Researchers from the International Institute for Carbon-Neutral Energy Research developed a new method for detecting small earthquake tremors and successfully applied it to the Nankai Trough, Japan. The technique allowed the accurate estimation of tremor location and propagation speed, leading to the first estimates of this fault's permeability--crucial information in evaluation of earthquake rupture processes.
Until now, researchers have found no evidence of global tectonic activity on planets outside our solar system. Under the leadership of the University of Bern and the National Center of Competence in Research NCCR PlanetS, scientists have now found that the material inside planet LHS 3844b flows from one hemisphere to the other and could be responsible for numerous volcanic eruptions on one side of the planet.
Research conducted by scientists at the University of Rhode Island published today in Nature Communications found that microbes living in ancient sediment below the seafloor are sustained primarily by chemicals created by the natural irradiation of water molecules. Results of this research may have implications for life on Mars.
Scientists have long used information from sediments at the bottom of the ocean to reconstruct the conditions in oceans of the past. But a study in Science Advances raises concerns about the common use of pyrite sulfur isotopes to reconstruct Earth's evolving oxidation state. These signals aren't the global fingerprint of oxygen in the atmosphere, according to new research from Washington University in St. Louis.
The unprecedented cost of the 2018 Kilauea eruption in Hawai'i reflects the intersection of distinct physical and social phenomena: infrequent, highly destructive eruptions, and atypically high population growth, according to a new study led by University of Hawai'i at Mānoa researchers.
A Skoltech researcher has developed a theoretical model of wave formation in straits and channels that accounts for nonlinear effects in the presence of a coastline. This research can improve wave prediction, making maritime travel safer and protecting coastline infrastructure.
In "Perspectives on flood forecast-based early action and opportunities for Earth observations," Claire Nauman et al. focus on flood forecasts and identify opportunities to incorporate Earth observation data into flood forecast-based early action.
Using "Curie" - Google's 10,000-kilometer-long underwater fiber-optic cable connecting Los Angeles, California and Valparaiso, Chile - researchers have demonstrated a novel method for detecting deep-sea seismic activity and waves at the ocean's surface.
Researchers at Stevens Institute of Technology have developed a new machine learning-powered platform, known as OC-SMART, that can process ocean color in satellite images 10 times faster than the world's leading platform. The work, which will be adopted by NASA, is one of the first machine learning-based platforms in ocean color analysis that can process both coastal and open ocean regions globally to reveal data on sea health and the impact of climate change.
There are millions of unplugged oil wells in the United States, which pose a serious threat to the environment. Using drones, researchers from Binghamton University, State University of New York have developed a new method to locate these hard-to-locate and dangerous wells.
