WebHá 10 horas · An earthquake of magnitude 7 struck Java, Indonesia on Friday, the European-Mediterranean Seismological Centre (EMSC) said. The quake was at a depth of 368 miles, EMSC said. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. The sides of a fault move past each other smoothly and aseismically only if there are no irregularities or asperities along the fault surface that increases the frictional resistance. Most fault surfaces do have such asperities, which leads to a form of stick-slip behavior. Once the fault has locked, continued relative motion between the plat…
