The 1992 Nicaragua earthquake : a slow tsunami earthquake associated with subducted sediments.
Material type:
TextLanguage: ENG Publication details: 1993Description: 3 p. : illSubject: This earthquake is the first to be detected by modern broadband seismic networks, producing seismograms for inferring rupture mechanisms. The earthquake is interpreted as a slow thrust event occurring on the subduction interface between the Cocos and North American plates. Due to the absence of sediments on the trench floor offshore of Nicaragua, the slip propagated up-dip to the ocean floor. The rupture process was slower than in ordinary subduction zone thrust earthquakes. Tsunami warning systems using long-period waves are indicated to be necessary to reduce the hazard from this type of earthquake
