A magnitude-6.5 undersea earthquake strike the western shore of Indonesia’s Sumatra Island on Friday, causing horror with no injuries or damages, an official said.

The quake struck late at nighttime 74 miles (119 kilometers) southeast of Pagai Selatan, an island off the western coast of Sumatra, Indonesian Meteorology & Geophysics.

The quake struck 6 miles under the Indian Ocean bed. There was no tsunami possible, he said. When quake strikes people fled their homes & rushed to higher ground. Indonesia rests on a sequence of fault lines that create the extensive archipelago nation one of the most earthquake-prone.

In Taiwan earthquake strike injuring 11 peoples, stopping transport & creates minor damage & fires. The quake also set off 5 fires, with one at a textile factory. Helicopters were used to drop extinguishers to help easiness the blaze.

Thursday morning a 6.4 Earthquake strike in Taiwan

1 response, Mar 04, 2010

An earthquake of magnitude 6.4 & depth 23.1km has struck a highly peopled area in the island of Taiwan region having the population as 22.4 million in China. GDACS approximations the likelihood for require of worldwide humanitarian intervention to be average.

The earthquake occurred at morning 8 local time. At the moment a day, more people are at work & therefore more in danger to collapsing office buildings. For the period of traffic hours, people can be affected by collapsing bridges & other road infrastructure.

The earthquake hit 44km from the city of Ping-tung. The nearby more peopled places are Ch’-nu (20km), P’ai-wan-she (19km), T’ao-lin (12km), Tun-na-tsun (12km). It is a rocky region with a maximum altitude of 3702 m.

The earthquake recorded today in Taiwan comes a few days following the shocking earthquake that hit Chile on 27 February this year minimum of 700 dead &  Haiti in January having the toll that go over 300 thousand victims.

Facts about Megathrust Earthquakes

No response, Mar 04, 2010

A megathrust earthquake is the border between a subducting and an intervening plate. A megathrust earthquake is produced by an unexpected slip along this fault. The world’s largest earthquakes are all refered as megathrust earthquakes.

While megathrust earthquakes have not been experiential in the short (~150 year) written history of the west coast of Canada, there is forceful evidence that they have happened in prehistorical periods. Some of this evidence includes:

• Covered tidal marsh or coastal forest soils point to an abrupt land subsidence of about 1 metre happening at the same time from Vancouver Island to Northern California.

• Alters in tree ring growth from coastal old-growth also suggest a sudden, extensive subsidence and drowning of roots.

• Sand layers on top of the covered coastal marshes, driven in from the offshore bars by the wave of the large tsunami that quick into the subsided coastal region.

• Silt landslide layers on the deep sea floor far off the coast from underwater mudslides, likely caused by strong seismic shaking.

• Tsunami evidence from:
local sources - marine organisms cleaned into and preserved in the bottom muds of coastal lakes that are separated from the ocean by land elevations of some 5 m high level.

distant sources - huge tsunami in Japan with no local Japanese earthquake. Representation this tsunami has exposed that the most recent earthquake for Cascadia was M ~9.0 and happened on January 26, 1700, at around 9 p.m.

NASA scientist says Chilean Quake may have shortened Earth Days

No response, Mar 03, 2010

JPL research scientist Richard Gross computed how Earth’s rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second).

Perhaps more impressive is how much the quake shifted Earth’s axis. Gross calculates the quake should have moved Earth’s figure axis (the axis about which Earth’s mass is balanced) by 2.7 milliarcseconds (about 8 centimeters, or 3 inches). Earth’s figure axis is not the same as its north-south axis; they are offset by about 10 meters (about 33 feet).

By comparison, Gross said the same model estimated the 2004 magnitude 9.1 Sumatran earthquake should have shortened the length of day by 6.8 microseconds and shifted Earth’s axis by 2.32 milliarcseconds (about 7 centimeters, or 2.76 inches).

Gross said that even though the Chilean earthquake is much smaller than the Sumatran quake, it is predicted to have changed the position of the figure axis by a bit more for two reasons. First, unlike the 2004 Sumatran earthquake, which was located near the equator, the 2010 Chilean earthquake was located in Earth’s mid-latitudes, which makes it more effective in shifting Earth’s figure axis. Second, the fault responsible for the 2010 Chiliean earthquake dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake. This makes the Chile fault more effective in moving Earth’s mass vertically and hence more effective in shifting Earth’s figure axis. Gross said the Chile predictions will likely change as data on the quake are further refined.

