MASS FISH/BIRDS/ANIMAL DIE-OFF: Latest Incidents Across Asia - Hundreds Of Turtles Washing Ashore Dead Along East Coast Of India; TONS Of Fish Found Dead In Two Dams In Bandung Regency, Indonesia; 475,000 Birds Killed, Over 1.75 MILLION More To Be Killed Due To Outbreak Of Avian Flu In North Jeolla, South Korea; 10 TONS Of Fish Die Suddenly In Lake Maninau, West Sumatra, Indonesia; 10,000 Chickens Die Suddenly Due To Avian Flu In Kudat, Malaysia; And Hundreds Of Chickens Die Suddenly In Madiun County, Indonesia!

January 31, 2014 - ASIA -  The following constitutes the latest incidents of mass animal, bird and fish die-offs across Asia:

Hundreds Of Turtles Washing Ashore Dead Along East Coast Of India.

Hundreds of dead Olive Ridley Turtles are getting washed ashore along the Krishna district coastline of Bay of Bengal after getting trapped in the nets of fishermen.

The 115-km coast of the district serves as an ideal nesting ground for turtles. The dead turtles can be found in large numbers between Gilakaladindi Harbour and Manginapudi.
Unsafe practices

Unfriendly fishing practices are posing a major threat to Olive Ridley Turtles, which are classified as ‘vulnerable’ according to the International Union for Conservation of Nature and Natural Resources.

Around 250 boats, including 150 small engine boats, are operating from Gilakaladindi harbour and not even 10 per cent of them are equipped with Turtle Excluder Device (TED), despite repeated appeals by the authorities.

The TED allows the turtle that get trapped in the fishing net to escape safely.

Appeals to use the TED is falling on deaf ears of boat operators, leading to sharp rise in death toll of turtles.
No data

The Fisheries Department officials are not bothered about turtles and never insisted on use of TED by the boat operators, operating from Gilakaladindi harbour.

When asked about the number of boats equipped with TED, Harbour Fisheries Development Officer B. Raj Kumar told The Hindu that the department had no data and did not moot the issue with fishermen till date. Many boat operators said that they were releasing the turtles into sea when they were found in their nets .
Rookeries

The Wildlife Management Division, Eluru, in support of Yanadi tribal people set up four rookeries for the conservation of the turtles at Jinakapalem, Sangameswaram, Lighthouse area and Eelachetladibba, which is heart of the Krishna Wildlife Sanctuary, in Krishna district. - The Hindu.


TONS Of Fish Found Dead In Two Dams In Bandung Regency, Indonesia.
Tons of fish cultivated at the Cirata and Saguling dams in West Bandung regency, West Java, died due to the impacts of extreme weather in the regency over the last few days.

“The deaths [of the fish], which were sparked by the absence of sunlight, caused fish farmers in the Cirata and Saguling dams to suffer losses estimated at billions of rupiah,” Sundaya, a representative of the local fish farming association, said on Monday as quoted by Antara.

He added that the lack of sunlight reduced the oxygen content in water, making it difficult for the fish to breathe, leading them to die. “Additionally, the high intensity of rainfall caused water from the bottom of dams, containing sediment and mud and the remains of fish food, to rise to the surface,” said Sundaya.

That, according to him, resulted in the creation of toxic conditions in which the fish could not survive for long, even types of fish that have the power to survive in various climate conditions. “For example, the fish of the tilapia species died because of [these conditions], even though they are classified as strong fish,” he said.

It was also feared that the extreme weather could spark virus attacks. “It’s difficult to detect infections from viruses, which usually attack the fish’s gills,” Sundaya said.

His association therefore demanded support from the local government to help farmers overcome the impacts of the extreme weather. - The Jakarta Post.


475,000 Birds Killed, 1.75 MILLION More To Be Killed Due To Outbreak Of Avian Flu In North Jeolla, South Korea.
The government is considering imposing a lockdown at all poultry farms throughout the country as avian influenza was showing signs of further spreading, officials said Sunday.

A nationwide lockdown, if issued, will prohibit the movement of any poultry, workers or vehicles from farms for 48 hours. Such a move can be extended once for another 48 hours.

Such a move will create what health authorities here have called a "window of opportunity" to sterilize all poultry farms at the same time and thus prevent a further spread of the disease.

The consideration for such a move apparently comes as the animal disease is fast spreading to surrounding areas from Gochang in North Jeolla Province, where the first outbreak of AI was confirmed Jan. 17.

