A new method of monitoring earthquakes allows scientists to better understand the behavior of deep tremors, Scottish researchers said. By studying seismic waves from separate earthquakes, scientists at the University of Edinburgh were able to measure tremors deeper in the Earth than they could with a seismometer, which measures motion on the Earth's surface, Edinburgh geoscientist Andrew Curtis said. By using earthquakes themselves as virtual microphones that record the sound of the Earth's...

University of Utah scientists devised a new way to find miners trapped by cave-ins. The method involves installing iron plates and sledgehammers at regular intervals inside mines, and sensitive listening devices on the ground overhead. "We developed an approach to find the location of trapped miners inside a collapsed mine, regardless of noise from the environment around the mine," says Sherif Hanafy, an adjunct associate professor of geology and geophysics at the University of Utah and first...

A newly laid, 32-mile underwater cable finally links the state's only seafloor seismic station with the University of California, Berkeley's seismic network, merging real-time data from west of the San Andreas fault with data from 31 other land stations sprinkled around Northern and Central California. Laying of the MARS (Monterey Accelerated Research System) fiber-optic cable was completed in 2007 by the Monterey Bay Aquarium Research Institute (MBARI) to power and collect data from a...

Dull science classes will be transformed into earth-moving lessons for schoolchildren across Devon and Cornwall thanks to a new initiative launched by Westcountry university. Fourteen schools are to be provided with earthquake-monitoring seismometers as part of Plymouth University's regional involvement in the British Geological Survey project. They will be able to use the instruments to record and analyse ground movement data, place the information on the British Geographical Survey...

Scientists are turning to the public to help document earthquakes and identify areas of potential damage.  The new initiative, called the Quake-Catcher Network, was launched earlier this year, and aims to harness the computing power of roughly 300 global participants worldwide, including 50 in California.   Experts would equip volunteers' laptop computers and homes with special software and quake sensors.  Almost anyone with a laptop or a little extra space in his or her...

By Julia Scott PORTOLA VALLEY -- When you live on the San Andreas fault line, as all Portola Valley residents do, earthquake science is taught in school and geologists lead expeditions through town. It was only a matter of time before residents built their own seismograph to measure tremors under their feet. It may not look like much, but the seismograph in question -- a deceptively simple collection of wire-suspended pendulums, magnets and coils -- will be able to sense earthquakes as...

Stick, slip, like an earthquakeA seismologist at Washington University in St. Louis and colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that makes California's earthquake problem seem trivial.Douglas A. Wiens, Ph.D., Washington University professor of earth and planetary sciences in Arts & Sciences, and colleagues combined seismological and global positioning system (GPS) analyses...

Scientists at the University of Washington (UW) in Seattle said Wednesday that a meteor many witnesses saw shooting across the sky on Tuesday morning had likely disintegrated and not struck the Earth. Witnesses from Washington, Oregon, Idaho, Montana and British Columbia had reported seeing the meteor around 5:30 a.m. Tuesday.  Local officials in central Washington were dispatched after some of the witnesses said the meteor had hit the ground southwest of Ritzville.   ...

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...
