Magma genesis of Popa volcano

Popa Volcano

Geologic and tectonic settings of Myanmmar are the same with Japan; this country lies at convergent margin, and therefore, a lot of earthquakes and some volcanoes are present. Several geological research of Myanmar have been conducted last decade and new discoveries have reported. For example, it was reported that three Quaternary volcanoes are present in the Central Lowlands; Popa, Monywa, and Singu (Figure 1). Popa volcano, the largest of these volcanoes, should be an active volcano because last eruption was reported to be less than 10,000 years before present (Figure 2).