Chile’s President agrees raiding Will Be under Control

No response, Mar 02, 2010

Chile’s President Michelle Bachelet says above 2 million buildings, including 500,000 homes, were spoiled in Saturday’s shocking earthquake. President Bachelet said on Tuesday it is not possible to know at this time which buildings can be remake & which should be pointed.

Ms. Bachelet too said she didn’t have a correct death toll from the earthquake, but is receiving updates each 2 to 3 hours.  The death toll now stands at around 720. Secretary Clinton said the U.S. is ready to help Chile well it can.  She brought with her disaster communications equipment & technical hold up.

Earlier Tuesday, President Bachelet said that raiding & lawlessness will not be tolerated.  She has instructed troops to act with what she called the “severity” necessary to avoid crime. The president has already sent minimum of 10,000 soldiers to cities affected by the earthquake to restore order.

Chile quake far bigger except less deadly than Haiti

2 responses, Mar 01, 2010

PARIS — The Chile earthquake unconfined around 1,000 times more power than the one that overcome Haiti in January, except than left 200 times less fatalities. Aided personnel in Chile are still finds for the survivors of the earthquake which struck on Saturday. More than 700 peoples are now believed to have died, & 2 million have missed their homes.

Chile is a more successful country, by economic output per head of the population more than 10 times better than Haiti. That has meant that buildings in common are better built, but Chile was also better organized. Public in Chile knew the secured places to go to when the earthquake hit.

Tomorrow a field hospital is arriving to conception from Argentina! One more benefit for the Chilean quake was that its epicenter was 21 miles underground, off-shore & 70 miles from the adjacent big city, Concepcion. The energy from earthquakes falls the more away you are from the centre. The Haitian quake on the added hand over was only 8 miles underground & right on the edge of Port-au-Prince.

Double earthquakes shakes Mindanao

No response, Feb 26, 2010

DAVAO CITY, Philippines-A 5.1 magnitude earthquake Struck off in General Santos City at 12:19 a.m. Saturday, hardly 8 hours after one more moderate earthquake hit Southern Mindanao, the United States Geological Survey statement said.

There were no instant reports of damage or injuries from the tectonic quake that had a depth of 53.7 kilometers. The hottest jolt was traced 74 kilometers east-southeast of General Santos City & was felt as much as Cotabato City & Davao city.

The Philippines sits on the supposed Pacific Ring of Fire & has daily bouts with earthquakes, some of which are also weak to be felt. Earthquakes in Mindanao & in other parts of the country are usually caused by the faction of the tectonic plates.

One of the deadliest quakes took place in Central & Western Mindanao in August 1976. The magnitude 7.6 jerk started a tsunami that killed more than 3,000 people & flattened millions of pesos in properties.

An earthquake 5.1 hit southwest China

No response, Feb 25, 2010

A moderate 5.1 earthquake has hit the southwest region of China & missing 23 people injured as more residential homes were collapsed.

An earthquake calculated at 5.1-magnitude struck the southwest region of Yunnan in China On Thursday, according to the United States Geological Survey. The earthquake’s strength was measured at 24.4 miles & it was positioned 60 miles of northwest of Kunming & 1,300 miles southwest of Beijing.

Local authorities publicized there were 23 people wounded as dozens of houses collapsed but no damages to heritage sites have been reported. The Yunnan Provincial Red Cross humanity & provincial authorities have sent aid efforts & aid supplies, containing quilts, tents, clothes & extra vital items to the area, reports said.

Earthquake engineers release statement on damage in Haiti

1 response, Feb 24, 2010

WASHINGTON: A team of earthquake engineers has out information on the damage done in Haiti after the 7.2 quake on January 12. “The need of the people combined with the density of population & more building codes resulted in the extensive damage,” told Eberhard.

A major report is that much of the loss of human life might have been prevented by using earthquake-resistant models & construction, plus improved quality control in concrete & masonry work. The creators of the report suggest that simple & cost-effective earthquake production be highlighted in Haiti’s rebuilding effort.

They also gathered more seismic data similar to Earthquake monitoring stations were not having in Haiti. Identifying the location will help what caused the earthquake and forecast the likelihood of future quakes in the area.

The team submits a ground assessment of places that were most evil hit, including the port in Port-au-Prince, the cathedral, the National Palace, the Hotel Montana & the Union School, attended by children of more nationalities. A review of 107 buildings in a heavily damaged portion of downtown Port-au-Prince found that 28 percent had distorted & a 3rd would require repairs.
