چکیده

The 2021 August 14 MW 7.2 Nippes, Haiti earthquake occurred 75 km west of the epicenter 2010 Leogane (Haiti) on transpressive Caribbean - North America plate boundary. We present an updated fault map for Hispaniola and model coseismic early postseismic slip using Interferometric Synthetic Aperture Radar pixel offsets. find ruptured multiple segments Enriquillo-Plantain Garden Fault Zone. Slip in two main sub-events either side a restraining bend at Pic Macaya, with ?2.7 m peak reverse-slip east bend. To west, jumps further ruptures ?1.2 left-lateral slip. Afterslip 4 days following event shallow depth adjacent to rupture areas reached surface Macaya.

Complex rupture during the 12 January 2010 Haiti earthquake

Initially, the devastating Mw 7.0, 12 January 2010 Haiti earthquake seemed to involve straightforward accommodation of oblique relative motion between the Caribbean and North American plates along the Enriquillo–Plantain Garden fault zone. Here, we combine seismological observations, geologic field data and space geodetic measurements to show that, instead, the rupture process involved slip on ...

Complex earthquake rupture and local tsunamis

[1] In contrast to far-field tsunami amplitudes that are fairly well predicted by the seismic moment of subduction zone earthquakes, there exists significant variation in the scaling of local tsunami amplitude with respect to seismic moment. From a global catalog of tsunami runup observations this variability is greatest for the most frequently occurring tsunamigenic subduction zone earthquakes...

Limitations of rupture forecasting exposed by instantaneously triggered earthquake doublet

Earthquake hazard assessments and rupture forecasts are based on the potential length of seismic rupture and whether or not slip is arrested at fault segment boundaries. Such forecasts do not generally consider that one earthquake can trigger a second large event, near-instantaneously, at distances greater than a few kilometres. Here we present a geodetic and seismological analysis of a magnitu...
