Mount Colo (Gunung Colo), is only 500m above sea level, but in 1983 it wiped out the whole island. The islands 7000 residents were evacuated by the indonesian navy, with zero deaths from the eruption. 700,000 coconut trees were not so lucky  with devastating pyroclastic flows and lava covering 90% of the island, wiping out all eight villages. The island remained virtually uninhabited for decades. People only slowly began returning in the late 1990s to rebuild. These days the volcano is a popular trek and we were able to walk right inside the active crater.

But it’s a bit of a deal to get there with a 45 minute daredevil motorbike ride  through jungle,  along the beach and up the lava flow. Then it’s a 45 minute walk, constantly jumping over a very hot stream to get to the crater.
