After Sandy, Testing the Waters

November 19, 2012

During Hurricane Sandy the seas rose a record 14-feet in lower Manhattan. Water flooded city streets, subways, tunnels and even sewage treatment plants. It is unclear how much sewage may have been released as plants lost power or were forced to divert untreated wastewater into the Hudson River.
2010 Korea Bomb ‘Tests’ Probably False Alarms, Says Study

October 02, 2012

This spring, a Swedish scientist sparked international concern with a journal article saying that radioactive particles detected in 2010 showed North Korea had set off at least two small nuclear blasts--possibly in experiments designed to boost the yields of much larger bombs. Shortly after, the pot was stirred with separate claims that some intelligence agencies suspected the detonations were done in cooperation with Iran. Now, a new paper says the tests likely never took place—or that if they did, they were too tiny to have any military significance. The new report, by seismologists at Columbia University’s Lamont-Doherty Earth Observatory, will be published later this month in the journal Science & Global Security, where the earlier paper also appeared.
Magnitude 5.8 Quake Rattles East Coast

August 24, 2011

The magnitude 5.8 earthquake that shook central Virginia on Tuesday afternoon is one of the biggest earthquakes to hit the East Coast since 1897, and was comparable in strength to a quake on the New York-Canadian border in 1944, according to the U.S. Geological Survey. It was centered near Mineral, Va., about 38 miles northwest of Richmond, and in an area known for frequent though lesser quakes.
