Scores dead, injured following Indonesian earthquake

A powerful magnitude-7.0 earthquake struck a few kilometers off the coast of West Java, Indonesia, at 2:55 p.m. local time on Wednesday, according to the U.S. Geological Survey. NOAA's Pacific Tsunami Warning Center issued a tsunami warning for the immediate region, but canceled it within an hour when no tsunami was detected.

Moonquake mystery deepens

Between 1969 and 1972, five Apollo missions installed seismic stations at their landing sites on the nearside of the moon. Because the moon was thought to be seismically dead, the instruments were left almost as an afterthought to detect meteor strikes. But from the time the stations were switched on until they were decommissioned in 1977, they recorded hundreds of internally generated moonquakes, some as strong as magnitude 5.5 on the Richter scale.

Benchmarks: August 17, 1959: Hebgen Lake earthquake and landslide

By Callan Bentley

You’re camping in Montana, doing some fly fishing on the Madison River. You’ve had a full day of beautiful Big Sky country weather, and had fresh trout for dinner. In your campsite at the Rock Creek Campground, you go to bed satisfied and happy. It’s a nice enough evening that you sleep out in the open, to better appreciate the stars. The waters of the Madison gurgle by, gently lulling you to sleep while Orion shines above.

Asia's hazardous month

Earthquake shakes southern New Zealand

A magnitude-7.6 earthquake rattled the South Island of New Zealand at 8:22 p.m. local time Wednesday. No serious injuries or damages have been reported.

The quake's epicenter was 150 kilometers west of Invercargill, off the coast of New Zealand's South Island at a depth of 12 kilometers, according to the U.S. Geological Survey’s Earthquake Hazards Program. Subsequent to the major tremor, the region has experienced several aftershocks ranging in magnitude from 5 to 5.8.

When and why L'Aquila came tumbling down

Early on the morning of April 6, 2009, a magnitude-6.3 earthquake rocked the Apennine region of central Italy, killing more than 290 people and leaving at least 30,000 homeless. Some 15,000 buildings were damaged or destroyed in L’Aquila, the largest city in the region. Although strong, the earthquake was not powerful enough to easily account for the high loss of life in a developed country. The devastation has prompted some researchers to investigate Italy’s seismic safety codes for new construction — but the problem may have more to do with retrofitting older buildings.

Earthquake prediction: Gone and back again

The 1990s and early 2000s were hard times for earthquake prediction research. “For 10 years, there was limited funding in the U.S.,” says Dimitar Ouzounov, a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md., and professor at Chapman University in Orange, Calif. That changed in 2004, Ouzounov says, after a magnitude-9-plus quake struck off the coast of Sumatra and set off a tsunami, killing more than 225,000 people in 11 countries.
