A global probabilistic tsunami hazard assessment from earthquake sources

March 19, 2019 tsumapsneam

Large tsunamis occur infrequently but have the capacity to cause enormous numbers of casualties, damage to the built environment and critical

The stronger shallower segment strains and stresses the deeper segment of the seismogenic zone. The deeper segment is weaker and fails at lower stress build-up in 2016-class earthquakes. Higher shear strength along the shallow segment allows longer periods (>110 yr) of stress build-up, the release of which may result in great 1960-class earthquakes that can also extend into the deeper segment. Interseismic GPS velocities indicate high crustal shortening above the deeper section of the seismogenic zone (right inset). Pore fluid pressure gradients along the plate interface are related to the geological configuration of the margin, and exert a mechanical control on the strength segmentation and timing of stress release in the seismogenic zone (left inset).
