Slow slip earthquake

WebbNonvolcanic tremor is observed in close association with geodetically observed slow-slip events in subduction zones. Accumulating evidence points to these events as members of a family of slow earthquakes that occur as shear slip on the downdip extensions of fault zones in a regime that is transitional between a frictionally locked region above and a … Webb25 maj 2024 · Slow slip earthquakes, a type of slow motion tremor, have been detected at many of the world's earthquake hotspots, including those found around the Pacific Ring of Fire, but it is...

Webb1 aug. 2024 · We refer to distinct episodes of accelerated slip as slow slip events (SSEs), creep events and slow (or silent) earthquakes. Slip duration at a point on a fault during an earthquake is generally less than ∼10 s, while an SSE may endure from tens of seconds to tens of years.
