The flood mentioned | | |was probably an avalanche of water, sand, | | |volcanic ashes, and lapilli, such as also | | |on other occasions have occurred on the | | |slopes of the same volcano during periods | | |of torrential rains. | | | ----+--------------------+-----+------------------------------------------ No. | Date. |Intensity. | | | Epicenter and effects. ----+--------------------+-----+------------------------------------------ | _Y.
