“The chance transit of a satellite over the April 2009 eruption of Fernandina volcano — the most active in South America’s famed Galápagos archipelago — has revealed for the first time the mechanism behind the characteristic pattern of eruptive fissures on the island chain’s volcanoes.” Quoted from the USGS Newsroom.
“It rains more in the Northern Hemisphere because it’s warmer,” said corresponding author Dargan Frierson, a UW associate professor of atmospheric sciences. “The question is: What makes the Northern Hemisphere warmer? And we’ve found that it’s the ocean circulation.” Quoted from the University of Washington press release.
“Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a particular area. Now, a University of Missouri researcher has found that the temperature of the Pacific Ocean could help scientists predict the type and location of tornado activity in the U.S.” Quoted from the University of Missouri press release.
“A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometers (378 miles), the intense pressure on the fault should inhibit the kind of rupture that took place.” Quoted from the University of California Santa Cruz 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.
An interesting website is “Adrift” (Adrift.org.au). On this site you can click on a point in the ocean and a computer model will map the direction that floating debris would travel – both forward in time and backwards.
“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.
Researchers have discovered evidence of life 500 meters below the seafloor of the Juan de Fuca Ridge. “They found genetic evidence of Methanosarcinales, anaerobic archaea known to metabolize methane. Further experiments showed that microbes have affected the chemical signature of sulfur in the host basalt, suggesting they could harness energy from the breakdown of sulfates.” Quoted from the Deep Carbon Observatory 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.
Methane hydrate is the world’s largest natural gas resource. Japanese engineers recently became the first to produce methane hydrate from a well in the floor of the Pacific Ocean. NPR asks if this could become another natural gas boom?
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.
