New Study Reveals Quake-triggered Landslides Pose Significant Hazard For Seattle
2013-10-22 13:40:44

Seismological Society of America A new study suggests the next big quake on the Seattle fault may cause devastating damage from landslides, greater than previously thought and beyond the areas currently defined as prone to landslides. Published online Oct. 22 by the Bulletin of the Seismological Society of America (BSSA), the research offers a framework for simulating hundreds of earthquake scenarios for the Seattle area. "A major quake along the Seattle fault is among the worst case...

American Heartland At High Risk For Sizable Earthquakes
2013-09-30 14:15:26

[ 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...

Hundreds Feared Dead After 7.7 Magnitude Quake Rocks Pakistan
2013-09-25 06:57:07

Lawrence LeBlond for redOrbit.com - Your Universe Online A massive earthquake measuring 7.7 on the Richter scale struck 13 miles northeast of Awaran, Pakistan on Tuesday afternoon at 4:29 p.m. (local time), according to the US Geological Survey (USGS). The temblor was felt across the country and has killed at least 200 people; various media reports have so far put the death toll at between 200 and 250, nearly all from the remote southwest province of Baluchistan, the country’s...

Scientists broke new ground in the study of deep earthquakes, a poorly understood phenomenon that occurs where the oceanic lithosphere, driven by tectonics, plunges under continental plates – examples are off the coasts of the western United States, Russia and Japan. This research is a large step toward replicating the full power of these earthquakes to learn what sets them off and how they unleash their violence. It was made possible only by the construction of a one-of-a-kind X-ray...

Earthquake Deep Below Sea Of Okhotsk Has Scientists Puzzled
2013-09-20 04:06:10

redOrbit Staff & Wire Reports - Your Universe Online Scientists know that on May 24, 2013, a magnitude 8.3 earthquake occurred beneath the Sea of Okhotsk off the coast of Russia. What they don’t know is how or why it happened. The earthquake occurred at a depth of approximately 378 miles (609 kilometers). However, according to Thorne Lay, professor of Earth and planetary sciences at the University of California, Santa Cruz (UCSC), and his colleagues, the intense pressure on the...

Newly Discovered Seismic Waves Reveal Earth's Volcanic Hotspots
2013-09-06 08:40:14

April Flowers for redOrbit.com - Your Universe Online A previously unknown channel of slow-moving seismic waves in the Earth’s mantle has been discovered by a team of scientists from the University of California, Berkeley and the University of Maryland. These waves help to explain "hotspot volcanoes" that give birth to island chains such as Hawaii and Tahiti. The findings of this study have been published in Science Express. Hotspot volcanoes form in the middle of tectonic plates,...

National Preparedness Month: USGS Helping People Prepare For Natural Hazards
2013-08-30 06:51:14

Lawrence LeBlond for redOrbit.com - Your Universe Online As National Preparedness Month begins, it may be a good time to reflect on the threats we face around us, including damaging hurricanes, devastating wildfires, extreme heat waves and severe drought, among others. To help keep us informed, the US Geological Survey (USGS) is planning to bring daily content in the form of preparedness information, posted over social media channels, alerting of the dangers we face and how to best...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
