GLOBAL VOLCANISM: 5,883 Tremors in 1 Day at Krakatau Volcano!

Anak Krakatau volcano
monitoring post reported Saturday increasing volcanic tremors at the famous volcanic island, located in the Sunda Strait between the islands of Java and Sumatra.

Head of the volcano monitoring post in Pasauran, Serang, Banten, Anton S. Pambudi said that the tremors had reached 5,883 on Saturday evening. "Data recorded at a monitoring post on Oct. 8 shows that 5,883 tremors came from the volcano as compared to 5,543 and 5,204 in the previous days," an official at the Anak Krakatau volcano monitoring post in Cinangka, Serang, Banten, Anton S. Pambudi, said Saturday as quoted by Antara news agency. Despite increasing volcanic activity, the the Volcanology and Geological Disaster Mitigation Center (PVMBG) has yet to further raise the level of alert status of the volcano. "We maintain the alert status on Siaga, which means that we prohibit local residents or visitors from approaching the volcano up to two kilometers in radius," Anto said. The authorities have raised the status of Anak Krakatau, which is Indonesian for 'Child of Krakatoa', to alert, the third of four alert levels, on Sept. 30. The authorities have raised the status of Anak Krakatau, which is Indonesian for 'Child of Krakatoa', to alert, the third of four alert levels, on Sept. 30.

"We call the residents not to panic despite the frequent tremors. But, we tell them not to approach the volcano's 2-kilometer radius," he said. Meanwhile, residents living along the coast of Anyer admitted that they did not worry about the tremors. "My family and I felt no difference compared to the situation before the authorities raised the alert status," said Doni, a resident of Paku, Anyer. Anak Krakatau erupted briefly on Tuesday spewing ash and rock high into the air. The eruption was the biggest since January 2011 when ash was emitted more than 600 meters into the air, forcing the evacuation of tens of thousands of residents. Last year, the volcano also erupted on Oct. 29 forcing the authorities to raise the alert status of the volcano. The volcanic island exploded in 1883, killing approximately 40,000 people. - Asia One.

GEOLOGICAL UPHEAVAL: Tons of Massive Coastal Rocks of Cornish Cliff in Cornwall in the United Kingdom, Crashes Into Celtic Sea?!

A huge section of the Cornish Cliff cracked and collapsed into the sea. The dramatic moment was captured in the following report and video.

If you're going for a relaxing clifftop walk any time soon, look away now. This incredible rockfall - caused by coastal erosion - was caught on camera by walkers in Cornwall. What looks like tons and tons of rock crashed down into the water below taking out a chunk of land. Footage shows the dramatic collapse happened just seconds after a huge crack in the cliff appeared. Anyone standing on top or on the rocks below would have stood no chance. The video is believed to have been taken at a spot called Dead Man's Cove which juts out into the Celtic Sea near Redruth.

The rockfall is the second reported on the same stretch of the north Cornish coast recently. Last week 20 tons of rock crashed down onto a Newquay beach 20 miles away. It happened just yards from where two young girls were playing in the sand. Police and coastguards immediately cordoned off the area at Towan beach amid fears of further rock falls. Cornwall Council's maritime manager Andy Brigden told the Cornish Guardian: 'These things happen. 'We've had people out looking at it. My advice would be don't sit in front of cliffs, especially when there are signs saying "beware of falling rocks".' Mr Brigden added it was impossible to halt the erosion of the coast and warned more rock falls were inevitable. - Daily Mail.

GLOBAL VOLCANISM: Alaskan Volcano Lava Threatens Planes!

Lava has reached the edge of a crater in a volcano in Alaska's remote Aleutian Islands, indicating the mountain could explode and send up an ash cloud that could threaten aircraft.

The Alaska Volcano Observatory (AVO) says satellite images show lava at the edge of the crater rim of 5,675-foot Cleveland Mountain on uninhabited on Chuginadak Island, about 940 miles southwest of Anchorage. Volcano monitors say if the dome continues to grow, it could overflow the rim and increase the possibility of an explosion. The observatory says an eruption could send up an ash cloud 20,000 feet or more. The nearest village, Nikolski, is on another island about 50 miles east and has 18 permanent residents. The village was not considered in harm's way in previous eruptions of the volcano. - ABC News.
According to the Weekly Volcanic Activity Report from the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program:

