PLOMO
Event description
On 14 November 1984,
Rio del Plomo was dammed and a lake began to form
some days later. On 9 January 1985, the lake had reached 2.8 km in length and
1.1 km in width. Catastrophic floods did not occur, probably due to the fact
that water was able to flow out over the heavily broken ice at the contact
between the advancing glacier front and the opposite rocks of the valley wall.

Data source
Espizua,
L. E., Bengochea, J. D. (1990): Surge of Grande
Remarks
The return of the surge appeared to be about 50 years.
The glacier flood triggered by the last event in 1934 had caused heavy damage -
especially to the Trans-Andean railway - loss of lives.
