Research & Commentary: Thanks to Mitigation Measures, Induced Seismicity Risks Dropping Quickly

The U.S. Geological Survey (USGS) released a report projecting potential induced seismicity (man-caused earthquakes) across the United States in 2017 and found the number of people living in an area of “significant” risk (1–12 percent chance ...

Trio of tremors shake South Texas, expert says area earthquakes are on the rise

A cluster of small earthquakes shook the Coastal Bend on Wednesday, with most activity centered northwest of Corpus Christi, according to a United States Geological Survey seismologist. Since the

Deep earthquakes triggered by the olivine-poirierite transition

Seismicity decreases with depth because elevated confining pressure prevents frictional sliding of faults. However, seismicity tends to increase with depth in the mantle transition zone (depths of 410−600km).

State of the Art and Practice in Earthquake Induced Soil Liquefaction Assessment

Earthquake-induced soil liquefaction, often described as the phenomena of seismic generation of excess porewater pressures and consequent softening of granular soils, is a leading cause of earthquake damage worldwide. Accurate assessments of where ...

Why earthquakes sometimes still occur in tectonically silent regions

Global distribution of natural and induced seismicity. Natural earthquakes with moment magnitude higher than 5 are color-coded according to their hypocenter depth (upper right colorbar, U.S. Geological Survey (USGS) catalog, year 2021). Induced earthquakes ...

Human-caused quakes are real and here’s why stable regions snap

Earthquakes are often treated as acts of nature that strike without warning along famous plate boundaries, yet a growing body of evidence shows that human activity can also trigger damaging shaking. In regions long considered geologically quiet, industrial ...

Earthquakes in unlikely places: What's triggering them?

In 2023, Texas and California were nearly tied for the number of magnitude 3 and larger earthquakes, which is honestly kind of wild when you think about it. Texas isn't supposed to be earthquake country. Yet the average number of earthquakes per year with ...
