Acoustic Wave Tsunami Warning System
2013-08-29 13:34:12

[ Watch the Video: What is a Tsunami? ] Peter Suciu for redOrbit.com – Your Universe Online While the waves from a tsunami can be extremely destructive, acoustic waves could help warn of the impending danger. Not much can be done to actually stop these natural disasters, but the earlier a warning goes out that a tsunami could strike the coast, the better the chances of effectively evacuating the area. Early warning systems play a critical role in ensuring that people reach safety,...

Helmholtz Association Real time observation of shear waves on the Earth's surface, first direct observation of subducting continental crust during the collision of two continents Earthquake damage to buildings is mainly due to the existing shear waves which transfer their energy during an earthquake to the houses. These shear waves are significantly influenced by the underground and the topography of the surrounding area. Detailed knowledge of the landform and the near-surface...

WorkSafe Technologies of Northern California understands Cal State's recent decision to demolish Warren Hall after being declared the most seismically unsafe structure in the university system. Hayward, CA (PRWEB) August 22, 2013 For over 20 years WorkSafe Technologies of Northern California has suggested to their customers "hope for the best, but prepare for the worst" when it comes to earthquakes. Non-structural seismic mitigation of a companies health and safety risks is...

Since records began in 1776, the people of Youngstown, Ohio had never experienced an earthquake. However, from January 2011, 109 tremors were recorded and new research in Geophysical Research-Solid Earth reveals how this may be the result of shale fracking. In December 2010, Northstar 1, a well built to pump wastewater produced by fracking in the neighboring state of Pennsylvania, came online. In the year that followed seismometers in and around Youngstown recorded 109 earthquakes; the...

Scientists at the University of Bonn simulate that seismic waves can be focused like in a parabolic reflector In 2006 the island of Java, Indonesia was struck by a devastating earthquake followed by the onset of a mud eruption to the east, flooding villages over several square kilometers and that continues to erupt today. Until now, researchers believed the earthquake was too far from the mud volcano to trigger the eruption. Geophysicists at the University of Bonn, Germany and ETH Zurich,...

Volcanoes Like To Scream Out Before They Blow Their Lids
2013-07-15 13:47:55

Brett Smith for redOrbit.com - Your Universe Online Scientists often detect a series of small earthquakes just before a volcanic eruption and a new study published in the Journal of Volcanology and Geothermal Research has shown that these tremors can happen in such a rapid succession -- that they create sound vibrations that rise in pitch until the volcano erupts. The study authors came to their conclusion by looking at the March 2009 eruption of Alaska's Redoubt Volcano, which was...

Humans Causing Seismic Activity
2013-07-12 08:57:39

Brett Smith for redOrbit.com - Your Universe Online Two studies published in the journal Science have both found human geologic activities could be causing nearby seismic activity. One study found that massive earthquakes from around the world have been triggering localized seismic events surrounding waste-fluid injection wells in the central United States. Large amounts of water are used in both hydrofracking and the more conventional mining of oil and gas from underground wells. After...

USGS is incorporating quick and inexpensive approaches to enhance earthquake research The U.S. Geological Survey (USGS) and other scientific institutions are using social media and crowdsourcing to learn more about earthquakes, according to a new report. These techniques provide inexpensive and rapid data to augment and extend the capabilities provided by traditional monitoring techniques. The new report, Transforming Earthquake Detection and Science Through Citizen Seismology, released...

Airplane Scans New Madrid For Geological Activity

Brett Smith for redOrbit.com - Your Universe Online Folks living near the Mississippi River where Arkansas, Tennessee, Missouri and Kentucky converge should expect to see a low-flying, red-and-white Cessna today. Do not be alarmed, U.S. Geological Survey officials announced. The region, known as the New Madrid seismic zone, is of particular interest to geologists and the federal agency is using low-level flights, being performed by specially trained pilots, to detect subtle local...

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...
