Space Seismometer Recorded Japan's 2011 Earthquake, Two Years Ago Today
2013-03-11 14:58:19

WATCH VIDEO: [Earthquake Sensed By GOCE] Lee Rannals for redOrbit.com — Your Universe Online Two years ago today, Japan was rocked by a 9.0-magnitude earthquake and giant tsunami that caused both death and destruction throughout the country. Now, with instrument's like the European Space Agency's (ESA) GOCE satellite, scientists will be able to understand a bit more about these devastating quakes and how they rock Earth. ESA launched the hyper-sensitive GOCE gravity satellite...

Waves Generated By Russian Meteor Recorded Crossing The US
2013-03-07 13:29:53

National Science Foundation A network of seismographic stations recorded spectacular signals from the blast waves of the meteor that landed near Chelyabinsk, Russia, as the waves crossed the United States. The National Science Foundation- (NSF) supported stations are used to study earthquakes and the Earth's deep interior. While thousands of earthquakes around the globe are recorded by seismometers in these stations--part of the permanent Global Seismographic Network (GSN) and...

When Tsunamis Break All The Rules
2013-03-07 05:04:34

[ Watch the Video: Animation of a Tsunami Wave ] April Flowers for redOrbit.com - Your Universe Online An international collaboration has resulted in a new study showing that the earthquake zones off certain coasts, such as Japan and Java, make them especially vulnerable to tsunamis. These zones can produce a focusing point that creates massive and devastating tsunamis capable of breaking the rules by which scientists used to think tsunamis worked. Previously, scientists largely...

Japan Earthquake Produced Largest Slip Ever Recorded
2013-02-08 05:47:23

Alan McStravick for redOrbit.com - Your Universe Online As we are quickly approaching the two-year anniversary of the Tohoku-Oki earthquake that prompted the devastating Honshu tsunami, we learned this week about a rapid-response drilling operation at the site of the earthquake. The March 2011 earthquake, a magnitude 9.0 temblor, was responsible for producing a 164-foot-tall slip along the fault. This is the single largest slip ever recorded in an earthquake. Needless to say, such a...

Powerful 8.0 Magnitude Earthquake Strikes Solomon Islands, Triggers Deadly Tsunami
2013-02-06 07:00:15

Lee Rannals for redOrbit.com — Your Universe Online Villages on the Solomon Islands were struck by an 8.0 magnitude earthquake Wednesday, triggering a deadly tsunami that has taken the lives of at least six people, according to the latest estimates. Coastal Pacific communities as far away as Hawaii and Australia were also on high alert following the temblor yesterday afternoon. The Pacific Tsunami Warning Center (PTWC) said that a small tsunami wave reached part of the Solomon...

San Andreas Fault Wouldn't Stop Statewide California Quake
2013-01-12 07:54:47

redOrbit Staff & Wire Reports — Your Universe Online Assumptions that the San Andreas Fault would automatically prevent an earthquake from affecting both northern and southern California at the same time may not necessarily be true, according to a new study published Wednesday in the online edition of the journal Nature. According to Eryn Brown of the Los Angeles Times, geologists have assumed for several years that the fault line would act as a barrier, preventing seismic...

Tsunami Warning Cancelled After Earthquake Off Alaska Coast
2013-01-06 05:09:45

redOrbit Staff & Wire Reports - Your Universe Online Residents of Alaska and parts of Canada were briefly under a tsunami warning on Saturday after a strong earthquake rocked the region, but the alert was later cancelled because no potentially destructive waves resulted from the trembler. According to the United States Geological Survey (USGS), the magnitude 7.5 seismic event took place approximately 58 miles west of Craig, Alaska at approximately midnight local time (08:58:19 UTC)....

Himalayas Will Have More Massive Earthquakes, Warn Scientists
2012-12-31 11:33:53

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has found that a pair of massive, historical earthquakes ruptured the surface in the central Himalayas–leading them to theorize that similar quakes will threaten the region´s population in the future. According to the team´s report in Nature Geosciences, the two quakes, in 1255 and 1934, measured between 8 and 8.5 magnitudes on the Richter scale and both left distinct scars in...

A research team led by scientists from Nanyang Technological University (NTU) has discovered that massive earthquakes in the range of 8 to 8.5 magnitudes on the Richter scale have left clear ground scars in the central Himalayas. This ground-breaking discovery has huge implications for the area along the front of the Himalayan Mountains, given that the region has a population density similar to that of New York City. NTU Professor Paul Tapponnier, who is recognized as a leading...

A new look at the science of plate tectonics Saint Cloud, Fla. (PRWEB) December 17, 2012 “When plate tectonics is viewed as a cycle, it can be imagined to start and restart with eruptions at the earth´s ride and rise system,” explains author and professor John H. Carman. To help explain to readers this geological occurrence, Carman pens his new book, “How the Earth's Plate Tectonic Cycle Works: CMB Reaction” In his new book, Carman offers a new thesis in the...

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...
