The University of California, Davis was awarded a three-year, $386,347 Project Grant from the National Science Foundation Division of Earth Sciences to test the thermal shear instability hypothesis for deep slab seismicity. This funding supports basic research under the NSF's Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through atmospheric, earth, and ocean sciences. Specifically, the university will conduct research from July 2021...
The National Science Foundation's (NSF) Division of Earth Sciences awarded a $275,605 Project Grant to Florida International University (FIU) to study the long-term history of earthquakes along the Dead Sea Fault (DSF) in Israel. The project, titled "EARTHQUAKE TEMPORAL OCCURRENCE VARIABILITY (CLUSTERING) OBSERVED IN THE LONGEST DETAILED PALEOSEISMIC RECORD: CLIMATIC MODULATION ON THE TECTONIC SIGNAL -THE DEAD SEA FAULT (DSF) IN ISRAEL PROVIDES A UNIQUE OPPORTUNITY TO STUDY THE LONG-TERM HISTORY OF EARTHQUAKES ALONG A MAJOR FAULT", aims to investigate the relationship between climate variations and the timing of earthquakes, using a range of methods such as time series analysis, GIS tools, geological mapping, and computer models. The 3-year project, running from September 1, 2024 to August 31, 2027, is a collaborative effort between FIU and Israeli researchers, with the U.S. team focusing on modeling fault mechanics and mathematical analysis, while the Israeli team conducts geological mapping and seismite modeling. The findings may help improve understanding of how climate change might affect earthquake timing on other major fault systems.
