The Sunda Trench is an oceanic trench located the Indian Ocean off the island of Sumatra. Numerous aircraft and vessels have gone missing in the region of the trench over the year, giving it a somewhat mysterious reputation akin to the Bermuda Triangle's.
The Sunda Trench is certainly situated in one of the most geologically violent spots in the world: it is near the collision point for several tectonic plates, there are large numbers of active volcanoes in the area and earthquakes are frequent. Some of the devastating natural disasters that have occurred in the Sunda Trench region include:
-The 1815 volcanic eruption of Tombora on Sumbawa Island, thought to be the most massive in recorded history.
-The 1883 volcanic eruption on Krakatoa Island, an explosion so violent it was heard 5'000 km away.
