Want To Host A Seismograph In Your Home? Become A NetQuaker
2012-08-27 15:24:47

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...

Arizona Earthquakes Not As Rare As Once Thought
2012-08-15 08:40:27

April Flowers for redOrbit.com - Your Universe Online Earthquakes are a scary phenomenon. They are enormously destructive and much more common than you might think. Several million earthquakes are estimated to occur worldwide each year. Most are too small to feel, but they can be measured by arrays of seismometers. Some are so large they claim hundreds of thousands of lives (Shaanxi China, 1556, claimed 830,000 lives) while some create massive economic hardship (San Francisco, USA,...

Mars Joins Earth As Only Planets Known To Have Plate Tectonics
2012-08-10 07:07:00

[ Video 1 ] | [ Video 2 ] Lawrence LeBlond for redOrbit.com - Your Universe Online For decades, scientists thought the only place in our solar system that consisted of plate tectonics was right here on Earth. But a UCLA scientist has discovered, analyzing data from two instruments, that the Red Planet has also shown evidence of tectonic plate movement. The science of plate tectonics revolves around the idea that huge crustal plates beneath a planet´s surface are constantly...

On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be connected with processes in the mantle. These are the research results presented by a group of geoscientists in the new advance edition of "Nature Geoscience" on Sunday, July 29th. The results show how the rapid processes in the outer core, which flows at rates of up to about one millimeter per...

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...
