“Forecasting volcanic eruptions with success is heavily dependent on recognizing well-established patterns of pre-eruption unrest in the monitoring data. But in order to develop better monitoring procedures, it is also crucial to understand volcanic eruptions that deviate from these patterns.” Quoted from the Carnegie Institution for Science press release.
Most homeowners insurance policies have exclusions that make them worthless when the home is damaged by common geologic problems such as floods, earthquakes, landslides, mine subsidence, cavern collapse and expansive soils. When a home is damaged the homeowner often is surprised that his “all perils” policy has these exclusions.
A magnitude 6.6 earthquake in China killed over 150 people and injured more than 5,000 on Saturday morning. USGS reports that the earthquake is likely to have occurred on the Longmenshan Fault or a tectonically related fault.
“We detected seismic waves created by the oceans waves both hitting the East Coast and smashing into each other,” with the most intense seismic activity recorded when Sandy turned toward Long Island, New York and New Jersey.
“Scientists have linked a rising number of quakes in normally calm parts of Arkansas, Texas, Ohio and Colorado to below-ground injection. In the last four years, the number of quakes in the middle of the United States jumped 11-fold from the three decades prior.” Quoted from the Columbia University press release.
“Scientists at Scripps Institution of Oceanography at UC San Diego have found a layer of liquefied molten rock in Earth’s mantle that may be acting as a lubricant for the sliding motions of the planet’s massive tectonic plates.” Quoted from the Scripps press release.
“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.” Quoted from the National Science Foundation press release.
“Predicted population increases in this century can be expected to translate into more people dying from earthquakes. There will be more individual earthquakes with very large death tolls as well as more people dying during earthquakes than ever before, according to a newly published study led by U.S. Geological Survey engineering geologist Thomas L. Holzer.” Quoted from the USGS announcement.
The Department of Energy’s Geothermal Annual Report includes information about: play fairway mapping, geothermal demonstration projects, induced seismic events, the National Geothermal Data System and outreach to educational institutions.
A Magnitude 8.0 earthquake occurred in the Santa Cruz Islands area at about 8:12 PM EST. Tsunami warnings were issued for numerous islands in the South Pacific and waves up to 3 feet in amplitude have been reported.
USAToday reports that dozens of homes were damaged in the Solomon Islands.
“New Caltech research suggests creeping faults can turn destructive which could explain the unexpectedly large 2011 earthquake in Japan and give new insight on potential future quakes along the San Andreas Fault. In contrast to some current theories, the research suggests that earthquake ruptures might not stop at creeping fault segments—which are considered stable—instead activating the supposedly stable segments and triggering a bigger quake with more destructive power across a large area.” Quoted from a Caltech media release.
Did you know that the NOAA website has a tabulation of “Watches, Warnings and Advisories” for each of the 50 states? These include blizzard warnings, avalanche warnings, fire weather watches, wind advisories and much more.
“The primary goal of U.S. Geological Survey Natural Hazards Response is to ensure that the disaster response community has access to timely, accurate, and relevant geospatial products, imagery, and services during and after an emergency event. [...] Post-event imagery and analysis can provide important and timely information about the extent and severity of an event. USGS Natural Hazards Response will also support the coordination of remotely sensed data acquisitions, image distribution, and authoritative geospatial information production as required for use in disaster preparedness, response, and recovery operations.” Quoted from the USGS Fact Sheet.
“Once buried under detritus eroded from the uplifted Santa Catalina Mountains, the Pirate fault is currently being exhumed by the downcutting Cañada del Oro and its tributaries. [...] This field examination reveals the fault to have left a sparse but diverse collection of remains implying a varied history of fault development and evolution.” Quoted from the publication press release.
