Quake off eastern Russia may be biggest-ever deep temblor

 

24 May 2013 | 16:06 BST| Posted by Alexandra Witze | Category: Earth, environment & ecology, Natural disasters

Posted Image An extraordinarily deep earthquake shook Russia’s Far East this morning. The magnitude-8.3 quake took place nearly 610 kilometres below Earth’s surface, according to preliminary estimates from the US Geological Survey.

Normally rocks at this depth are too hot to rupture quickly in a quake; instead, they deform slowly, like hot wax flowing rather than cold wax shattering. But beneath the Sea of Okhotsk, north of Japan and west of Russia’s Kamchatka Peninsula, the sea floor — a slab of old Pacific crust — is diving beneath Eurasia. The crust is descending fast enough — about 8 centimetres per year — to remain cool enough to rupture even at great depths. The diving plate is thus seismically active down to 650 kilometres or greater.

They seem to be changing the location as they refine reports. At first it was reported by EMSC as being only 10 km away from Tashkent and is currently cited as being 32 km away. At 10 km depth, though, it might be nasty, given the geology. So far, local press aren't reporting any damage.

Mexico: 5.8 Magnitude Earthquake Strikes
 
Earthquake tremors were felt in the capital Mexico City but there have not been any reports of casualties or extensive damage.
 
A 5.8 magnitude earthquake has struck Mexico with tremors felt in the captial Mexico City, says the US Geological Survey. There were no immediate reports of damage or casualties but power was lost in some areas of Mexico City. Mexico City mayor Miguel Angel Mancera said on Twitter although the quake was felt strongly in the capital, "in the preliminary report, Mexico City was not damaged".
 
A witness said buildings, which were evacuated as a precautionary measure, also shuddered in the capital. The epicentre of the quake was 14 miles (22km) west of the town of Jolalpan and had a depth of 33 miles (54km). The USGS downgraded its initial measurement of the quake from 6.0 to 5.8.
