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.
A study published in Nature Communications suggests the cumulative stresses caused by historic earthquakes could provide some explanation as to why and where they occur. The research involved a detailed analysis of centuries of earthquakes in central Italy, where unrivaled records of seismic events have been kept since 1349.
The quest to discover what drove one of the most important evolutionary events in the history of life on Earth has taken a new, fascinating twist.
There are two competing ideas of how platinum deposits formed: the first involves gravity-induced settling of crystals on the chamber floor, while the second idea implies that the crystals grow in situ, directly on the floor of the magmatic chamber. Researchers have established that the crystals grow in situ, with its high platinum status being attained while all its minerals were crystallising along the cooling margins of the magma chamber.
The unusual appearance of deep-sea fish like the oarfish or slender ribbonfish in Japanese shallow waters does not mean that an earthquake is about to occur, according to a new statistical analysis.
