Heavy rains at the top of Santiaguito volcano generated strong lahars in the bed of the Nima I River.
The bed of the river got suddenly filled up with plenty of pasty fine material containing with blocks of 50 to 70 cms, trunks and tree branches, and a hot mudslide with a width of 30 meters.
Lahars are part of the activity of the Santiaguito volcano due to the amount of rain in the volcanic area.
