Mapping the invisible: how sub-daily GPS sheds light on early postseismic deformation

Chinese Academy of Sciences — Mon, 05 Aug 2024 08:05:55 EST

A pioneering study has unlocked new insights into the immediate behavior of the Earth's crust following earthquakes. By applying sub-daily Global Positioning System (GPS) solutions, researchers have precisely measured the spatial and temporal evolution of early afterslip following the 2010 Mw 8.8 Maule earthquake. This innovative approach represents a significant advancement in seismic analysis, providing a more accurate and rapid depiction of ground deformations that are crucial for assessing seismic hazards and understanding fault line activities.

'Hybrid' disaster response shows how localization saves lives

University of Notre Dame — Thu, 13 Jun 2024 17:05:15 EST

In August 2021, an earthquake struck southwest Haiti, killing thousands of people and leaving more than half a million seeking help. Assessment of this disaster and its response can serve as a model for evaluating future disasters and making life-saving improvements, according to new research from the University of Notre Dame.

Better Understanding of Earthquake Risks

Karlsruhe Institute of Technology (KIT) — Thu, 18 Apr 2024 03:05:34 EST

When one tectonic plate slides underneath another tectonic plate, strong earthquakes result rather frequently. The severe earthquake off the coast of Taiwan in early April 2024 also took place at such a subduction interface.

The year of dragon: revisiting the Dragon King

Chinese Academy of Sciences — Thu, 29 Feb 2024 09:30:10 EST

The January 1, 2024, Noto Peninsula, Japan, Mw7.5 earthquake has undoubtedly been one of the most important earthquakes in 2024, causing widespread attention of the seismological community worldwide. In a recent Editorial of Earthquake Research Advances, titled "Tracing the pace of an approaching 'seismic dragon king': additional evidence for the Noto earthquake swarm and the 2024 Mw7.5 Noto earthquake", Liu, Yue, and her coauthors comment on the predictability of this earthquake.

CyberShake study uses Summit supercomputer to investigate earthquake hazards

Oak Ridge National Laboratory — Mon, 12 Feb 2024 13:05:21 EST

Researchers at the Statewide California Earthquake Center, or SCEC, are unraveling the mysteries of earthquakes by using physics-based computational models running on high-performance computing systems at the Department of Energy's Oak Ridge National Laboratory. The team's findings will provide a better understanding of seismic hazards in the Golden State.
