Earthquake Centered in Virginia Rocks US East Coast

38.0N 77.9W

August 23rd, 2011 Category: Earthquakes, Fires

USA and Canada - August 15th, 2011

The East Coast of the USA was rocked by a 5.9 magnitude earthquake Tuesday, shaking buildings in many cities, delaying flights and trains and sending thousands of frightened workers into the streets, although there have been no reports of major damage or injuries

The earthquake was centered in about 4 miles southwest of Mineral, Virginia, near Richmond, Virginia, and about 80 miles south of Washington, D.C. Its effects were strongest in the Mid-Atlantic region, although it was felt from as far north as Ottawa, Canada, to North Carolina, in southern USA. This image shows part of the eastern seaboard, including most of Virginia.

The U.S. Geological Survey reported that at the epicenter, the quake had a very shallow depth of 0.6 mile. It hit at about 1:51 p.m. ET and lasted 45 seconds, according to the U.S. Geological Survey. The USGS has warned of the possibility of aftershocks.

Earthquakes of magnitude 5.5 to 6 can cause damage to buildings and other structures, especially if shallow. The U.S. East Coast does not normally feel quakes of this strength. However, the shallower a quake is, the more intense it is felt on the surface, and the potential for damage is greater.

Also visible in this image of some of the areas affected by the earthquake is a fire burning in the Great Dismal Swamp in Virginia (visible in full image). The blaze has been burning since the 4th of August.

 

New Earthquake Felt in Northeast Japan – July 30th, 2011

Fukushima - July 19th, 2011

A 6.4 magnitude earthquake has been felt in northeast Japan, shaking buildings in the capital Tokyo, reports say. The quake’s epicentre was off the east coast of Honshu. The main orthorectified image focuses on the northeastern coast of that island on the day of the recent quake.

It struck in the same area as the 11 March earthquake and tsunami but no abnormalities at Japanese nuclear plants were reported, Reuters reports. There were no immediate reports of damage or injuries and no tsunami warning was issued.

More than 20,000 people died or were reported missing as a result of the disaster in March, which also crippled nuclear reactors in the Fukushima area. The detail image, also orthorectified, gives a recent view of that area, with Tokyo partially visible at the bottom upon opening the full version.

Sendai 3D

Sendai  is the capital city of Miyagi Prefecture, Japan, and the largest city in the Tōhoku Region.

On 11 March 2011, coastal areas of the city suffered catastrophic damage from a magnitude 9.0 offshore earthquake and the tsunami that it caused.
Although not much damage occurred in the city center, major damage was reported in the coastal areas including Sendai Airport. The tsunami reportedly reached as far as Wakabayashi Ward Office, 8 kilometers (5.0 mi) from the coastline.

The images here were processed by Chelys’ new raw data processor. The main image shows Sendai and its coastal areas, one detail image offers a 3D view of the area, and the other shows the location of a nuclear power plant.

Islands of Japan Day After Massive Earthquake – March 18th, 2011

Damage from Tsunami

10-metre (33-ft) High Tsunami

This image shows the islands of Japan one day after the 2011 Tōhoku earthquake and tsunami afflicted the country. The 9.0 magnitude earthquake occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011.

The epicenter was 130 kilometers (81 mi) off the east coast of the Oshika Peninsula of Tōhoku near Sendai, with the hypocenter at a depth of 32 km (19.9 mi). Here, the land closest to the quake epicenter is partially obscured by clouds, although the city of Tokyo can be seen clearly to the south.

The earthquake triggered extremely destructive tsunami waves of up to 10 meters (33 ft) that struck Japan minutes after the quake, in some cases traveling up to 10 km (6 mi) inland, with smaller waves reaching many other countries after several hours. Tsunami warnings were issued and evacuations ordered along Japan’s Pacific coast and at least 20 other countries, including the entire Pacific coast of North America and South America.

Ship Tracks off the Coast of Chile

Argentina - October 12th, 2010

The two opaque white parallel lines of clouds cutting through the more through the translucent surrounding cloud cover are an atmospheric phenomenon known as ship tracks. Similar to airplane condensation trails, they form when water molecules gather around the exhaust released into the air by ships.

Parts of Chile and Argentina can be seen in the right half of the image. Although much of Chile is obscured by heavy cloud cover, some snow-capped ridges of the Andes Mountains can be observed, and the Argentine Patagonia terrain is cloud-free.

In related news about Chile, a 5.8-magnitude quake shook the central part of the country late on Wednesday, swaying buildings in the capital Santiago, but causing no damage, emergency officials said.

The quake’s epicenter was offshore in the Pacific Ocean 196 miles west-southwest of Santiago and at a depth of 4.2 miles (6.7), the U.S. Geological Survey said.

In February, Chile was struck by an 8.8-magnitude quake, one of the biggest in recorded history, killing more than 500 people and ravaging towns and industries in south-central Chile.
