AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS ORIGIN TIME - 0839Z 11 APR 2012 COORDINATES - 2.3 NORTH 93.1 EAST LOCATION - OFF W COAST OF NORTHERN SUMATRA MAGNITUDE - 8.7

EVALUATION

 EARTHQUAKES OF THIS SIZE HAVE THE POTENTIAL TO GENERATE A
 WIDESPREAD DESTRUCTIVE TSUNAMI THAT CAN AFFECT COASTLINES ACROSS
 THE ENTIRE INDIAN OCEAN BASIN.

 HOWEVER - IT IS NOT KNOWN THAT A TSUNAMI WAS GENERATED.  THIS
 WATCH IS BASED ONLY ON THE EARTHQUAKE EVALUATION. AUTHORITIES IN
 THE REGION SHOULD TAKE APPROPRIATE ACTION IN RESPONSE TO THE
 POSSIBILITY OF A WIDESPREAD DESTRUCTIVE TSUNAMI. WE ARE STILL
 WAITING FOR CONFIRMATION OF TSUNAMI FROM NEAREST SEA-LEVEL
 STATIONS.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

Indian Ocean Tsunami Travel Time Map


A magnitude 9.1 Mw earthquake occurred off the west coast of Sumatra, Indonesia, on December 26, 2004. It was the fourth largest earthquake in the world since 1900 and the largest since the 1964 Prince William Sound, Alaska, earthquake. The earthquake generated a tsunami that caused more casualties than any other in recorded history. The tsunami was recorded nearly world-wide on tide gauges in the Indian, Pacific and Atlantic Oceans. In total, more than 227,8980 people were killed or missing and 1,126,900 were displaced by the earthquake and subsequent tsunami in 14 countries in South Asia and East Africa. Source:  NGDC

Tsunami Evaluation

A DESTRUCTIVE WIDESPREAD TSUNAMI THREAT DOES NOT EXIST BASED ON HISTORICAL EARTHQUAKE AND TSUNAMI DATA. HOWEVER, THERE IS A VERY SMALL POSSIBILITY OF A LOCAL TSUNAMI THAT COULD AFFECT COASTS LOCATED USUALLY NO MORE THAN A HUNDRED KILOMETERS FROM THE EARTHQUAKE EPICENTER. AUTHORITIES IN THE REGION NEAR THE EPICENTER SHOULD BE MADE AWARE OF THIS POSSIBILITY:  PACIFIC TSUNAMI WARNING CENTER

Damage Report

There was no report of damage or casualties as of posting; however, news agencies quoted a spokesman for Indonesia’s earthquake agency as saying: “In Cilacap people were panicking—most of them are evacuating to higher ground.”

The agency reported the quake as a 7.1 magnitude striking at a depth of 10km with the epicenter located at about 300km from Cilacap, south coast of Java island, Indonesia.

Merapi’s latest eruption the deadliest so far

Posted by feww on November 5, 2010

The latest eruption of Mount Merapi volcano claims about 70 lives; hundreds more injured

Mt Merapi volcano’s latest salvo of eruptions began on October 26, 2010.  On Thursday, it blasted hot ash and poisonous volcanic fumes into the air, killing about 70 more people, reports say.

The blast has burned villages up to 15km (9 miles) from the summit crater.

Indonesian President Bambang  declared the eruption a national disaster on Friday. Up to 100,000 people have now abandoned dozens of villages on the slopes of the volcano. The death toll from the continual 10-day eruption has now climbed to at least 115.

Mt Merapi’s Eruption: Satellite Image

(2 MB, JPEG) — Image acquired November 1, 2010 – Posted on November 5, 2010.

ASTER on NASA’s Terra satellite captured the thermal signature of hot ash and rock and a glowing lava dome on October 30.  The thermal data is overlaid on a three-dimensional map of the volcano to show the approximate location of the flow. The three-dimensional data is from a global topographic model created using ASTER stereo observations.

