Parker volcano, seen here from the E, is located at the S end of Mindanao Island in the Philippines and was unknown to most volcanologists until recent years. Reconnaissance studies of the volcano revealed resemblances to Pinatubo volcano, which also produced thick deposits of pyroclastic flows around its flanks. Parker is now thought to be the source of a major eruption in 1641 that plunged much of Mindanao into darkness.
