Features of a shallow focus earthquake
WebIn earthquake: Shallow, intermediate, and deep foci The deeper-focus earthquakes commonly occur in patterns called Benioff zones that dip into the Earth, indicating the presence of a subducting slab. Dip angles of these slabs average about 45°, with some shallower and others nearly vertical. WebApr 16, 2024 · Shallow-focus earthquakes are generally less than 40 miles deep with strong shaking near the epicenter – the point in the earth where the rupture occurs. Deep-focus earthquakes are greater than 40 miles deep with shaking felt over a wider area. ... Magnitude and depth are two basic features of an earthquake that are important for ...

WebIn seismology, the depth of focusor focal depthis the depth at which an earthquakeoccurs. Earthquakes occurring at a depth of less than 70 km (43 mi) are classified as shallow-focus earthquakes, while those with a focal depth between 70 km (43 mi) and 300 km (190 mi) are commonly termed mid-focus or intermediate-depth earthquakes.[1]
