Forty-two percent of those surveyed named older adults as the most at risk of fire danger. Bethesda, MD (PRWEB) February 20, 2014 Older adults are more vulnerable to a number of risks including fire, either at home or in assisted living facilities such as nursing homes. In a recent survey conducted by the Society for Fire Protection Engineers (SFPE), people correctly identified adults age 65 and older as the most at-risk group. Forty-two percent of those surveyed named older adults as...

Instead of winging it, planners need to think carefully about costs and benefits The dramatic images of natural disasters in recent years, including hurricanes Katrina and Sandy and the Tohoku, Japan, earthquake and tsunami, show that nature, not the people preparing for hazards, often wins the high-stakes game of chance. "We're playing a high-stakes game against nature without thinking about what we're doing," geophysicist Seth Stein of Northwestern University said. "We're mostly...

San Francisco's 'Big One' In 1906 Was Third In A Series Of Quakes
2014-02-13 06:31:07

April Flowers for redOrbit.com - Your Universe Online Geologic evidence that supports historical narratives for two earthquakes in the 68 years prior to the 1906 quake that devastated San Francisco has been discovered by a research team led by the University of Oregon. The evidence, discovered by doctoral student Ashley R. Streig, places the two earthquakes—in 1838 and 1890—on the San Andreas Fault. Previously, many researchers had theorized this placement based on written accounts...

Latest ETV video features earthquake-resistant building, which literally rocks. San Francisco, CA (PRWEB) January 28, 2014 Sitting virtually astride California's infamous San Andreas Fault – the tectonic boundary between two massive geologic plates, the North American and the Pacific – San Francisco is no stranger to earthquakes. The City by The Bay and its surrounding communities were struck twice during the last century. The first one, in 1906, nearly destroyed the city...

Oceans Earths Mantle

Lee Rannals for redOrbit.com - Your Universe Online University of Liverpool scientists believe that up to three and a half times the water of all the Earth’s oceans could be being transported beneath our feet. Seismologists reported in the journal Geology that they found deep sea fault zones could transport much larger amounts of water from Earth’s oceans to the upper mantle than previously thought. The team analyzed earthquakes that occurred more than 60 miles below the Earth’s...

Los Angeles Earthquake Risks Studied Using 'Virtual Earthquake' Technique

[ 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...

Georgia Basin May Amplify Ground Shaking From Next Quake In Vancouver
2014-01-21 08:15:38

Seismological Society of America Tall buildings, bridges and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves passing through the Georgia basin, according to two studies published by the Bulletin of the Seismological Society of America (BSSA). The basin will have the greatest impact on ground motion passing over it from earthquakes generated south and southwest...

The Regional Intermodal Transportation Center (RITC) now under construction at Bob HopeAirport in Burbank is one of the most engineered to withstand a massive earthquake such as the6.7-magnitude quake that hit Northridge 20 years ago, reports earthquake and structural engineering firm Miyamoto International. BURBANK, California (PRWEB) January 17, 2014 Of all the buildings in the Los Angeles Basin, the Regional Intermodal Transportation Center (RITC) now under construction at Bob Hope...

NASA JPL Scientist Reflects Last Big Quake In Los Angeles
2014-01-17 09:14:01

NASA's Jet Propulsion Laboratory Twenty years ago this week, in the predawn darkness of Jan. 17, 1994, at five seconds before 4:31 a.m. PST, the ground ruptured violently on a blind thrust fault (a crack in Earth's crust that does not reach the surface) about 11 miles (18 kilometers) beneath Reseda, in California's San Fernando Valley about 20 miles (31 kilometers) northwest of downtown Los Angeles. The resulting magnitude 6.7 earthquake, known as the Northridge earthquake, became 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...
