Hurricane Sandy (18L) – October 30th, 2012

As of 11 a.m. EDT (01500 UTC) October 30, Post-tropical Cyclone Sandy (18L) is located near 40.5°N 77.0°W, about 120 miles (190 km) ESE of Pittsburgh, Pennsylvania and about 145 miles (233 km) west of Philadelphia, Pennsylvania. Maximum sustained winds are 45 mph (72 km/h), with stronger gusts. Minimum central pressure is 983 mbar (hPa; 29.00 inHg), and the system is moving west at 10 mph (16 km/h).

Hurricane Sandy was the largest Atlantic hurricane in diameter on record, with its winds stretching about 1,100 miles from end to end. About 8 million customers have no electricity spread over 18 states from Maine to Virginia as of midday October 30. About half were in New York and New Jersey. More than 13,000 flights were canceled across the U.S. on October 29, and more than 3,500 were called off October 30. Sandy crippled 25% of wireless cell towers and a quarter of cable services in 10 states. Storm damage was projected at $30 billion to $50 billion, meaning it could prove to be one of the costliest natural disasters in U.S. history. As of October 30, 39 deaths have been reported in the U.S.

Earthquake Centered in Virginia Rocks US East Coast

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.

USA - October 12th, 2010

The cities of Baltimore, Maryland and Washington, DC can be observed near the east coast of the United States of America, in the upper right quadrant. Baltimore is located along the Chesapeake Bay, while Washington is further inland to the south.

A series of bays can be seen along the coast. North of the Chesapeake Bay is Delaware Bay, lighter in color. To the south of the Chesapeake are the Albemarle Sound and the Pamlico Sound (below the former), in the state of North Carolina. Greenish sediments and algal growth can be seen in both.

Southern USA - June 2nd, 2009

The Southern United States constitutes a large distinctive region in the southeastern and south-central United States. As defined by the US Census Bureau, this region includes sixteen states and the District of Columbia.

The Census Bureau also defined three smaller units, or divisions: the South Atlantic States, the East South Central States and the West South Central States.

The South Atlantic States division comprises Florida, Georgia, North Carolina, South Carolina, Virginia, West Virginia, Maryland, Washington, D.C., and Delaware.

The East South Central States unit is composed of Alabama, Kentucky, Mississippi and Tennessee.

Finally, the West South Central States division includes Arkansas, Louisiana, Oklahoma, and Texas.

Biologically, the South is a vast, diverse region, having numerous climatic zones, including temperate, sub-tropical, tropical, and arid.

However, the South is generally regarded as being hot and humid, with long summers and short mild winters, being significantly warmer than the rest of the country. Many crops grow easily in its soils and can be grown without frost for at least six months of the year.

Several geographical features of note in this image are the the bayous and swampland of the Gulf Coast (bottom), especially in Louisiana, the Appalachian Mountains (running diagonally across from the center to the upper right), and the Mississippi River (flowing vertically parallel to the left edge).
