Popa
"Mount Popa, in central Burma (Myanmar), is a large, steep-sided composite cone that rises 1150 m above a surrounding lava plateau to a height of 1518 m. The main edifice consists of overlapping basaltic and basaltic-andesite lava flows, pyroclastic deposits, and scoriaceous material originating from strombolian eruptions that may have dominated later stages of the volcano's growth. Mount Popa contains a 1.6-km-wide, 850-m-deep horseshoe-shaped caldera that is widely breached to the NW and formed as a result of slope failure. A 3 cu km debris-avalanche deposit covers an area of 27 sq km north of the breach. Local legends describe an eruption in 442 BC (Stephenson and Marshall, 1984)."  -Smithsonian Volcano Archive
