The Physics Of Earthquake Forecasting
2012-03-02 03:42:50

One year on from the magnitude-9.0 earthquake that unleashed a devastating tsunami and caused a partial meltdown of the Fukushima Daiichi nuclear plant, this month's special issue of Physics World, on the theme of "Physics and the Earth", includes an investigation by journalist Edwin Cartlidge into the latest advances in earthquake forecasting. In addition to the special issue, physicsworld.com hosts an exclusive video documentary reviewing the fundamental science behind earthquakes and...

Image 1 - First EarthScope 'Transportable Array' Seismic Station Reaches US East Coast
2012-02-18 04:35:13

Data generate 3-D 'CT scan' of North American continent's interior Yulee, Florida. Not a place one usually thinks of as an Earthquake Epicenter. But this swampland not far from the Georgia state line is now home to a state-of-the-art seismic station known as 457A. Here, within a few miles of the Atlantic Ocean, 457A has been installed to record ground motion from earthquakes. Earthquakes do happen on the East Coast of the United States, as the Virginia quake of August, 2011 attests....

Image 1 - Fukushima Still Faces Earthquake Risk
2012-02-14 12:04:46

Seismic risk at the Fukushima nuclear plant increased after the magnitude 9 earthquake that hit Japan last March, scientists report. The new study, which uses data from over 6,000 earthquakes, shows the 11 March tremor caused a seismic fault close to the nuclear plant to reactivate. The results are now published in Solid Earth, an open-access journal of the European Geosciences Union (EGU). The research suggests authorities should strengthen the security of the Fukushima Daiichi nuclear...

Image 1 - 3D Imaging Technology Could Help Multi-Fault Earthquake Preparations
2012-02-10 06:19:20

[ Watch the Video ] A team of U.S., Mexican, and Chinese geologists have used a new tool to help pinpoint the precise locations where earthquakes caused the planet's crust to rupture and alter the landscape, resulting in what they are calling the "most comprehensive before-and-after picture“¦ of an earthquake zone to date." The 3D images, which were published in the February 10 issue of the journal Science, were captured from a 7.2. magnitude earthquake that occurred near...

Philippines Struck By 6.9 Magnitude Earthquake
2012-02-06 12:47:32

A 6.9 magnitude earthquake struck the Philippines on Monday morning, killing at least 13 people and leaving dozens trapped under houses and buildings. Governor Roel Demago said that as many as 30 houses were buried with at least 40 residents in the mountain village of Planas. "Their situation is bad because if you are covered by landslide for one hour, two hours, how can you breathe?" Mayor Ernesto Reyes said in a statement. "But we just hope for the best, that there are still...

Tokyo Has Chance of Seeing Magnitude 7 Earthquake In The Near Future
2012-01-25 10:13:29

Japan´s capital city, Tokyo, has a high probability of experiencing a magnitude-7 earthquake within just a few years, according to Japanese scientists. Researchers at the University of Tokyo´s Earthquake Research Institute announced Monday there was a 75 percent chance that a 7.0 magnitude quake could strike the region within four years, and a 98 percent probability of one striking in the next 30 years. The announcement coincided a magnitude 5.1 quake that rocked large parts...

CEDIM publishes 2011 Damage Report — considerable economic losses Last year, earthquakes and their consequences, such as tsunamis, landslides, and ground settlements, caused a damage of 365 billion US dollars. Hence, 2011 was the year with the so far highest economic losses due to earthquakes. This is the result of an analysis submitted by James Daniell from the Center for Disaster Management and Risk Reduction Technology (CEDIM) of Karlsruhe Institute of Technology (KIT). According...

Ohio Officials Suspend Fracking Operations At Well
2012-01-05 05:57:26

Ohio officials said Tuesday that the state has suspended operations at a well used to dispose of waste water from "fracking". The suspension comes after suspicion that disposal of waste water by reinjecting it into the ground may have triggered seismic activity. The latest earthquake measured 4.0 on New Year's Eve and was near the well operated by D&L Energy in Youngstown. The state shut down operations at the Youngstown injection well after a 2.7 magnitude quake on December 24....

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...
