Branch faults in continental transform earthquakes

Researchers Ross Stein and Peter Bird have proposed a hypothesis that many major continental transform earthquakes begin on branch faults, which they describe as “on-ramps” that lead to ruptures on larger, more mature faults. This theory, if validated, could have significant implications for earthquake monitoring and preparedness, potentially altering how and where seismic networks are …

Seismic signal traced to Greenland rockslide

In September 2023, a globally detected seismic signal sparked curiosity among scientists when it persisted for up to nine days. This signal, unlike typical earthquake waves, was traced back to a massive rockslide in Greenland’s Dickson Fjord. A multinational team of researchers, including those from the Karlsruhe Institute of Technology (KIT), set out to uncover …

Precursory seismicity in earthquake prediction

A groundbreaking study by Társilo Girona, a research assistant professor at the University of Alaska Fairbanks (UAF) Geophysical Institute, suggests that advance notice of major earthquakes could be possible by detecting precursory seismicity—low-level tectonic activity occurring days to months before significant quakes. This study, published in Nature Communications and co-authored by geologist Kyriaki Drymoni of …

AI earthquake prediction breakthrough

Researchers at The University of Texas at Austin have made significant strides in the field of AI earthquake prediction, potentially revolutionizing how we approach the mitigation of earthquake-related risks. The team developed an AI algorithm capable of predicting 70% of earthquakes a week before they occurred during a seven-month trial conducted in China. This trial …

Advances in Cascadia earthquake prediction

Recent seismic activity off the coast of British Columbia has renewed concerns about the potential for a significant megathrust earthquake, often referred to as “The Big One,” which could occur along the Cascadia subduction zone. This tectonic boundary spans approximately 1,000 kilometers from Northern California to Vancouver Island, where the Juan de Fuca plate subducts …

Linking climate change and earthquakes

Recent research and expert opinions are drawing connections between climate change and seismic activities, suggesting that climate change and earthquakes might have a more intertwined relationship than previously understood. This complex link revolves primarily around the impacts of global warming on glaciers and sea levels, which in turn may affect tectonic stability.

Understanding intraplate earthquakes

Intraplate earthquakes are seismic events that occur within the stable interiors of tectonic plates, far from the active boundaries where most earthquakes originate. Prof Éric Calais and Jean François Ritz highlight the unpredictable nature of these quakes, which can strike unexpectedly in geologically quiet regions.
