The 2013 Saravan earthquake occurred with a moment magnitude of 7.7 at 15:14 pm IRDT(UTC+4:30) on 16 April. The shock struck a mountainous area between the cities of Saravan and Khash in Sistan and Baluchestan Province, Iran, close to the border with Pakistan, with a duration of about 25 seconds. The earthquake occurred at an intermediate depth in the Arabian plate lithosphere, near the boundary between the subducting Arabian Plate and the overriding Eurasian Plate at a depth of about 80 km.
It was the strongest earthquake in Iran within the last 40 years, equal in magnitude to the one that shook Tabas in 1978 killing 15,000, and possibly the strongest in the last half-century. The earthquake followed a magnitude 6.3 event near Bushehr.
The town of Mashkel was close to the quake's epicentre, and around 85 percent of the city's buildings were demolished. Thirty-five people were killed in the earthquake.