The government had imposed a 48-hour lockdown at all poultry farms in Gochang soon after the first outbreak of AI was confirmed.

The number of confirmed AI cases has since reached 18 with the highly pathogenic H5N8 strain of the virus confirmed in the latest case at a chicken farm in Buyeo, South Chungcheong Province on Saturday.

A new suspected case was reported earlier in the day at a duck farm in Cheonnan, located only some 80 kilometers south of Seoul, the Ministry of Agriculture, Food and Rural Affairs said in a press release.

Tests were under way in an additional 21 suspected cases as of Sunday.

Some 470,000 birds, mostly ducks, have been slaughtered so far.

Over 1.74 million others are set to be culled as the government has decided to also destroy chickens at all farms within 3 kilometers from affected farms after it confirmed the first outbreak of bird flu in chickens Saturday. - The Korea Herald.


10 TONS Of Fish Die Suddenly In Lake Maninau, West Sumatra, Indonesia.
About 10 tons of fish types of goldfish and tilapia in floating cages Maninjau, Agam regency, West Sumatra (West Sumatra), died suddenly due to high winds that hit the area.

Head of Maritime Affairs and Fisheries (DKP) Agam, Ermanto in Lubukbasung on Wednesday said the death of fish due to high winds that occurred a few days ago.

"The wind blows the water resulted in a reversal of the lake bottom to the water surface, so that the air in the bottom of the lake into a vacuum," he said.

He said dozens of tonnes of dead fish is the highest in the region Bayua and lascivious.

"This fish is dead since a few days ago in some floating net cages owned by farmers," said Ermanto.

As a result of this incident, the farmers suffered a loss of about Rp260 million, due to the price of fish in the market around Rp26.000 per kilogram.

To overcome this, Ermanto said, farmers are encouraged to stop stocking and immediate early harvest so that the other fish do not die.

Then, turn on the oxygen pump that has been given to the fishermen Agam DKP by 30 units in 2013, stop feeding for a while and others.

Previously, DKP Agam has given a circular to farmers to reduce seeding in August 2013 until January 2014, because at that time extreme weather that resulted in water rising to the surface and tubo Balerang.

"This circular every year we provide to the public with the aim that the farmers do not experience substantial losses. Yet people ignore these calls," he said.

He said, KJA fish deaths in Lake Maninjau reduced in each year, as many as 15,000 tons in 2008, then 2009 was 15,000 tons, 500 tons in 2010.

In 2011 as much as 500 tons, and 300 tons in 2012 and 2013 dropped to eight tons.

A farmer in floating cages Bayau, Amin, said he suffered a loss of tens of millions of dollars.

"Average dead fish ready for harvest. Myself pick two units of fish cages almost died. Cages can be harvested one ton of fish to reach a size of 8x10 meter cages," he said.

He said at present there are about Maninjau 16.000an floating net cages. Each farmer has about 4-10 cages. - Antara News. [Antara News]


10,000 Chickens Die Suddenly Due To Avian Flu In Kudat, Malaysia.
A total of 10,000 chickens died suddenly in some cage farm in the hamlet Gebot, Muktisari Village, District Cipaku, Kudat District during the last three days. Locals fret for fear of causing death allegedly by the H5N1 virus or bird flu.

One of the cattle owner, you Suhanda say, chicken livestock deaths have occurred during the three days. Each chicken flocks are dead, can reach thousands of head simultaneously.

"Death does not know what the cause is. Fact been found in dead chickens in the thousands tails. There is a cage running out at once," you clearly when questioned on Thursday (23/01/2014).

According to you, the symptoms of chicken that died initially as fever. A few hours later, the chickens were found dead. Almost ten cages total contents of 10,000 laying hens all died. "Laying hens that died when priced I could reach hundreds of millions of dollars," he said.

Meanwhile, some officials of the Animal Husbandry Department Kudat, immediately took some samples of the chickens that died suddenly. Starting from dirt, saliva, and eye examinations chicken.

"Samples will be analyzed in the laboratory. Currently we can not conclude whether or not the bird flu positive. Indeed, if there are symptoms with the sudden death of chickens simultaneously," explains Wasdi, Chief District Veterinary Office Kudat.

In addition to sampling, Wasdi said, it also gives the vaccine to the farm cages. The move was done so that the spread of the virus is not widespread. In fact, some of the workers at the farm was required so that the spread of the virus sterilization is not transmissible to humans.

