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...

Powerful Earthquake Shakes Pacific 110 Miles From El Salvador

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful 7.3 magnitude earthquake struck off the coast of El Salvador Sunday night, followed by a 5.4 magnitude aftershock an hour later, according to a report by the US Geological Survey. The quake´s epicenter was about 110 miles southeast of the capital San Salvador, and was located about 33 miles underground. Following the temblor, the Pacific Tsunami Warning Center issued an alert, saying the quake had spawned a...

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,...

Lawrence LeBlond for redOrbit.com - Your Universe Online Why do some tsunamis, such as the devastating one that struck Japan in March 2011, occur on a much larger scale than scientists expect? The answer, based on a model developed by researchers at the University of Cambridge, lies within the “pop-up” movement of large amounts of sediment. Undersea earthquakes can release huge amounts of energy as tectonic plates slip across each other´s ridge lines. A study in Earth...

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...

New Insights Into The Strength Of Continents

April Flowers for redOrbit.com - Your Universe Online Over the last 50 million years, the Caribbean islands have been pushed east, driven by the movement of the Earth's viscous mantel against the more rooted South American continent. A new study by University of Southern California (USC) geophysicists, published in Nature Geoscience, gives us a better understanding of how continents resist the constant movement of the Earth's plates and what effect the continental plates have in...

[ Watch the Video ] Brett Smith for redOrbit.com - Your Universe Online A new study by researchers at Durham University in the United Kingdom asserts that landslide deaths have been underestimated by tenfold. The result of their research has been compiled in a new database, the Durham Fatal Landslide Database (DFLD), which shows that 32,000 people died in landslides between 2004 and 2010. Previous estimates pegged the range of fatalities at 3,000 to 7,000. According to their...

A team of researchers may have discovered a way to hear earthquakes. Not the noises of rattling windows and crumbling buildings, but the real sounds an earthquake makes deep underground as rock grinds and fails catastrophically. Typical seismic waves have frequencies below the audible range for humans, but the August issue of EARTH shows you where to find the voice of one seismic monster: the March 11, 2011, magnitude-9.0 Tohoku earthquake in Japan. Beyond the novelty of simply hearing an...

Pacific Ring of Fire
2013-02-19 13:18:27

The Pacific Ring of Fire, or Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 25,000 mile horseshoe shape, it’s associated with an almost continuous series of oceanic trenches, volcanic belts, volcanic arcs and/or plate movement. The Ring of Fire contains 452 volcanoes and is home to over 75 percent of the world’s active and dormant volcanoes. It’s sometimes called the circum-Pacific belt or the...

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...
