University of Rochester The 1500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland—except for a curious bend in Pennsylvania and New York State. Researchers from the College of New Jersey and the University of Rochester now know what caused that bend—a dense, underground block of rigid, volcanic rock forced the chain to shift eastward as it was forming millions of years ago. According to Cindy Ebinger, a professor of earth and...

Lee Rannals for redOrbit.com - Your Universe Online A new study published in the journal Science reveals new information about the forces behind earthquakes. Geoscientists from the University of California, Los Angeles used a technique known as seismic tomography to study the structure of the Pacific Plate. This technique helped the team determine the plate’s thickness and image the interior of the plate and the underlying mantle, which they were able to relate to the direction of...

Los Angeles Earthquake Risks Studied Using 'Virtual Earthquake' Technique
2014-01-24 04:52:49

[ Watch the Video: Forecasting Los Angeles Earthquakes ] redOrbit Staff & Wire Reports - Your Universe Online A new technique developed by scientists at California’s Stanford University has confirmed that the Los Angeles would experience stronger-than-anticipated ground movement should major seismic activity occur to the city’s south, according to research published in the latest edition of Science. The method used weak vibrations generated by the Earth’s oceans to produce...

American Heartland At High Risk For Sizable Earthquakes

[ Watch the Video: Earthquake Risks In America's Heartland ] Lawrence LeBlond for redOrbit.com - Your Universe Online An earthquake zone that extends from Marked Tree, Arkansas to Paducah, Kentucky and as far south as Memphis, Tennessee has a higher earthquake risk than adjacent areas within the United States, according to new research from the US Geological Survey (USGS). Using sophisticated technology, USGS scientists have developed new high-resolution images of the New Madrid...

Superstorm Sandy Made A Seismic Impact, Shaking Up North America
2013-04-19 07:32:22

Lawrence LeBlond for redOrbit.com - Your Universe Online There´s no doubt that last autumn´s superstorm Sandy left a trail of destruction as it churned up the eastern seaboard, making a bulls-eye run at New York City. But a new study from researchers at the University of Utah has found that the storm also shook things up a bit. When Sandy took a left turn for Long Island and NYC, powerful ocean waves began slamming into each other and battered the coastline, sending...

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...

Technique provides insight into ancient formation of underwater plateau Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated by earthquakes or man-made explosions. A University of Rhode Island graduate student is using the tiny seismic waves created by ocean waves crashing on shorelines around the world to learn how an...

NASA Software Award Won By QuakeSim And NASA Mobile App
2012-09-21 14:36:26

NASA software that models the behavior of earthquake faults to improve earthquake forecasting and our understanding of earthquake processes, and NASA's first mobile application are co-winners of NASA's 2012 Software of the Year Award. The award recognizes innovative software technologies that significantly improve the agency's exploration of space and maximize scientific discovery on Earth. QuakeSim, developed at NASA's Jet Propulsion Laboratory in Pasadena, Calif., is a comprehensive,...

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,...