"In addition to spraying the vaccine, we also conduct sterilization to humans. If the result is still waiting for the lab," he said.

This incident alarmed some other chicken farmers and local residents. Moreover, the spread of this dangerous virus can be deadly to humans. - Kompas. [Translated]

Hundreds of chickens owned by residents in the village Glonggong, Candimulyo, and Kradinan, Madiun, East Java, died suddenly discovered that allegedly caused the bird flu virus.

"I was shocked, as was already seen many dead. Approximately chicken types Bangkok more than 25 dead tail," said Jauhari, Glonggong Village residents, District Dolopo Wednesday.

According to him, dozens of chickens that died this tail has a characteristic blue head. In fact, the day before the condition of the pet chicken is relatively healthy.

Meanwhile, the condition of the other chickens are still alive is equally alarming. Comb chickens bluish, swollen eyes, and beak out of mucus mixed with blood. The disease is also known to attack other chickens belonging to her neighbors.

Jauhari claimed loss because the rooster kind Bangkoknya worth millions of dollars. However, he could not do much and the chickens must be willing to be destroyed by burning.

The same thing is expressed by villagers Sukemi Kradinan. Since the last three days, dozens of his chickens and other citizens, died suddenly every day.

Residents crowded-rama burn the chicken carcass so as not to infect other chickens are still healthy.

"We also have to report to the relevant agencies for immediate action from the bird flu disease," said Sukemi.

Meanwhile, Mantri Animal Husbandry and Fisheries Madison County Supeno said it could not confirm whether the hundreds of chickens died from bird flu virus attacks. That's because it is still awaiting the results of laboratory tests.

"To ascertain the cause of death of chickens, we have taken samples and sent to the laboratory. Still waiting for the result," said Supeno.

Besides burning infected chicken carcasses, it also asked the breeder chickens, ducks, and birds in the area to clean pet cages regularly.

Relevant government officers also spraying disinfectant on chicken coops and duck's in a number of locations in order to prevent bird flu or H5N1 virus in the local area.

As for the poultry population in accordance with the Department of Animal Husbandry and Fisheries records of local, free-range chicken reaches 1.5 million birds, 200 thousand chickens laying hens, broiler 400 thousand chickens, ducks and 70,000 of the tail. - Antara News. [Translated]

The side of a hill in Agam, west Sumatra, slid away on Sunday, wiping out homes, rice paddies and an orchard.  Government news wire Antara has put the economic damage at $800,000 and says rescue efforts have been hampered by poor access to the area.  With a small road being the only way to get to in, heavy equipment has not been able to reach the region to help dig for more victims. Police, military and rescue workers are searching with sniffer dogs.  Meanwhile, disaster authorities are hoping a massive cloud-seeding operation will prevent more major flooding in the capital, Jakarta. 

The cloud-seeding operation involves scattering salt in heavy rain clouds to get them to dump water on the ocean before they reach the capital and areas upstream.  Sutopo Purwo Negroho from the National Disaster Management Centre says the operation is aimed at avoiding the record-breaking flood which was forecast to hit by now.  He says he is not sure whether the same technique would work in Australia, as weather patterns are different, but an assessment could be done. - ABC News.

Landslide Causes Mini-Tsunami On Chinese River.
A van was hit by a wave of water created by a landslide Friday in central China's Hubei Province, leaving two people injured and damaging the Zhaojun Bridge, which temporarily suspended traffic. The van was driving down the middle of the Zhaojun Bridge at around 10:00 when strong wave pushed the van back about one meter. It was fortunate that no one on the van itself was injured, and that the two people crossing in the bridge were not injured seriously. "I was driving when I saw the rocks falling ahead. Then my van was pushed about one meter back by the splash. It was like the earthquake, and tsunami," said Liu Maoqing, the van's driver. The mountain of the landslide itself was 500 meters away from the Zhaojun Bridge, and the volume of the rocks that fell was more than 10,000 cubic meters. According to the reconnaissance by technical personnel of local Land and Resources Bureau, the landslide was caused by long-term physical weathering. The traffic on Zhaojun Bridge has resumed. - Emirates 24/7.

MONUMENTAL EARTH CHANGES: Indonesia Quake Break Records as Risks Grow For Aceh - A Once in 2,000 Years Event; Largest Strike-Slip Tremor Ever; Exceptionally Large and Rare Event; Second Biggest Aftershock Ever;...!

