Fire in Great Dismal Swamp in Virginia, USA – August 20th, 2011

August 20th, 2011 Category: Fires, Image of the day

USA - August 9th, 2011

A lightning strike in the Great Dismal Swamp National Wildlife Refuge on August 4, 2011, ignited the steadily growing Lateral West fire in southern Virginia. As of August 9th, the day this image was acquired, the fire had burned 2,000 acres. Fire fighters estimate that the fire will not be contained until August 31st.

Although a damp swamp may not seem like a prime location for a wildfire, the blaze is actually burning through dry grass and brush, dead vegetation left by a previous fire in 2008, as well as pine forest and soil.

In this image, the fire is producing dense smoke that is blowing towards the northeast. The majority of this smoke is because caused by soil dried by extreme heat and unusually dry weather, making it highly flammable and smoke-producing.

Albermarle Sound, USA - June 10th, 2009

Albemarle Sound is a large estuary on the coast of North Carolina in the United States located at the confluence of a group of rivers, including the Chowan and Roanoke.

It is separated from the Atlantic Ocean by the Outer Banks, a long barrier peninsula. Much of the water in the Albemarle Sound is brackish or fresh, as opposed to the saltwater of the ocean, as a result of river water pouring into the sound.

Here, the water of the sound appears dark blue and mostly clear of sediments. The waters of the Chesapeake Bay (partially visible, above) and the Pamlico Sound (partially visible, below), on the other hand, have a green tinge.

Inland, between Albemarle Sound and Chesapeake Bay, is the Great Dismal Swamp, a marshy region on the Coastal Plain of southeastern Virginia and northeastern North Carolina.

The dark blue circular area in its center is Lake Drummond, with a surface area of approximately 3,142 acres (13 km2) and a maximum depth of six feet.

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.
