Fires in Maryland and Virginia

Fires in Maryland and Virginia
Several brush fires popped up in Maryland and Virginia on February 19, 2011. The fires are outlined in red in this image taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite in the early afternoon. Long plumes of smoke stretching away from the fires are evidence of the strong winds that fueled the fires. The winds gusted to 50 miles per hour (80 kilometers per hour).
The dry and windy weather conditions on February 19 proved a dangerous combination for wildfires. On top of that, winter rain and snow have been sparse in the region and the vegetation is dry.
The fires forced evacuations and smoke closed parts of Interstate 95. The interstate’s path is visible in the image by the cement-colored urban areas that surround the road north and south of Washington, D.C.

Magnitude 6.3 Earthquake near Christchurch, NZ

Magnitude 6.3 Earthquake near Christchurch, NZ
At 12:51 p.m. local time on February 22, 2011 (11:51 p.m. February 21 UTC), a 6.3-magnitude earthquake struck the South Island of New Zealand, the U.S. Geological Survey (USGS) reported. Several smaller aftershocks followed. The quake occurred near the city of Christchurch, a community of some 400,000 residents on the east coast. The initial death toll was 65, according to news reports, and authorities warned that the toll could rise sharply as search-and-rescue efforts continued.
This map shows the earthquakes that occurred near Christchurch since September 3, 2010. On that day a magnitude 7.1 quake struck to the west of Christchurch. Black circles represent earthquakes from September 3, 2010, until February 21, 2011. Red circles show the locations of the magnitude 6.3 quake and aftershocks on February 22 and the morning of February 23. Larger circles represent stronger earthquakes. Yellow shows urban areas, including Christchurch.
The USGS characterized the 6.3-magnitude quake on February 22 as an aftershock of the quake that struck to the west, in Darfield, New Zealand, on September 3, 2010. Darfield lies about 50 kilometers (30 miles) west-northwest of Christchurch. Although no specific tectonic structure linked the two events, numerous aftershocks of the September quake occurred along a roughly east-west line, as this image indicates. The USGS stated that the quakes were associated with regional tectonic plate boundary deformation. The Pacific Plate and the Australia Plate interact under the South Island of New Zealand.
The Darfield earthquake in September 2010 caused no casualties, even though it had a higher magnitude. Besides striking closer to a major population center, the 6.3-magnitude Christchurch earthquake had a depth of just 5 kilometers (3 miles). The New Zealand Herald reported that, whereas the Darfield quake happened in the early morning hours, the February 22 quake struck at the “worst possible time” of day—at the lunch hour when city streets were crowded with shoppers, diners, office workers, and school children. Moreover, some of the buildings that collapsed may have been weakened by the September 2010 quake.
Effects of the Christchurch earthquake were felt some 200 kilometers (125 miles) away, along the South Island’s west coast. A 30 million-tonne (33 million-ton) chunk of ice broke off from the Tasman Glacier, and slid into Tasman Lake. In fact, officials had expected ice would break off the glacier, although they expected the event to result from heavy rainfall caused by La Niña.

Activity at Kizimen Volcano

Activity at Kizimen Volcano
On February 22, 2011, the U.S. Air Force Weather Agency reported that Kizimen Volcano erupted an ash plume to an altitude of 9,000 feet (2,700 meters). The plume extended 60 nautical miles (110 kilometers) to the east, towards Kamchatskiy Zaliv (the Gulf of Kamchatka). The plume is light colored, suggesting a high concentration of water vapor. Brown ash covers the snowy landscape downwind of the summit, the result of frequent emissions since Kizimen began erupting in early December, 2010. This natural-color satellite image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard Aqua on February 22, 2011.
