Nettet18. okt. 2024 · Typically, aftershocks are defined within an area around the mainshock’s source region (i.e., the ruptured fault segment, which is about 50–100 km long for a magnitude 7.0 earthquake). Most aftershocks occur on the main rupture surface; hence, they are often used to define the complex geometry of the rupture plane.
