Ragang volcano in central Mindanao is in the center of this August 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 24 km across). Latukan is to the SW, past lava flows with visible levees and pressure ridges that appear to have erupted from flank vents.

Geological summary

The large Ragang stratovolcano, also called Piapayungan, is SE of Lake Lanao in central Mindanao. A crater about 5 km from the summit on the SW flank towards Latukan volcano is surrounded by mostly unvegetated volcanic material, including a lava flow extending 4 km S; this is likely from the 1916 eruption described by Maso (1917). Ragang is one of several dominantly basaltic volcanoes west of the cordillera in central Mindanao. Historical eruptions, many of which were at one time attributed to neighboring Makaturing volcano, have been recorded since 1765.
