WebJun 16, 2024 · Hypocenter depths offshore and near islands were set to 10 km and 100 km, respectively. A total of 12 virtual hypocenters were given. Theoretical travel times at each station were calculated for each 12 hypocenters using Hirata and Matsu’ura’s ( 1987) algorithm.

Web2 days ago · Intermittent seismicity in the S cluster and diffusive hypocenter migrations. (a) Temporal change in the seismicity of depth direction. The color represents the magnitude of each event. An earthquake's hypocenter is the position where the strain energy stored in the rock is first released, marking the point where the fault begins to rupture. This occurs directly beneath the epicenter, at a distance known as the hypocentral depth or focal depth. The focal depth can be calculated from measurements … See more In seismology, a hypocenter or hypocentre (from Ancient Greek ὑπόκεντρον (hupόkentron) 'below the center') is the point of origin of an earthquake. A synonym is the focus of an earthquake.