The powerful undersea earthquake off the Indonesian island of Sumatra this week was A ONCE IN 2,000 YEARS EVENT, and although it resulted in only a few deaths, it increases the risks of a killer quake in the region, a leading seismologist said.

Wednesday's 8.6 magnitude quake and a powerful aftershock were "strike-slip" quakes and THE LARGEST OF THAT TYPE EVER RECORDED. "It's a really AN EXCEPTIONALLY LARGE AND RARE EVENT. Besides it being the biggest strike-slip earthquake ever recorded, THE AFTERSHOCK IS THE SECOND BIGGEST as far as we can tell." Strike-slip quakes involve the horizontal movement of colliding earth plates, and are typically less powerful than those where there is vertical movement. They are also less likely to trigger big tsunamis, or tidal waves. Sumatra, the westernmost island in the sprawling Indonesian archipelago, has a history of powerful quakes and tsunamis, most triggered by an offshore zone along its entire length, where the Indian-Australian tectonic plate is forced under the Eurasian plate. This creates a deep ocean trench as one plate slides under the other at a rate of several centimeters a year. In this zone, called the Sunda megathrust, stress builds up when the subducting Indian-Australian plate bends the Eurasian plate like a spring board as it moves down into the Earth's crust. Eventually enough stress builds up that the edge of Eurasian plate suddenly jolts upward, triggering an earthquake. The sudden uplift of the seafloor and huge pulse of seawater triggers a tsunami. Over the centuries, repeated magnitude 8 and 9 quakes have struck along portions of the megathrust zone off the coast of Sumatra, flattening towns and killing thousands of people. Wednesday's event was different, because it occurred further west from the megathrust zone in a fault that runs north-south. This strike-slip fault involved a sudden horizontal movement of the Indian and Australian plates along hundreds of kilometers, preliminary data suggest. The Indian plate and Australian plate are moving relative to each other horizontally at about 1 cm a year.

"If all of that ... is taken up on this one fault and if you make some crude calculations about how much slip occurred during this earthquake, say 20 meters. It means that THIS EARTHQUAKE SHOULDN'T HAPPEN MORE THAN ONCE EVERY 2,000 YEARS." Wednesday's quake caused few casualties and triggered very small waves, despite its magnitude. But the sting in the tale is that it likely to have INCREASED STRESS ON THE PLATE BOUNDARIES NEAR ACEH, INCREASING THE RISKS OF ANOTHER MAJOR EARTHQUAKE IN THE SAME AREA AS THE 2004 DISASTER. In addition, research published in 2010 showed that the 2004 Aceh quake only relieved about half the stress that has built up over the centuries along a 400 km portion of the megathrust faultline. That makes another major quake in the area a matter of time. Adding to concerns, further south along another 700 km portion of the megathrust fault under the Mentawai islands, separate 2008 research said so much stress was building up on this section that one or more major quakes were likely within years. The Mentawai islands, a popular surfing destination, are a chain of about 70 islands off the western coast of Sumatra. They face the city of Padang on Sumatra, home to about one million people and likely to be in the path of any tsunami that is triggered. "I am very confident that we are very likely to have within the next few decades to have this great Mentawai earthquake that will have a magnitude at least as big as yesterday's." And when it does, history shows there will be more than one quake within a few years. A magnitude 8.4 quake in 2007 that struck this part of the megathrust relieved only a small portion of the pent-up pressure. The last time it ruptured was a magnitude 9 quake in 1833 and an 8.4 quake in 1797. "We've had so many big earthquakes around in Sumatra in the past few years that it seems like an awful lot of the faults around there seem ready to go." - Chicago Tribune.

SEISMIC MYSTERY: Geological Anomalies - "Odd Duck" Indonesia Quake Surprises Scientists?!

A magnitude-8.6 earthquake off Indonesia occurred along a strike-slip fault line similar to California's San Andreas Fault. Scientists say it's rare for strike-slip quakes, in which blocks of rocks slide horizontally past each other, to be this large. Wednesday's quake was followed by a magnitude-8.2 aftershock. Both were strike-slip quakes.

The massive earthquake off Indonesia surprised scientists: Usually this type of jolt isn't this powerful.  The biggest earthquakes tend to occur in subduction zones where one plate of the Earth's crust dives under another. This grind produced the 2004 magnitude-9.1 Indian Ocean disaster and the magnitude-9 Japan quake last year.  Wednesday's magnitude-8.6 occurred along a strike-slip fault line similar to California's San Andreas Fault. Scientists say it's rare for strike-slip quakes, in which blocks of rocks slide horizontally past each other, to be this large.  "It's clearly a bit of an odd duck," said seismologist Susan Hough of the U.S. Geological Survey in Pasadena, Calif.  As one of the world's most seismically active places, Indonesia is located on the Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin. Pressure builds up in the rocks over time and is eventually released in an earthquake. 

