Turrialba Volcano is at it again.

The Volcanological and Seismological Observatory (OVSICORI) released video Tuesday of an eruption at 2:07 a.m., when a column of hot rocks and ash rocketed out of the colossus. The eruption sent ash 2 kilometers into the air.

The eruption's most dramatic moment comes 14 seconds into the video when a rush of heat from the crater flashes white on the screen.

Ash and sulphur smells from the eruption were reported as far away as Cuidad Quesada and across Alajuela, Escazú, Heredia and Curridabat, among other places. See the map from OVSICORI for more details:

OVSICORI said on its Facebook page that it was investigating the eruption to see if it was related to the volcano's recent activity.