AVO reported that during 27-28 September and 30 September-1 October thermal anomalies over Cleveland's summit lava dome were detected in satellite images and suggested that the lava dome continued to slowly grow. Clouds obscured views on 29 September and during 2-3 October. Elevated surface temperatures were detected by satellite in partly cloudy images acquired during 3-4 October. The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange. No current seismic information was available because Cleveland does not have a real-time seismic network. Geologic Summary. Symmetrical Mount Cleveland stratovolcano is situated at the western end of the uninhabited dumbbell-shaped Chuginadak Island in the east-central Aleutians. The 1,730-m-high stratovolcano is the highest of the Islands of Four Mountains group and is one of the most active in the Aleutians. Numerous large lava flows descend its flanks. It is possible that some 18th to 19th century eruptions attributed to Carlisle (a volcano located across the Carlisle Pass Strait to the NW) should be ascribed to Cleveland. In 1944 Cleveland produced the only known fatality from an Aleutian eruption. Recent eruptions from Mt. Cleveland have been characterized by short-lived explosive ash emissions, at times accompanied by lava fountaining and lava flows down the flanks.

EARTH CHANGES: Severe Fresh Water Shortage in the South Pacific!

Crops are wilting, schools have shut their bathrooms and government officials are bathing in lagoons because of a severe shortage of fresh water in a swath of the South Pacific.

The island groups of Tuvalu and Tokelau have declared emergencies, relying on bottled water and seeking more desalination machines. Parts of Samoa are starting to ration water. Supplies are precariously low after a severe lack of rain in a region where underground reserves have been fouled by saltwater from rising seas that scientists have linked to climate change. While nobody has gone thirsty yet, officials worry about the logistics of supplying everyone with enough water to survive and the potential health problems that might arise. And exactly how the islands will cope in the long term remains a question mark.

“We are praying that things will change,” Samoan-based official Jovilisi Suveinakama said. Six months of low rainfall have dried out the islands. Climate scientists say it’s part of a cyclical Pacific weather pattern known as La Nina — and they predict the coming months will bring no relief, with the pattern expected to continue. Rising sea levels are exacerbating the problem, as salt water seeps into underground supplies of fresh water that are drawn to the surface through wells. On the three main atolls that make up isolated Tokelau, the 1,400 residents ran out of fresh water altogether last week and are relying on a seven-day supply of bottled water that was sent Saturday from Samoa, Suveinakama said. - Washington Post.

EXTREME WEATHER: UK Braces for Ice-Age Temperatures of -20C!

Britain is just weeks away from being in the grip of temperatures as low as -20C, forecasters have predicted.

Parts of Britain already saw snow this week, with two inches falling in the Cairngorms in Scotland. The rest of Britain is being warned to brace itself for wintry conditions and falling snow from the beginning of November. And it looks like the colder weather is already on its way - as temperatures today plunged in certain areas to just 8C - a staggering 21.5C below last weekend's record highs - with the wind chill making it feel decidedly colder. In central London today readings of 13C were recorded, in Macduff, Aberdeenshire, the mercury plummeted to 8C, while Plymouth, in Devon, was comparatively basking in 16C of heat. The warning of freezing weather comes as a survey from council leaders reveals local authorities are stockpiling thousands of tonnes of extra road salt this year in anticipation of another white winter. James Madden, long-range forecaster for Exacta Weather, said: 'I expect the most frequent and heavy snowfalls to occur across many parts of the UK during November, December and January at present.
'I initially expect frequent and significant snowfalls across many northern regions and Scotland throughout this winter. Any earlier snowfall is likely to be more confined to northern and western parts of the UK, although large scale low pressure systems also offer the potential for significant snowfalls to many parts of the UK.  I also expect November, December, January and February to feature largely below-average temperatures across many parts of the UK, it is likely that temperature and snowfall records will be broken within this defined time frame.' Some shops are already planning ahead for the bad weather. Halfords has ordered in 10,000 plastic sledges in anticipation of the big freeze. Research by the Local Government Association (LGA), which represents more than 350 councils in England and Wales, shows on average local authorities aim to have 1,500 tonnes more salt at the ready to treat roads and pavements than they did at the start of October 2010. Each council spread about 3,900 tonnes of salt, on average, last year, while this year councils are armed with about 4,900 tonnes. In total, an estimated 1.4million tonnes of salt is expected to be stockpiled this year. Many authorities faced criticism last winter as the nation's motorists battled dangerous roads caused by freezing temperatures, many becoming stranded. - Daily Mail.