Wednesday's quake was followed by a magnitude-8.2 aftershock. Both were strike-slip quakes.  "A week ago, we wouldn't have thought we could have a strike-slip earthquake of this size. This is very, very large," said Kevin Furlong, a professor of geosciences at Penn State University.  So large, in fact, that the main shock went into the history books. Record-keeping by the USGS National Earthquake Information Center ranks Wednesday's shaker as the 11th largest since 1900. It's probably the largest strike-slip event though there's debate about whether a similar-sized Tibet quake in 1950 was the same kind.  A preliminary analysis indicates one side of the fault lurched 70 feet past the other -- a major reason for the quake's size. By contrast, during the 1906 magnitude-7.8 San Francisco earthquake along the San Andreas -- perhaps the best known strike-slip event -- the ground shifted 15 feet.  The Sumatra coast has been rattled by three strong strike-slip quakes since 2004, but Wednesday's was the largest. - Sci-Tech Today.

PLANETARY TREMORS: Massive 8.7 Magnitude Quake Rocks Indonesia's Sumatra Island - Tsunami Warning Across the Indian Ocean! UPDATE: 6.0 & 8.2 Magnitude Aftershocks Rattles Banda Aceh!

A massive earthquake has struck off Indonesia's Sumatra island, US and Indonesian monitors report, prompting a tsunami alert across the Indian Ocean.  The quake's magnitude was 8.7, according to a revised measurement from the US Geological Survey, and it struck 431 kilometres off the Indonesian city of Banda Aceh, on the island of Sumatra, on Wednesday at 2.38pm (1838 AEST) and at a depth of 33 kilometres.

The US Geological Survey initially reported it as an 8.9-magnitude quake. Indonesian authorities measured the tremor at 8.5.  The latest tremor was felt as far afield as Thailand and southern India.  According to the Joint Australian Tsunami Warning Centre, there was no tsunami threat to the Australian mainland, islands or territories.  There were no immediate reports of damage or casualties, said Prihyadi, an official at the Indonesian Meteorology, Geophysics and Climatology Agency.  "We have issued tsunami warnings for Aceh, North Sumatra and West Sumatra," said Prihyadi, who like many Indonesians uses only one name.  But residents across Sumatra fled their homes in panic, local media reported.  Residents in Banda Aceh reported the ground shaking violently.  "People are in a panic, and there are traffic jams everywhere in Banda Aceh," local Metro TV reported.  "There is potential for a tsunami to hit five provinces in the region - Aceh, North Sumatra, West Sumatra, Bengkulu and Lampung," said Marzuki, an analyst at Indonesia's Geophysics and Meteorology agency.  A tsunami watch was issued for India, the Seychelles, Somalia, Oman and South Africa as well. 

The Indian National Centre for Ocean Information Service issued a red high-level warning for the Andaman and Nicobar Islands, and also put out lower alerts for the coasts of Andhra Pradesh and Tamil Nadu states in the southeast of the country.  Sri Lanka issues tsunami warning across the island.  Thailand's disaster centre on Wednesday put provinces along the Andaman coastline on watch for a possible tsunami.  "We are still monitoring the situation but we've told the Andaman provinces to be on alert," the director of the National Disaster Centre, Somsak Kaosuwan, told Thai TV.  Smith Dhamasoroja, of the National Disaster Warning Foundation, predicted that the earthquake was of such a magnitude that it would create a tsunami that will "definitely" reach Thailand.  "Earthquakes of this size have the potential to generate a widespread destructive tsunami that can affect coastlines across the entire Indian Ocean basin," the US Pacific Tsunami Warning Centre said.  The tsunami warning centre said it had not yet ascertained whether a tidal wave had been generated but that one was likely given the strength of the temblor, and advised local authorities to take "appropriate action".  On December 26, 2004 a 9.2-magnitude earthquake off Sumatra generated a catastrophic tsunami that wrought devastation across southern Asia, killing an estimated 220,000 people.  Last year, a 9.0-magnitude earthquake caused a tsunami and nuclear disaster in Japan, killing about 19,000 people. - 9 News.
