Sumatran fault

The Sumatran Fault is a major fault line running along the length of the Indonesian island of Sumatra. It is a significant source of earthquakes because it is a strike-slip fault, where two blocks of Earth's crust slide past each other horizontally. This fault accommodates the tectonic pressure caused by the Earth's plates moving in the region, leading to frequent seismic activity. Its movement can cause damaging earthquakes, which have impacted communities and infrastructure on the island. The fault's activity is closely monitored by scientists to better understand and mitigate earthquake risks in Sumatra.
