A magnitude 8.2 earthquake struck off the Pacific coast of Chile at about 6:46 PM local time. An early report in the Los Angeles Times indicates building and highway damage. A tsunami warning was issued but waves observed were small. View USGS Data.
Most people know about tsunamis, but very few know about METEOtsunamis. They are not caused by earthquakes, not caused by tides and you can learn more about these large wave events in an Earth Magazine article.
“The risk posed by tsunami waves generated by Canary Island landslides may need to be re-evaluated, according to researchers at the National Oceanography Centre. Their findings suggest that these landslides result in smaller tsunami waves than previously thought by some authors, because of the processes involved.” Quoted from a National Oceanography Centre press release.
“Scientists at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., and Scripps Institution of Oceanography at UC San Diego have enhanced existing GPS technologies to develop new systems for California and elsewhere to warn of hazards from earthquakes, tsunamis and extreme weather events.” Quoted from the NASA press release.
“University at Buffalo researchers are developing a deep-sea Internet. The technological breakthrough could lead to improvements in tsunami detection, offshore oil and natural gas exploration, surveillance, pollution monitoring and other activities.” Quoted from the University at Buffalo press release.
The Spring 2013 issue of Oceanus Magazine, published by Woods Hole Oceanographic Institution, is titled Fukushima and the Ocean. It looks at the triple disaster that hit Japan with an earthquake, a tsunami and a power plant failure.
“The Science Application for Risk Reduction tsunami scenario depicts a hypothetical but plausible tsunami created by an earthquake offshore from the Alaska Peninsula and its impacts on the California coast. ” Quoted from the USGS Newsroom.
“Stanford scientists have identified key acoustic characteristics of the 2011 Japan earthquake that indicated it would cause a large tsunami. The technique could be applied worldwide to create an early warning system for massive tsunamis.” Quoted from the Stanford University press release.
“Dynamic modeling of sea-level rise, which takes storm wind and wave action into account, paints a much graver picture for some low-lying Pacific islands under climate-change scenarios than the passive computer modeling used in earlier research.” Quote from the USGS press release.
“Multinational research team finds that sea floor earthquake zones can act like a “magnifying lens,” focusing and strengthening tsunamis beyond what was through possible.” Quoted from the University of Southern California press release.
“According to a new technical report, the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities’ social, economic and natural systems. The report, Coastal Impacts, Adaptation, and Vulnerabilities: a technical input to the 2013 National Climate Assessment, authored by leading scientists and experts, emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change.” Quoted from the USGS press release.
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.
