Epicenter The point on the Earth's surface directly above the focus or hypocenter of an earthquake (the point within the Earth where the earthquake originated). Inverse-gamma distribution A two-parameter family of continuous probability distributions on the positive real line, which is the distributi...
Earthquake FocusThe focus of an earthquake is where pressure builds along a fault line which fails deep underneath the crust of the Earth. The point directly above the focus is termed the epicenter. Image: Fault plane diagramFor You and Your Loved Ones With preparedness and safety measures, ...
Immediately after a destructive earthquake, the real-time seismological community has a major focus on rapidly estimating the felt area and the extent of ground shaking. This estimate provides critical guidance for government emergency response teams to conduct orderly rescue and recovery operations in ...
definite relationship between the two depends on a lot of factors, such as the depth of the hypocenter or focus, the composition of the ground surrounding the hypocenter, the type of terrain between the epicenter and measuring device, and the device location or its distance from ...
epicenter of the earthquake, such as Noto town2(Fig.1b). Additionally, approximately 3 min after the earthquake occurred, a tsunami of 80 cm was observed at a tide gauge station located at the mouth of the Jintsu River in Toyama Bay3, more than 80 km from the epicenter. Initially, we...

Slab buckling and folding in the MTZ have been observed in several regions, which provide an important control on the distributions and focal mechanisms of deep-focus earthquakes e.g. ref. 35. The physical processes that permit the occurrence of deep earthquakes are still not well understood36....
(2013), this chapter focuses on discovering women's leadership activities in the post-disaster reconstruction and recovery. Gleaned from local women's focus groups, in-depth interviews with various stakeholders affected by the earthquakes, and observations made by local adult women on site at the ...
