Tsunami preparedness briefing on Capitol Hill stresses disaster education
A year after the tsunami that devastated the Japanese coastline, the United States still needs to ramp up its tsunami preparedness, experts say. Scientists at a March 21 Capitol Hill briefing in Washington, D.C., stressed the importance of detecting tsunamis before they reach coastlines and educating the public on tsunami dangers.

Japanese megaquake triggered tiny California tremors
As southern Californians absorbed the news of the devastating March 11 earthquake in Japan, seismic instruments under their feet sensed the shocks as well.

Cloudy with a chance of earthquakes
Some earthquakes occur underneath abnormally warm patches of atmosphere that form just hours or days before the Earth starts to rumble, according to preliminary reports from American and Russian scientists.

Atmospheric electrons may act differently before megaquakes
Just before the recent huge earthquake in Japan, electron counts in the atmosphere high above the epicenter took a surprising turn, a new study indicates. Measurements gleaned from GPS satellites recorded more electrons in the ionosphere over the soon-to rupture fault than expected. A similar uptick occurred before extra-large quakes in Chile in 2010 and Sumatra in 2004, the researcher found.
A tantalizing question for seismologists and atmospheric scientists is whether this high-altitude electron bump, if confirmed by other studies, is a true early-warning signal for devastating earthquakes.

Earthquake monitoring with smartphones and websites
Want to contribute to earthquake science? Your smartphone can be an earthquake measuring device. Researchers at the University of California, Berkeley have been developing a smartphone application that uses the phone to measure acceleration during an earthquake and report that data to researchers for processing. Shideh Dashti of the University of California Berkeley reported on initial tests of the system in Fall Meeting’s session S51E: Engaging Citizens In the Collection …

Warning: Shaking, rattling, and rolling about to occur
Scientists in Japan have developed an earthquake warning system–and though it doesn’t predict earthquakes, it does provide several seconds of warning time. The warning interval varies, depending on the distance to the quake’s epicenter.
That early warning system, Kinkyu Jishin Sokuhou in Japanese, was the topic of a presentation by Kyoto University’s Jim Mori during Thursday afternoon’s session NH43B: Transmitting Hazard Science to End Users: What Works, What Doesn’t, and What’s Needed? II.

Capitol Hill briefing: What we can learn from the Haitian earthquake of 2010
The 7.0 magnitude earthquake that struck Haiti on 12 January caused disproportionate havoc relative to its magnitude: At least 230,000 people died and scores of schools, government buildings and houses were destroyed. In comparison, the 8.8 magnitude earthquake that hit Chile a few weeks later, an event so large that might have shifted Earth’s axis, killed less than 500. To analyze the causes of the massive destruction in Haiti and …

U.S. House of Representatives Acts to Reduce Hazards
The U.S. House of Representatives approved last week a bill that renews two important federal programs aimed at mitigating and reducing destruction from natural disasters. This legislation, H.R. 3820, the Natural Hazards Risk Reduction Act of 2010, was approved on 2 March with a vote of 335-50. First, the bill renews the National Earthquake Hazards Reduction Program (NEHRP), which was created in 1977. Not only is NEHRP responsible for developing …

Session Videos on Climate, the L’Aquila Earthquake, and the Long Solar Minimum
Videos of several lectures of FM09 are now available online! In addition to most of named lectures on Monday and Tuesday, you can also catch glimpses some union and section lectures. For example: On Sunday, the “Intercontinental Sessions” included two taped talks, one by Matthew Nisbet of American University’s Center for Science, Society, and the Environment, and one by Gwendolyn Blue of the University of Calgary’s Communication and Culture department. …
