Aftershocks demolish China homes

Two aftershocks have destroyed about 420,000 houses in the Chinese region hit by an earthquake two weeks ago, the official Xinhua agency says.

One of the aftershocks, in Qingchuan county, measured magnitude 5.7, according to the US Geological Survey.

The official death toll from the earthquake that hit Sichuan province on 12 May is 67,183. Another 20,790 people are listed as missing.

There were no reported causalities from the latest aftershocks, Xinhua said.

On Sunday 300,000 more homes were wrecked in Qingchuan by a strong tremor, which killed eight people and injured hundreds.

More than five million people remain homeless since the 12 May quake.

China Govt admits quake blame

Victims of China's earthquake have received the first public acknowledgement of Government culpability.

Lin Qiang, the deputy head of Sichuan education bureau, a senior official, spoke of his feelings of guilt for the deaths of thousands of children in poorly built schools and called on fellow officials to accept responsibility for schools which had collapsed because of shoddy workmanship.

Earthquake Near Chengdu, China

In late May 2008, a large lake continued to occupy a stretch of landslide-dammed river upstream of the small city of Beichuan, Shichuan Province. Landslides caused by the May 12 earthquake dammed a section of river with rocks and mud, and behind the barrier, the waters continued to rise.

This pair of images from Taiwan’s Formosat-2 satellite shows the lake on May 22 (top) and May 26 (bottom). The differences in color (especially the color of the lake) are probably due to the viewing conditions (viewing angle and time of day) during the satellite overpass, and not to actual changes in water clarity. Compared to a previous series of images that documented the filling of the lake, these images show much less change over the four-day period. The lack of obvious change may be an indication that the diversion channels being dug by Chinese engineers and soldiers had begun to drain the dangerous lake.

Naschok
De aarde schokt ondertussen nog steeds in de regio. Zondag veroorzaakte een schok met een kracht van 6,0 op de Richterschaal grote paniek in een deel van de provincie Sichuan. Voorts meldden media dat veel reddingswerkers het slachtoffer zijn geworden van aardverschuivingen. Die hebben ook tal van rivieren geblokkeerd, waardoor in het rampgebied nieuwe meren zijn ontstaan. Zeker drie van die meren zijn al overstroomd.

Chinees aardbevingsmeer 'extreem gevaarlijk'

DUJIANGYAN - Het enorme door een aardbeving gevormde meer in het Chinese aardbevingsgebied is extreem gevaarlijk. Ondanks dat militairen al ruim een week proberen het Tangjiashan-meer onder controle te brengen, zijn er nog steeds meerdere bedreigingen.

Een van de gevaren zijn naschokken, aldus een hoofdingenieur. Maar ook stijgt het waterniveau in het meer nog steeds. Het bevat meer dan 80.000 olympische zwembaden aan water.

Inmiddels is het waterpeil de top van de dam tot op 2,3 meter genaderd en is het nog maar de vraag of een afwateringskanaal dat militairen hebben gegraven afdoende is.

Evacuatie

De autoriteiten vrezen bij een doorbraak voor de een miljoen mensen die stroomafwaarts wonen. Zij hebben circa 200.000 mensen geėvacueerd naar hoger gelegen gebieden in de omgeving.

Chinees 'aardbevingsmeer' bereikt kritiek peil


PEKING - Het water in een meer in het zuidwesten van China dat door de aardbeving van 12 mei is ontstaan, heeft een kritiek niveau bereikt. Het is nu de bedoeling dat het water door een afwateringskanaal gaat stromen. Dat meldden Chinese staatsmedia zaterdag.

Militairen groeven het kanaal de afgelopen dagen om het waterpeil van het meer te controleren. Met ruim 220 miljoen kubieke meter water werd het zogenoemde Tangjiashan-meer het grootste meer dat door de aardbeving ontstond.

Het meer vormt een bedreiging voor tienduizenden mensen stroomafwaarts. De autoriteiten hebben ongeveer 200.000 mensen laten evacueren naar hoger gelegen gebieden in de omgeving.

