An international team of scientists digging in a sea cave in Indonesia has discovered the world's most pristine record of tsunamis, a 5,000-year-old sedimentary snapshot that reveals for the first time how little is known about when earthquakes trigger massive waves.
Engineers from Imperial College London have dispelled a 100-year-old scientific law used to describe how fluid flows through rocks.
Researchers from the University of Hawai'i at Mānoa recently discovered that infrared satellite data could be used to predict when lava flow-forming eruptions will end.
Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that 'slow earthquakes' are occurring continuously, and could encourage damaging earthquakes. Slow earthquakes are quiet, can be as large as magnitude 7, and last days to years. Taking place mainly at the boundary between tectonic plates, they happen so slowly that people don't feel them.
A University of Oklahoma geophysics professor, Xiaowei Chen, details the foreshock activities leading up to the Pawnee earthquake, and highlights the complicated relationship between seismicity and wastewater injection rates in a research study published this week in Scientific Reports. The study details the precursory earthquake (foreshock) sequences that culminated in the September 3, 2016, 5.8 magnitude earthquake near Pawnee, Okla., which ruptured along the previously unmapped Sooner Lake Fault.
University of Alaska Fairbanks researchers have discovered that volcanoes have a unique way of dealing with pressure -- through crystals. According to a new study published in the Journal of Geology, if enough crystals can develop in rising magma, then a network of microscopic crystals can lessen the internal pressure of rising magma and reduce the explosiveness of eruptions.
Accounting for a vegetated and less dusty Sahara reduces the variability of El Niño during the Mid-Holocene to closer to that which is observed in several paleoclimate records. This is shown by researchers at the Department of Meteorology at Stockholm University in a recent study, published in Nature Communications.
Structural geologist Michele Cooke calls it the 'million-dollar question' that underlies all work in her laboratory at the University of Massachusetts Amherst: what goes on deep in the earth as strike-slip faults form in the crust? This is the fault type that occurs when two tectonic plates slide past one another, generating the waves of energy we sometimes feel as earthquakes.
Researchers from Newcastle University (UK), Chengdu University of Technology, Tongji University, China Academy of Space Technology and Wuhan University (China) have been tracking the massive landslide which struck Xinmo Village, Maoxian County, Sichuan Province in China.
Repair petitions filed in the wake of the 1918 Puerto Rico earthquake and tsunami, stored and forgotten in the San Juan archives for nearly 100 years, are giving scientists a house-by-house look at the damage wrought by the magnitude 7.3 event.
