Using data supplied by a mobile operator, researchers at Karolinska Institutet have shown that population movements after the 2010 Haiti earthquake followed regular patterns. This information can be used to predict beforehand the movements of people after a disaster, and thus improves chances for aid to be delivered to the right places at the right time. Every year, tens of millions of people are displaced by natural disasters, and to date knowledge of their movement patterns has been...

National Research Council Punts On Fracking-related Earthquakes
2012-06-18 13:44:12

DM Crumbliss The National Research Council folded to pressure from the fossil fuel industry and pro-fracking Congress members last week by releasing a “more study needed” report on fracking and earthquakes. The report was requested by members of Congress. The stakes are simply high enough that the council is unwilling to strongly state the obvious. The report says, “Keep fracking, these earthquakes are no big deal.” Earthquake activity has jumped significantly in...

Global seismic hazard maps exist to help societies and decision-makers anticipate and prepare for earthquakes. These maps are supposed to depict the maximum level of ground shaking likely to be produced by an earthquake in a given area. In the past decade, however, ground motions and death tolls in areas struck by earthquakes have far exceeded these maps' projections. Thus, scientists are calling into question the standard methods used to estimate seismic risk, and accepted assumptions and...

Another Earthquake Rocks Northern Italy Killing At Least Ten
2012-05-29 08:30:06

Northern Italy on Tuesday was shaken by a magnitude 5.8 earthquake, killing at least ten people, less than two weeks after a magnitude 6.0 temblor rocked the same region, destroying castles, churches and leaving seven dead, according to local Italian news agencies. The US Geological Society said the quake struck at 9:00 a.m. local time and was centered about 25 miles northwest of the central city of Bologna. The quake was felt throughout northern and central Italy, including Milan and...

Caltech Researchers Gain Greater Insight Into Earthquake Cycles

New dynamic computer model first to show full history of a fault segment For those who study earthquakes, one major challenge has been trying to understand all the physics of a fault–both during an earthquake and at times of "rest"–in order to know more about how a particular region may behave in the future. Now, researchers at the California Institute of Technology (Caltech) have developed the first computer model of an earthquake-producing fault segment that reproduces, in a...

Natural disasters like earthquakes and tsunamis are expected to have substantial ecological effects, but if researchers don't have enough data about the environment before the disaster strikes, as is usually the case, it is difficult to quantify these repercussions. The 2010 earthquake and subsequent tsunami in Chile is a rare exception to this trend, and researchers were able to conduct an unprecedented report of its ecological implications based on data collected on coastal ecosystems...

For submarine earthquakes that can generate tsunamis, the warning time for nearby coastal areas is very short. Using high-precision analysis of GPS data from the Fukushima earthquake of 11 March 2011, scientists at the German Research Centre for Geosciences GFZ showed that, in principle, the earthquake magnitude and the spatial distribution can be determined in just over three minutes, allowing for a rapid and detailed tsunami early warning. One advantage of a GPS monitoring network in the...

GPS Monitoring System For Big US Earthquakes To Undergo Testing
2012-04-25 04:36:04

The space-based technology that lets GPS-equipped motorists constantly update their precise location will undergo a major test of its ability to rapidly pinpoint the location and magnitude of strong earthquakes across the western United States. Results from the new Real-time Earthquake Analysis for Disaster (READI) Mitigation Network soon could be used to assist prompt disaster response and more accurate tsunami warnings. The new research network builds on decades of technology development...

German researcher presents new research at SSA Annual Meeting In the winter of 479 B.C., a tsunami was the savior of Potidaea, drowning hundreds of Persian invaders as they lay siege to the ancient Greek village. New geological evidence suggests that the region may still be vulnerable to tsunami events, according to Klaus Reicherter of Aachen University in Germany and his colleagues. The Greek historian Herodotus described the strange retreat of the tide and massive waves at Potidaea,...

Pacific Ring of Fire
2013-02-19 13:18:27

The Pacific Ring of Fire, or Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 25,000 mile horseshoe shape, it’s associated with an almost continuous series of oceanic trenches, volcanic belts, volcanic arcs and/or plate movement. The Ring of Fire contains 452 volcanoes and is home to over 75 percent of the world’s active and dormant volcanoes. It’s sometimes called the circum-Pacific belt or the...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...
