After another series of very strong explosions on 1 March, Mayon volcano apparently calmed somewhat, although a sizeable lava flow continued to pour through the Bonga valley on its southeastern flank. One of the explosions on 1 March was described as even more powerful than those on the preceding day, because it ejected huge incandescent blocks or bombs, reported to be as big as houses. Large pyroclastic flows descended on all sides of the mountain. Again, towns on the southwestern flank were showered with ash. Most stricken was the town of Guinobatan, where residents had to find their way in darkness. The number or people displaced since the beginning of the eruption on 24 February is about 63,000.
