to strombolian explosions.




Chripoi (Kurile Islands, Russia): A new eruption might have taken place at the volcano this afternoon. Based on satellite imagery, Tokyo VAAC reported an ash plume to estimated 20,000 ft (6 km) altitude that drifted east.

Whether or not an eruption took place still needs to be confirmed.



Alaid (Northern Kuriles): A new eruption is occurring at the volcano, satellite images show. A pronounced steam plume with possible ash content can be seen drifting west from the volcano, at estimated 13,000 ft (4 km) altitude. In addition, NASA's MODIS and VIIRS sensors have been detecting an intense heat source from the volcano's summit lately.

Bromo (East Java, Indonesia): The latest eruptive cycle of the volcano might have ended. No more eruptions (explosions, ash emissions) have been observed during the past 2 weeks and seismic activity has returned to normal levels as well, our friend Oystein Andersen from Jakarta reported.

Tokyo VAAC raised the aviation color code to orange.


Suwanose-jima (Ryukyu Islands): The (probably) strombolian-type activity that had started a few days ago continues at the Otake crater and is visible as bright glow from neighboring islands.

Manam (Papua New Guinea): New activity has been reported from the volcano this morning. A pilot reported an ash plume at approx. 10,000 ft (3 km) altitude extending 50 km to the SE. A plume, along with a thermal signal, can also be seen on the latest satellite image.

You can find photos and more detailed reports of the latest eruption at his website.


Telica (Nicaragua): The volcano has remained mostly calm during the past 24 hours. Sporadic weak ash emissions occurred at night, but glow could no longer be seen from the crater.

Ash emission from Telica.

Masaya (Nicaragua): The activity of the lava lake in the Santiago crater has been increasing in the past week. In a recent bulletin, INETER mentions that the previously two ponds in two adjacent vents have now joined, probably as a result of erosion by the violently degassing and convective lava.

The following video taken on the 1st of March gives a good impression:


WATCH: Activity at the Masaya lake.

Nevados de Chillán (Central Chile): A small eruption occurred at the volcano again yesterday, the first activity since the mild explosive activity on 7 February. Starting around noon, the volcano began to emit a steam plume of variable intensity, sometimes mixed with ash. The activity took place at one of the new craters that had formed in early February.

Eruption of Nevados de Chillan volcano

According to SERNAGEOMIN, seismicity and other monitored parameters had shown little fluctuations during most of February, but then started to increase at the end of the month, possibly related to a slowly ascending body of magma. Yesterday's new activity is likely the result of this and could be a precursor of more activity in the near to medium future.


Bagana (Bougainville Island, Papua New Guinea): Based on Himawari-8 satellite data, Darwin VAAC reported an ash emission from the volcano at 7,000 ft (2.1 km) altitude last evening, creating a plume that drifted 100 km to the NE. Aviation color code is at Orange.


Kilauea (Hawai'i): The activity of the volcano remains essentially unchanged. Rising magma levels under the east rift zone briefly caused an overflow of lava that erupted from a spatter cone within the southern part of the Puʻu ʻŌʻō crater.

Thermal image of the lava overflow inside Kilauea's Pu'u 'O'o crater

This activity started around 8:15 a.m. local time yesterday (2 Mar), covered part of the crater floor and ceased at about 15:00 local time. No lava flowed beyond the crater. According to HVO, "this type of activity is not unusual for Puʻu ʻŌʻō, and does not reflect a significant change in the ongoing eruption".
At the summit caldera, rising magma levels temporarily brought the surface of the lava lake inside Halema'uma'u back in sight from the Jaggar Museum overlook in the early morning hours before receding.

Scattered surface flows remain active on the 'June 27th' flow field, all within about 6.0 km (4 mi) of Puʻu ʻŌʻō and do not currently threaten any nearby communities. Seismicity and deformation are within normal levels throughout the volcano.


