Engineers and city planners study surface geology in order to construct buildings that can respond safely to earthquakes. Soft soil amplifies seismic waves, resulting in stronger ground motion than for sites built over bedrock. This study examines the local site response for the city of Ottawa, and the results indicate seismic waves may amplify ground motion greater than expected or referenced in the National Building Code of Canada. Current knowledge of the earthquake activity in Ottawa...

NASA Software Award Won By QuakeSim And NASA Mobile App

redOrbit Staff & Wire Reports A trio of earthquakes that stuck Central and Southern California on Friday morning caused no damage and were apparently unrelated, according to various reports published over the weekend. According to Associated Press reports, a pair of earthquakes hit the Central Valley on Friday morning. The first was magnitude 4.0 and hit at 6:22 a.m. approximately six miles southeast of the city of Huron, while the second was a magnitude 4.1 quake at the same...

Lee Rannals for redOrbit.com — Your Universe Online Scientists are reviving a century old Tesla experiment by trying to recreate an earthquake through laboratory means. Nikola Tesla tried recreating earthquakes with his electro-mechanical oscillator, or "earthquake machine," back in 1898. He attached the device to building structures in a laboratory on Houston Street in New York. According to legend, the machine shook not only his building, but neighboring structures, leading...

Want To Host A Seismograph In Your Home? Become A NetQuaker

Lee Rannals for redOrbit.com — Your Universe Online As this weekend's earthquakes still captivate the headlines, a new program is emerging that implores citizens to act as scientists to try and predict the next big quake. The program, called NetQuakes, is a crowdsourcing earthquake-monitoring program where ordinary people volunteer to help monitor quakes. The grassroots movement uses volunteers to act as hosts for one of the program's blue seismometers. NetQuake is an effort...

Lawrence LeBlond for redOrbit.com - Your Universe Online UPDATE : 08-27-2012 10:00 a.m. (EST) Latest reports on the swarm of Southern California earthquakes puts the number at somewhere around 300, according to the USGS. The continuing series of temblors produced only minor damage, knocking trailers off their foundations and breaking windows. A few reports of cosmetic damage has also been reported on some older buildings. Most of the quakes were in the range of magnitude of 3.0,...

Brett Smith for redOrbit.com — Your Universe Online Glaciologists from Pennsylvania State University and Washington University said their recent study on the David Glacier that appeared in Nature Geoscience not only provides a window into the behavior of glaciers–it also could be used as a simple model for the mechanism behind slip-stick earthquakes like those that occur in Haiti or along the San Andreas Fault. From 2002 to 2003, the research team recorded over 20,000...

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...
