The magnitude was fixed to M = 7.5. The hazards are related to two basic phenomena resulting from the failure of a geological fault. The deterministic analysis considers one source, one magnitude and one distance at a time. California, Japan). DSHA - Deterministic Seismic Hazard Analysis. Deterministic Seismic Hazard Analysis (DSHA) The DSHA was performed by assuming the Motagua fault as a linear seismic source of 230 km. The most perspective will be gained if both deterministic and probabilistic analyses are conducted. Factors that inﬂuence the choice include the decision to be made (i.e. the purpose of the hazard or risk assessment), the seismic environment (whether the location is in a high, moderate, or low seismic risk region), and the scope of the Seismic Hazard Analysis. Deterministic Seismic Hazard Analysis - How is Deterministic Seismic Hazard Analysis abbreviated? The first basic step in seismic hazard analysis is to collect the input data on tectonics and seismicity and on ground motion scaling models.
