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...

Geoelectrrical analysis and the change between creep and quakes in the San Andreas fault Geophysicists from Potsdam have established a mode of action that can explain the irregular distribution of strong earthquakes at the San Andreas Fault in California. As the science magazine Nature reports in its latest issue, the scientists examined the electrical conductivity of the rocks at great depths, which is closely related to the water content within the rocks. From the pattern of electrical...

New Zealand: After 8,000 aftershocks, when will it stop? "You know you are from Christchurch when“¦" you manage to keep your sense of humor through a year of nonstop hardship. This phrase, coined by Christchurch native Bruce Raines, exploded on Facebook and takes on a multitude of equally morose and light-hearted endings. These phrases accurately capture the spirit of the local inhabitants after a series of earthquakes and aftershocks rocked the city, dramatically changing...

Earthquakes Have Largest Impact On Health Than Other Natural Disasters
2011-11-04 11:38:33

Researchers say that earthquakes have a bigger impact on health than other natural disasters like floods and hurricanes. The researchers said earthquakes have caused over 780,000 deaths in the past decade.  They also said that for every person killed in an earthquake, three others are injured. There are over a million earthquakes around the world each year, and many of the world's major cities are on fault lines. The team said that depression can be the most common problem after...

Special issue of Seismological Research Letters Details of an earthquake that rocked the largest city in the South Island of New Zealand in February 2011 may transform the way scientists assess the potential threat of fault lines that run through urban centers. According to a series of new papers published today in Seismological Research Letters (SRL), scientists were surprised at the impact of the earthquake, which registered a relatively moderate magnitude 6.2. The in-depth review of...

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...
