| contents | Structure of the Managua graben, Nicaragua, from remote sensing images A. Frischbutter Ciencias de la Tierra Nicaragua seismology neotectonic Remote sensing Managua graben From remote sensing interpretations, combined with seismological data of the 1972 earthquake, the Managua Fault Zone isseen as a N-S - trending, composite structure of regional importance. The eastern margin of the Managua Fault Zone is formed bylower-order, N-S - trending graben structures such as the Managua graben or the Airport graben, which are bordered by obliquefaults. The intensity of lateral movements on these N-S trending faults seems to decrease to the east as normal faulting increases.Lateral components on N-S trending faults are mainly dextral in recent times. In combination with the NW - trending marginalfaults of the Nicaragua depression this represents a transpressional regime for the Managua Fault Zone. Components of left lateralmovements on NNE- to NE - trending structures are clearly indicated from seismological data for the 1972 Managua earthquake(extension within substructures like the Managua graben, Airport graben). N-, NW- and NE - trending planes should be regardedas recently active in the region. These kinematic relations must be taken into account for seismic hazard assessment: NE - trendingplanes are emphasized because of their extensional regime.It is postulated that during the 1972 event only the western part of the Managua graben was activated. Higher recent stressconcentration along the eastern margin of the graben may be a consequence, among others. 2002 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56841202 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.41 |
