An ash plume rises to 12.5 km above the summit of Mayon volcano on 13 September 1984, seen here from Santa Misericordia on the E flank. This marked the peak of the first phase of the 1984 eruption, which began on 9 September. The first phase lasted until 18 September and included the eruption of pyroclastic flows, which traveled down the NNW slope, and lava flows down the SW flank. Photo by N.B.
