Mt. Popa volcano is a large stratovolcano at the northern end of the Pegu Yoma Hills range in central Burma. The steep-sided volcano rises 1150 m from its base of a surrounding lava plateau. It had an eruption in or around 442 BC, which is preserved in local legends.

The main edifice of Mt Popa consists of overlapping basaltic and basaltic-andesite lava flows, tephra layers and scoria deposits from strombolian eruptions, which seem to have prevailed during the later stages of its formation.

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.
