U.S. Geological Survey

The United States Geological Survey (USGS) is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. http://www.usgs.gov/

Northern Honshu devastated

"Rescuers struggled to reach survivors on Saturday morning as Japan reeled after an earthquake and a tsunami struck in deadly tandem. The 8.9-magnitude earthquake set off a devastating tsunami that sent walls of water washing over coastal cities in the north. Concerns mounted over possible radiation leaks from two nuclear plants near the earthquake zone."

Karangetang

Just hours after the earthquake stuck Japan, triggering a powerful tsunami, a volcano has erupted in Indonesia. This is one of Indonesia’s most active volcanos, Mount Karangetang

NOAA-DART forecasting

DART (Deep-ocean Assessment and Reporting of Tsunamis) is a service for real-time monitoring the ocean waves. The network has sites positioned at strategic locations throughout the ocean and play a critical role in tsunami forecasting. http://nctr.pmel.noaa.gov/Dart/

"Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. The speed of tsunami waves depends on ocean depth rather than the distance from the source of the wave. Tsunami waves may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters. While tsunamis are often referred to as tidal waves, this name is discouraged by oceanographers because tides have little to do with these giant waves."http://oceanservice.noaa.gov/facts/tsunami.html

Distant galaxy helped relight the universe

"The discovery of a small but distant galaxy 12.8 billion light years from Earth is providing important clues about the earliest years of the universe's life. By measuring the age of the galaxy's stars, astronomers in Europe and the US say the galaxy began to shine when the universe was just 150–300 million years old. The work suggests that such galaxies were responsible for dispersing the atomic fog that once cloaked the cosmos, during a period in the history of the universe that astronomers know very little about." by Ken Croswell