Popocatépetl (Central Mexico): No significant changes in activity have occurred over the past weeks. Bright glow at the summit crater indicates that the lava dome in its inner crater continues to grow slowly.

Intermittent weak to moderate explosions (on average 2-3 per day) sometimes produce ash plumes that rise up to 1-2 km and rarely eject incandescent material outside the crater.


WATCH: Glow from Popocatepetl volcano.

Fuego (Guatemala): The volcano's activity started to drop again to normal levels (intermittent small explosions) yesterday evening - the most recent paroxysm has now ended.

View of Fuego volcano.

Barren Island (Indian Ocean): Weak eruptive activity continues at the summit vent of the remote and rarely directly observed volcano, satellite data indicates.

A thermal hot spot has been present regularly during recent weeks, and on cloud-free days, a steam-gas plume can often be seen drifting from the island that sometimes contains some ash.

What exactly the activity is like is difficult to say, but most likely is mild strombolian activity and/or the occasional presence of a (very small) lava lake in the summit crater.

March 2, 2016 - GUATEMALA - Guatemalan authorities issued a warning Wednesday as the country's Fuego volcano, located near the capital, spewed ash into the air.

A spokesman for the country's disaster response agency, David de Leon, said the 3,763-meter (12,346-foot) high volcano had entered a new eruptive phase with increasing explosive activity, prompting an orange alert indicating danger.

The volcano sent ash plumes billowing more than 2,000 meters (6,561.68 feet) above the crater; they then spread as far as 40 kilometers to the west, southwest and north, the spokesman said.

He added that rural communities surrounding the volcano, as well as the urban municipalities of San Pedro Yepocapa and Santa Lucia Cotzumalguapa de Escuintla, reported fine ash particles falling from the sky.

De Leon said his agency was in touch with local authorities and that so far no evacuations had been deemed necessary.

The Fuego volcano is located some 45 kilometers (30 miles) southwest of the capital Guatemala City.

Guatemala's Vulcanology Institute has instructed civil protection authorities to step up their vigilance and recommended precautionary measures for air traffic.

The Fuego volcano has long been active. A powerful eruption in February 2015 prompted an alert and the closure of Guatemala City's airport. - Yahoo.

GLOBAL VOLCANISM: The Latest Report Of Volcanic Eruptions, Activity, Unrest And Awakenings – March 1-2, 2016! [PHOTOS + VIDEO]

Explosion at Sinabung (Image: Andi / VolcanoDiscovery Indonesia)

March 2, 2016 - EARTH - The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe.


Sinabung (Sumatra, Indonesia): The activity of the volcano seems to have picked up.

Our correspondent Andi who's there on one of our Volcano Special tours, reported:

"Sinabung increases its activity after the big pyroclastic flow on February 26, which burned the remaining houses left from the previous damaged village (Simacem)...- this and the occurrence of highly hybrid tremors means there is deformation of the lava dome that grows continuously and increases the intensity of rock falls followed by pyroclastic flows."


Suwanose-jima (Ryukyu Islands): After a period of relative calm since last October, a new phase of strombolian activity occurred this morning at the volcano.


WATCH: Time-lapse video of Suwanose-jima.

Telica (Nicaragua): INETER and SINAPRED confirmed that a small amount of lava was erupted from a small new fissure into the crater of Telica during the night, as bright glow had suggested. A warning was issued not to approach the crater because of the risk of sudden explosions.

Shortly before dawn, weak ash emissions occurred from the crater, which since then has remained relatively calm, producing only a small intermittent steam/gas plume mixed with some light ash content.

Ash emission from Telica.

Telica's crater with bright glow from lava (?) about 40 minutes after the first signs of incandescence.

On March 1, a new eruption seems to be underway at the volcano. Bright glow has become visible from the crater since around midnight (local time).

This probably indicates that a new eruptive fissure is opening up there, possibly erupting lava onto the crater floor.


