The volcano s tremendous explosion is still going on.
According to the nearby observatory OVSICORI-UNA, a powerful phreatic explosion erupted from the summit crater at about 05:42 local time this morning. The volcano ejected a taller and denser column of gas and steam, with some ash thrown in for good measure.
The plume rose to a height of 12,900 feet (3,900 meters) and drifted north-northwest. The conflagration lasted around three minutes.
Lahars (mud flows) were produced by the eruption and proceeded in a northerly direction via the drainage system.
