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

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

[ 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...

BSSA is published by the Seismological Society of America. 2010 Haiti quake possible start of new cycle of seismic activity, according to new study. The January 2010 quake that destroyed much of Port-au-Prince may have marked the start of a new cycle of active seismicity, putting Haiti and the Dominican Republic at high risk of future devastating earthquakes. The island of...

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...

Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...

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...

The Seismometer is an instrument designed to measure the motions of the ground. This includes seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of these activities allow seismologists to map the interior of the Earth, and locate and measure the size of the different sources. There are also seismographs, which is sometimes used in place of the word seismometer. However, a seismograph is the older instrument in which the measuring and recording...