Fuego (Guatemala): The activity of the volcano continued to increase into its 4th paroxysm (called "eruption" by local press) of 2016. Lava effusion rate increased gradually and continued to feed the lava flow on the eastern side into the Las Lajas ravine, where it reached approx 600 m length yesterday and started to produce small pyroclastic flows (by collapse of parts of the flow on the steep slope).

Ash plume from Fuego.

Pulsating lava fountains at the summit vents generated an steam and ash plume that rose 2-3 km above the volcano, reaching altitudes of 17-20,000 ft(5.2 - 6 km). The plume drifted southwest for up to 20 km before dissipating.

Constant moderate to strong rumblings can be heard and felt in nearby areas.


Soputan (North-Sulawesi, Indonesia): The volcano has remained calm since its last eruption on February 6-7, but continues to show significant signs of unrest. Its alert level is being maintained at 3 on the Indonesian scale of 1-4.

Seismic activity at Soputan over the past year
(Red lines=explosion signals, GUGURAN=avalanche signals)

Visual activity during the past weeks consisted in degassing, producing a plume that rose 25-75 meters, and rock avalanches from the lava dome that indicate that magma supply continues into the dome at slow rate.

An exclusion zone of 4 km radius from the summit is in place and increased to 6.5 km towards the western sector. River beds draining from the volcano in particular should be avoided due to the elevated risk of lahars (mud flows) during rainfall.


Erta Ale (Danakil depression, Ethiopia): The level of the active lava lake in the volcano's southern pit crater of the summit caldera has sunk a bit again after its last overflow in mid January, but remains highly agitated. Our expedition leader Enku who was there with a small group from February 12-15 reported:

The lava lake of Erta Ale seen in late December 2015 (image: Enku Mulugheta)

"Erta Ale is going down again to 5- 7 Meters from the rim of the caldera, but the activity is getting very wild at this time and it was very hard to walk on the the recently crusted flow.

The last flow went in every direction from the crater and covered the whole rim with fresh crust of gaseous basaltic pahoehoe lava."


Momotombo (Nicaragua): Two moderately strong explosions occurred during the past 24 hours at the volcano, covering the upper slopes of the cone with fresh lava bombs and producing ash plumes that rose approx 2 km.

This followed a period of calmer activity that had lasted a few days.



Karymsky (Kamchatka): Two stronger explosions occurred this morning, producing ash plumes that rose to 13,000 and 17,000 ft (4.2 and 5.1 km) altitude and drifted NE, Tokyo VAAC reported.


Shiveluch (Kamchatka): The extrusive activity from the active dome has increased again recently. Near constant small to moderate glowing avalanches can be seen on the SW sector of the lava dome.

Incandescent rockfalls from Shiveluch

Some of them produce pyroclastic flows that travel a few km distance and produce ash plumes that rise up to 17,000 ft (5.1 km) altitude.


Sakurajima (Kyushu, Japan): The volcano is back at its typical style of activity of having intermittent (0-3 on average per day) small to moderate vulcanian explosions.

Eruption of Sakurajima volcano

Compared to most of 2013-15, Sakurajima's activity is relatively low, though.


Dukono (Halmahera): Intense ash emissions continue from the volcano. Darwin VAAC reported an ash plume at 8,000 ft (2.4 km) altitude extending 50 nautical miles to the NE yesterday.


Colima (Western Mexico): No significant changes have occurred recently at the volcano. The small lava dome continues to be active, while explosions have become small and rare.

Nevado del Ruiz (Colombia): The Manizales volcano observatory reported small ash emissions yesterday.

Tungurahua (Ecuador): Ash emissions have continued after the powerful vent-clearing explosion on Sunday (27 Feb). During brief periods when cloud cover lifted, a steam-and ash column was seen rising 1,500 meters above the crater and heading west.

Ash/steam emission from Tungurahua

Ash fall has been occurring in the sector of Mocha. Ground vibrations from the volcano could be felt in Manzano, Pillate, Patilahua and the Tungurahua Volcano Observatory.