Merapi shows no signs of slowing. After several days of eruptive episodes, the volcano began an eruption on November 3 that was five times more intense than on October 26 and lasted more than 24 hours. It is the most violent eruption at the volcano since the 1870s, said local geologists. (Source: NASA-EO).

Mount Merapi Erupts Repeatedly

Posted by feww on October 29, 2010

Mount Merapi erupted at least six times Friday, spewing ash and lava

Indonesia’s Mount Merapi volcano erupted repeatedly on Friday, spewing ash and lava, reports say.

The plume reportedly rose to a height of  about 1,500 meters (~ 5,000 feet).

Mount Merapi, located north of the Yogyakarta, on the densely populated island of Java, is one of Indonesia’s most active volcanoes.

Merapi, one of Indonesia’s most active volcanoes, lies in one of the world’s most densely populated areas and dominates the landscape immediately north of the major city of Yogyakarta. Merapi is the youngest and southernmost of a volcanic chain extending NNW to Ungaran volcano. Growth of Old Merapi volcano beginning during the Pleistocene ended with major edifice collapse perhaps about 2000 years ago, leaving a large arcuate scarp cutting the eroded older Batulawang volcano. Subsequently growth of the steep-sided Young Merapi edifice, its upper part unvegetated due to frequent eruptive activity, began SW of the earlier collapse scarp. Pyroclastic flows and lahars accompanying growth and collapse of the steep-sided active summit lava dome have devastated cultivated lands on the volcano’s western-to-southern flanks and caused many fatalities during historical time. The volcano is the object of extensive monitoring efforts by the Merapi Volcano Observatory. Photo by Yustinus Sulistiyo, 1994 (Volcanological Survey of Indonesia); caption: GVP

Tsunami Claims 200 After 7.7Mw Quake Strikes Indonesia

Posted by feww on October 26, 2010

At Least 200 Dead or Missing After Tsunami Created by Powerful Quake Destroys Villages Off Western Indonesia

At least 10 villages were obliterated by a 3-m high tsunami created after a 7.7Mw quake struck off the Mentawai islands, Sumatra, western Indonesia.

A huge white wave which was created by the quake washed away  just about everything in sight, eyewitnesses said.

At least 25 people are confirmed dead with about 170 others [local officials say at least 380 people] reported  as missing.

Powerful Earthquake Strikes Southern Sumatra, Indonesia

Magnitude 7.9 earthquake strikes southern Sumatra, Indonesia

Magnitude 7.9 earthquake struck southern Sumatra, Indonesia, 50 km (30 miles) WNW of Padang, at a depth  of about 85 km on Wednesday, September 30, 2009 at 10:16 UTC, USGS/EHP reported.

Only hours ago, having briefly analyzed details of the Samoan earthquake, FEWW had foretasted that up to 3 more powerful quakes could strike the Pacific Ring of Fire in 2009.

Four weeks ago a deadly earthquake measuring  7.3 to 7.6 Mw struck off the coast of Java, Indonesia, killing more than 80 people and injuring at least another 1,250.

Tsunami Warning

Pacific Tsunami Warning Center (NOAA) has issued a tsunami warning based on the size and location of the earthquake for countries bordering Indian Ocean: Indonesia, India, Thailand and Malaysia.

Damage Report

“People are panicking. They are running out of the buildings… There are many collapsed buildings,” an eye-witness in Padang told a local TV station.

“Hundreds of houses have been damaged along the road. There are some fires, bridges are cut and there is extreme panic here maybe because water pipes are broken and there is flooding in the streets,” another witness told Reuters.

“Hundreds of houses have been damaged along the road,” another eye-witness in Padang said.

“There are some fires, bridges are cut and there is extreme panic here maybe because water pipes are broken and there is flooding in the streets.”

Padang has a population of just under 1,000,000 people. There were no reports of casualties as of posting; however, given that so many buildings have collapsed, it’s more than likely that many people would have been killed or injured.

According to a local report, power and phone lines are down in Pandang and several other parts of Indonesia.

The mainshock was followed by a strong aftershock measuring 6.0  GFZ Potsdam/ Earthquake Bulletin reported. More strong aftershocks are highly probable.
