Roland Burgmann, University of California Berkeley Decadal changes in aseismic fault slip rate on partially coupled faults reflect long-term changes in fault loading and/or fault-frictional properties that can be related to earthquake cycle processes. We consider constraints on aseismic fault slip rates from historical alignment array measurements,…

Summary Professor Kenji Satake, a renowned seismologist and tsunami researcher, discusses his research on historical earthquakes and tsunamis using interdisciplinary approaches. He emphasizes the importance of combining geophysical, geological, and historical data to understand the timing and magnitude of these natural disasters. His work has uncov…

Summary This special episode is to highlight the Japan Geoscience Union (JPGU) as a seismic force in geoscience, which offers a forum for the exchange of earth-shattering ideas and groundbreaking discoveries. Their annual meeting in Chiba, Japan this year brought together researchers from various geoscience disciplines and explored a wide range of …

Savvas Marcou, University of California Berkeley MyShake is a free smartphone application, developed at UC Berkeley, that serves as one of the main delivery mechanisms for earthquake early warning (EEW) alerts issued to the US West Coast by the USGS ShakeAlert system. While it is most well-known for delivering alerts to the public, MyShake was orig…

Zhigang Peng, Georgia Institute of Technology Earthquakes are not frequent in the Southeastern United States (SEUS), but they do occur in areas with long-term seismic activity and in new regions with no clear seismic history. Most of these earthquakes have relatively small magnitudes (less than 1) and are therefore not well recorded by the current …

Ettore Biondi, California Institute of Technology Traveltime-based tomographic methods have been extensively explored and employed by researchers since the 80s. Such algorithms have been successfully applied to various geophysical applications, ranging from seismic exploration to global to regional seismological scales. However, given the advanceme…

In this episode, we are speaking to Dr. Joe Aslin, Deputy Editor Communications Earth & Environment, an open access journal from the Nature Portfolio publishing high-quality research, reviews and commentary in all areas of the earth, environmental and planetary sciences. We are talking about a fascinating paper published in this journal discussing …

Janet Watt, U.S. Geological Survey Investigating the geologic record of shallow megathrust behavior is imperative for estimating the earthquake hazard and tsunamigenic potential along the Cascadia subduction zone. Ship-borne sparker seismic imaging and multibeam mapping is integrated with targeted autonomous underwater vehicle (AUV) bathymetry and …

Tree rings serve as a natural archive for studying past climate conditions. By analyzing the tree rings, researchers can date the year the tree was growing and reconstruct past droughts, floods, and wildfires. Nitrogen is a critical element for forest ecosystems and its availability affects forest health and productivity. Climate extremes like drou…

Jeanne Hardebeck, U.S. Geological Survey Aftershock triggering is commonly attributed to static Coulomb stress changes from the mainshock. A Coulomb stress increase encourages aftershocks in some areas, while in other areas termed “stress shadows” a decrease in Coulomb stress suppresses earthquake occurrence. While the predicted earthqu…

Theresa Sawi, U.S. Geological Survey Repeating earthquakes sequences are widespread along California’s San Andreas fault (SAF) system and are vital for studying earthquake source processes, fault properties, and improving seismic hazard models. In this talk, I’ll be discussing an unsupervised machine learning‐based method for detecting …

Welcome to "My Sediments Exactly," Springer’s latest geo and earth science podcast where we take nothing for Granite. We’ll be digging and diving, making sure to bring you the best science and scientists to keep you updated on everything geo and earth sciences. ! You'll crack up at the joints and marvel at the faults because, in this show, it's all…

Andres Pena Castro, University of New Mexico The seismicity detected in the Antarctic continent is low compared with other continental intraplate regions of similar size. The low seismicity may be explained by (i) insufficient strain rates to generate earthquakes, (ii) scarcity of seismic instrumentation for detecting relatively small earthquakes, …

Zachary Smith, University of California Berkley Intense dynamic stresses during earthquakes can activate numerous subsidiary faults and generate off-fault damage that alters fault properties and can impact the source processes and rupture dynamics of future earthquakes. Distinguishing how much damage accumulates during a single earthquake versus mu…

Yifang Cheng, Tongji University, Shanghai Earthquake focal mechanisms offer insights into the architecture, kinematics, and stress at depth within fault zones, providing observations that complement surface geodetic measurements and seismicity statistics. We have improved the traditional focal mechanism calculation method, HASH, through the incorpo…
