According to findings published Dec. 9 in the journal Science Advances, plate subduction could have started 3.75 billion years ago, reshaping Earth's surface and setting the stage for a planet hospitable to life.
The summer 2018 eruption of K?lauea Volcano on the Island of Hawai'i was one of the most significant in the volcano's history, collapsing a large portion of the summit caldera, erupting massively from its flank and triggering a magnitude 6.9 earthquake in the process. Through it all, scientists at the Hawaiian Volcano Observatory were installing new geophysical stations, processing data and making real-time reports to local authorities and neighborhoods.
A recent study led by researchers from the Institute of Tibetan Plateau Research (ITP) of the Chinese Academy of Sciences (CAS) proves, through fossil analysis, that much of the Third Pole only grew to its modern height over the past 10 million to 20 million years, rather than 40 million years ago (Ma) as previously inferred.
A team of researchers understands more about the melting of the Greenland ice sheet. They discovered a flow of hot rocks, known as a mantle plume, rising from the core-mantle boundary beneath central Greenland that melts the ice from below.
At what depth beneath the seabed does it become so hot that microbial life is no longer possible? This question is the focus of a close scientific cooperative effort between JAMSTEC and MARUM -- Center for Marine Environmental Sciences at the University of Bremen. An expedition by the drilling program IODP in 2016 has provided new insights into the temperature limits of life beneath the ocean floor. The findings have now been published by the international team in Science.
New evidence of a 19th century earthquake on New Zealand's Alpine fault suggests that in at least one portion of the fault, smaller earthquakes may occur in between such large rupture events.
The continents will reunite again in the deep future. And a new study, presented today during an online poster session at the meeting of the American Geophysical Union, suggests that the future arrangement of this supercontinent could dramatically impact the habitability and climate stability of Earth. The findings also have implications for searching for life on other planets.
What if there is a major earthquake near Cologne? This scenario is subject of the "Risk Analysis in Civil Protection 2019" report that was recently submitted to the German Bundestag. On the basis of extensive research, experts have listed in detail effects to be expected. What Germans usually only know from abroad results from modeling a strong earthquake near the megacity of Cologne: ground shaking, damaged and destroyed houses, blocked roads, many injured and dead.
A model for the southeastern California lithosphere suggests that a strong upper crust overlies weaker lower rock layers.
The 2018 eruption of Kīlauea Volcano was one of the largest volcanic events in Hawai'i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawai'i at Mānoa and U.S. Geological Survey.
