1257 Samalas eruption

The 1257 Samalas eruption was a major volcanic eruption of the Samalas volcano, next to Mount Rinjani on the island of Lombok, Indonesia. It left a large caldera next to Rinjani volcano. This volcanic eruption reached a volcanic explosivity index of 7, making it one of the largest eruptions of the Holocene. The existence of this eruption was originally inferred from ice core information revealing a spike in sulfate deposition around the year 1257; in 2013 the source of this eruption at Samalas was definitively proven thanks to historical records from that time.
