Eleonora Rivalta and her team from the GFZ German Research Centre for Geosciences in Potsdam, together with colleagues from the University Roma Tre and the Vesuvius Observatory of the Italian Istituto Nazionale di Geofisica e Vulcanologia in Naples have devised a new method to forecast volcanic vent locations. The study is published in the journal Science Advances.
Numerical simulations have pinpointed the source of acoustic signals emitted by stressed faults in laboratory earthquake machines. The work further unpacks the physics driving geologic faults, knowledge that could one day enable accurately predicting earthquakes.
An international scientific team led by Russian geochemists have established that the huge reserves of water present in the Earth's mantle, which exceed the weight of the world ocean, emerged over 3.3 billion years ago due to the immersion of seawater-rich oceanic crust into the depth of the Earth's interior. The results were published in Nature.
The molten rock that feeds volcanoes can be stored in the Earth's crust for as long as a thousand years, a result which may help with volcanic hazard management and better forecasting of when eruptions might occur.
Earthquakes are getting deeper at the same rate as the wastewater sinks.
The discovery of Tamu Massif, a gigantic volcano located about 1,000 miles east of Japan, made big news in 2013 when researchers reported it was the largest single volcano documented on earth, roughly the size of New Mexico. New findings, reported this week in Nature Geoscience, conclude that it is a different breed of volcanic mountain than earlier thought, throwing into doubt the prior claim that it is the world's largest single volcano.
Istanbul is located in close proximity to the North Anatolian fault, a boundary between two major tectonic plates where devastating earthquakes occur frequently. Using an autonomous measuring system on the seafloor, researchers of the GEOMAR, Kiel, together with colleagues from France and Turkey, have now for the first time measured deformation underwater and detected a considerable build-up of tectonic strain below the Marmara Sea near Istanbul.
A new radioactivity model of Earth's ancient rocks calls into question current models for the formation of Earth's continental crust, suggesting continents may have risen out of the sea much earlier than previously thought but were destroyed, leaving little trace.
A Stanford geophysicist discusses how the devastating 2015 Gorkha earthquake that shook Kathmandu, Nepal gave researchers new information about where, why and how earthquakes occur.
A study led by Prof. BAI Ling from the Institute of Tibetan Plateau Research (ITP) of the Chinese Academy of Sciences revealed that the rupture length of the 2015 MW 7.8 Gorkha earthquake was likely controlled by spatial (both along- and across-strike) variations in the Main Himalayan Thrust.
