Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. A seismometer is an instrument that records the shaking of the Earth's surface caused by seismic ...

They detect seismic waves and magnify ground movement by mechanical, electronic, electromagnetic, or mechanical-optical methods. Seismometer outputs are transmitted to seismographs, seismic ...

The latest on the restoration efforts from BC Hydro can be found here. Seismographs are designed to detect vibrations caused ...

Anything that produces ground vibrations can be recorded. For example, cars on I-90 and I-95/Rt. 128 (especially during rush hour) cause slight vibrations in the ground that our seismometers record ...

Distances from the stations to the earthquake are estimated from the difference between P and S wave arrival times: You have just figured out how far your seismograph is from the epicenter and how ...

[10DotMatrix] has a budding interest in seismology, so she decided to make her own seismometer out of some easy-to-find materials. Seismometers are prohibitively expensive for hobbyists ...

A network of seismometers is operated and maintained by the Earthquake Center, which is part of a regional network to monitor seismicity of the New Madrid seismic zone and a global network to monitor ...

An ocean bottom seismometer being retrieved after spending 10 months on the floor of the Pacific Ocean to map the mantle 100 miles underneath the Juan de Fuca plate. Disclaimer: AAAS and EurekAlert!

Scripps researchers develop and operate long-term global and regional observing systems that improve understanding of environmental change and hazards such as earthquakes, tsunamis, hurricanes, ...

The animation shows a network of North American seismometers lighting up as the ... the ionosphere and change its refractive index. RF-Seismograph trace from the time of the Turkey-Syria quake.

Twelve skeletons have been found in a large, 2,000-year-old tomb directly in front of the Khazneh ("Treasury") in the city of Petra in Jordan. Alongside them, excavators have discovered grave ...
