“Global map of crustal thickness of the moon derived from gravity data obtained by NASA’s GRAIL spacecraft. The lunar near side is represented on the left hemisphere. The far side is represented in the right hemisphere.”
Ancient people carried and traded obsidian objects over wide geographic areas. Researchers have found success at attributing these artifacts with the geographic locality of an eruption by measuring their magnetic characteristics.
“Using technology found in cell phones, inexpensive sensors being tested at Monte Sano State Park might one day soon save lives by giving advance warning of deadly landslides in at-risk areas around the world.” Quoted from the University of Alabama in Huntsville 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.
“We currently don’t have any way to remotely monitor when land faults are about to move” [...] “This has the potential to change the game for earthquake monitoring and prediction, because if it is right and you can make the right predictions, it could be big.”
An article on the EarthMagazine.org website reports on the use of geophysical tools (ground penetrating radar, electrical resistivity, bulk ground conductivity, gradient magnetometry) for finding graves in Colombia.
“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.
NASA’s GRAIL mission has solved one of the mysteries of the Moon. “Why is the Moon’s gravity is uneven?… It appears that asteroid impacts have created patches of very high density rock in the subsurface.
“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 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.
“Recent airborne geophysical surveys near Decorah, Iowa are providing an unprecedented look at a 470- million-year-old meteorite crater concealed beneath bedrock and sediments. [...] The extent of the shale, which was deposited after the impact by an ancient seaway, defines a “nice circular basin” of 5.5 km width.” Quoted from the University of Iowa press release.
“Nearly three months after Tolbachik began erupting, lava continues to flow from the Kamchatkan volcano. Over time, the lava flows change location and shift across the landscape. In this image, infrared data is superimposed on a natural-color image to highlight active flows.” Quoted from the Earth Observatory image release.
“In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction.” Quoted from the NASA press release.