Water in lake rising too fast!
BEIJING, China (CNN) -- Fears were mounting Monday for the safety of more than a million people downstream from a "quake lake" in China as waters threatening to burst a dam of landslide rubble were rising faster than engineers could drain them.

Authorities are concerned the Jianjiang River will top the dam unless efforts to dig and blast out emergency draining channels can drastically decrease the water level.

But engineers also risk letting out too much water at one time, which could also trigger a collapse of the dam created by a 7.9 magnitude quake that devasted China's Sichuan province.

"Increasing the outflow of water is critical for the dam's safety," said Zhang Ting, head of the Sichuan provincial hydro-meteorological bureau, the Xinhua news agency reported.

"If the water flows too slowly, the inflow will increase the pressure on the dam. But again, too voluminous an outflow can erode the diversion channel and cause the dam to collapse."

Water is flowing into the lake more than four times faster than it's flowing out, Zhang said

A 475-meter-long (1,560 foot-long) spillway for the water was completed more than a week ago, but engineers enlarged it over the weekend to increase the flow.

Chinese security forces have since dug a second channel and are working on a third, said Liu Yongjian, an army officer in charge of the work, the Xinhua news agency reported.

The so-called Tangjiashan quake lake formed after last month's devastating quake. Tons of rock and soil slid off a hillside, blocking the river.

Aftershocks continue to pepper the devastated region.

A pair of magnitude 5.0 quakes have rattled eastern Sichuan province over the last 24 hours.

Officials are concerned the building water pressure combined with the aftershocks could destablize the dam and send billions of gallons of water cascading down the river valley. Heavy rainfall could also strain the dam.


It could threaten up to 1.3 million people downstream. More than 250,000 people already have been been evacuated, Xinhua reported.

More than 69,000 people died in the May 12 quake, but more than 17,000 remain missing, according to the official government toll.

China Earthquake Was Rare Type

LiveScience.com Mon Jun 30, 12:46 PM ET

The major earthquake that devastated China last month was something of a seismological oddity, seismologists report in a new analysis. The faults that caused the temblor rarely rumble.

More than 69,000 people are confirmed to have died from the magnitude 7.9 quake that struck China's Sichuan province around noon on May 12, leveling school buildings and other poorly-constructed structures.

The earthquake was also a complete surprise to scientists. MIT seismologists who had been operating an array of 25 seismograph stations in the region for more than a year had found no hints that a large temblor might hit.

"Nobody was thinking there would be a major seismological event," in that area, said MIT's Leigh Royden. "This earthquake was quite unusual."

The region is extremely unusual geographically, Royden said, because of the very steep slopes at the boundary between the Sichuan Basin to the east and the Tibetan Plateau to the west. The elevation rises by more than two miles (about 3.5 kilometers) in a span of just 30 miles (50 kilometers).

The area is at the boundary between the Indian and Asian tectonic plates, which are engaged in an ongoing collision that has created the Himalayas and the Tibetan plateau.

In central and eastern Tibet, unlike most other areas where two continental plates are colliding, the movement of the crust is hidden. Instead of folding and faulting, the surface of the eastern Tibetan plateau is undeformed and being lifted upward by the thickening of a weak crustal layer more than 9 miles (15 km) below the surface.

The crust in this layer is flowing rapidly eastward away from central Tibet. But in the area where the earthquake occurred, it is obstructed by a major obstacle, the Sichuan Basin.

"The crust and mantle beneath the basin appears to form a hard, cold knot," Royden said, which forces the flow to "wrap around the knot." The huge elevation differences between the surface of the plateau and the Sichuan Basin provided the underlying stress that led to the quake, she added.

Similar events in the area occur only once in every 2,000 to 10,000 years on average, the researchers say, though they caution that because earthquakes can sometimes occur in clusters, residents and officials should still be wary of another possible large-scale earthquake.

The new analysis is detailed in the July issue of GSA Today, a publication of the Geological Society of America. The research was funded by the National Science Foundation.
