Is this where the expected Marmara earthquake will originate from? Earthquake researchers have now identified a 30 kilometers long and ten kilometers deep area along the North Anatolian fault zone just south of Istanbul that could be the starting point for a strong earthquake. The group of seismologists including Professor Marco Bohnhoff of the GFZ German Research Centre for Geosciences reported in the current online issue of the scientific journal Nature (Nature Communications, DOI:...

Megathrust Earthquakes
2013-06-13 05:25:12

redOrbit Staff & Wire Reports - Your Universe Online In an attempt to better prepare for future massive “megathrust” earthquakes along the west coast of Canada, researchers have prepared a record of earthquake history in southern British Columbia. Their findings, which were published Wednesday in the Canadian Journal of Earth Sciences, will play an important role in helping scientists, government officials and the general public understand the size and frequency of...

Mudlsides occur in every state throughout the year. A water damage restoration provider explains what causes them and how they can be avoided. Cleveland OH (PRWEB) June 07, 2013 Restoration Local, one of the leading providers of water damage repair and restoration in the United States, is offering tips to property owners on protection against mudslides. Like floods, mudslides occur across the country and any time of year, and may pose serious threats to those caught in their path....

Earthquake Sounds Help Predict Tsunamis
2013-06-07 11:27:11

Brett Smith for redOrbit.com - Your Universe Online While seismologists have the ability to detect undersea earthquakes, they don´t know which ones will turn into tsunamis. Some ocean-based sensors are able to detect an approaching tsunami, but they can only provide a few minutes of advanced warning. According to a new report in The“¯Bulletin of the Seismological Society of America, two Stanford University researchers have identified key acoustic characteristics of the...

'Caldas Tear' Resolves Seismic Activity Beneath Colombia
2013-06-06 20:49:15

Seismological Society of America Colombia sits atop a complex geological area where three tectonic plates are interacting, producing seismicity patterns that have puzzled seismologists for years. Now seismologists have identified the "Caldas tear," which is a break in a slab that separates two subducting plates and accounts for curious features, including a "nest" of seismic activity beneath east-central Colombia and high grade mineral deposits on the surface. In a paper published in...

Slow Earthquakes On San Andreas Fault Explained
2013-06-03 19:31:54

Woods Hole Oceanographic Institution New Zealand´s geologic hazards agency reported this week an ongoing, “silent” earthquake that began in January is still going strong. Though it is releasing the energy equivalent of a 7.0 earthquake, New Zealanders can´t feel it because its energy is being released over a long period of time, therefore slow, rather than a few short seconds. These so-called “slow slip events” are common at subduction zone faults...

Slow Earthquakes Take Weeks To Occur
2013-05-21 05:00:17

Lee Rannals for redOrbit.com - Your Universe Online Researchers have been aware of slow earthquakes for only the past decade, but little has been understood about them. However, new tools may help explain what triggers these quakes. Scientists thought slow earthquakes were related to the type of rock in the fault, believing that clay minerals are important in slip behavior. A team writing in the journal Nature Geoscience performed laboratory experiments using natural samples taken where...

Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in just a few minutes after the earthquake onset. For the devastating Japan 2011 event, the team reveals that the analysis of the GPS data and issue of a detailed tsunami alert would have taken no more than three minutes. The results are published on 17 May in Natural Hazards and Earth System...

Fossils Help Researchers Learn More About Cascadia Quake Of 1700
2013-05-15 18:17:53

Brett Smith for redOrbit.com — Your Universe Online Scientists have long been baffled by a massive earthquake that struck the western coast of North America in 1700. Since that part of the continent was only sparsely populated by indigenous peoples, the lack of official records has made studying the event quite difficult. According to a new report in the Journal of Geophysical Research: Solid Earth, a research team from the University of Pennsylvania has discovered new details...

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.
