Levee break from the Sky

As the weather cleared in New Orleans officials were able to move in and begin rescue operations. However, a hole in the levee holding back the salty waters of Lake pontchartrain has been widening throughout the day. This hole is causing flood waters to steadily rise, flooding areas that had originally escaped inundation.

New Orleans's Ray Nagin said, "We're not even dealing with dead bodies...They're just pushing them on the side." This is a very gruesome situation. Although the bacteria that start the decay process when a human body dies is not dangerous to other humans, many other toxic substances pollute that waters flooding New Orleans.

Mount St Helens—the most active volcano in North America—erupted again on Tuesday, March 8, sending a cloud of ash and steam seven miles into the air. The venting began about an hour after a 2.0 magnitude earthquake shook the east side of the volcano, which has been mostly quiet since a few eruptions last September and October.

(A major eruption in 1980 killed 57 people, destroyed 200 homes, and reduced the height of the mountain's summit from 9,677 feet to 8,364 feet.)

Mount St Helen's is one of the most studied volcanoes in the world, and sensors show that lava moving into the crater left by the 1980 eruption has pushed the lava dome within the crater up by 500 feet. Scientists don't expect a major eruption, although they say that a bigger eruption could drop ash within a 10-mile radius of the crater at any time. Recent flights over the crater haven't measured high levels of gases. Instead, researchers think the volcano will continue to grow, as it did in 1986, with a series of small eruptions and a lava-dome building phase.

"The Indian Ocean tsunami that hit southern Asia on December 26 has uncovered a series of temples in southern India.

"Archaeologists have begun underwater excavations of what is believed to be an ancient city and parts of a temple uncovered by the tsunami off the coast of a centuries-old pilgrimage town.

"Three rocky structures with elaborate carvings of animals have emerged near the coastal town of Mahabalipuram, which was battered by the Dec. 26 tsunami.

"Mahabalipuram is already well known for its ancient, intricately carved shore temples that have been declared a World Heritage site and are visited each year by thousands of Hindu pilgrims and tourists. According to descriptions by early British travel writers, the area was also home to seven pagodas, six of which were submerged by the sea."
