The eruption was preceded by mild activity that picked up about 10pm local time last night.
Tremors were also felt at the volcano, indicating magma was rising to the surface.
Lava fountains were then seen shooting up from the crater from about midnight local time, increasing in activity.
By about 12.30am, the eruptive episode reached its peak phase with lava jest 1km high.
A column of ash and steam surpassed the lava, however, reaching up to 10km in height.
