About 14% of magnitude 6.7 or greater strike-slip earthquakes since 2000 have been supershear. That's 50% more than previously thought. Supershear earthquakes occur when a fault ruptures faster ...

The first studies of the 28 March 2025 magnitude 7.8 Myanmar earthquake suggest that the southern portion of its rupture occurred at supershear velocity, reaching speeds of 5 to 6 kilometers per ...

It is comparable to the roughly 400-kilometer-long 1906 San Francisco rupture, but longer than the 2023 East Anatolian Fault earthquake in Türkiye and the 2002 Denali earthquake in Alaska.

The 200-km (125 miles)-long Stateline fault system is a right-lateral strike-slip fault zone with clear Late Quaternary surface ruptures extending along the California-Nevada state line, from ...

Along a 100 km segment in South Carolina and adjacent states, the Brevard zone contains three separate structural features, all of which dip moderately SE: (1) the narrow Rosman fault, which contain ...
