Following renewed unrest and a minor eruption beginning last August, earlier today a more significant explosion occurred, sending ash to 20,000ft (6km) and generating a moderate pyroclastic flow which travelled 1.5km (~1 mile) down the southwest flank, though fortunately did not affect adjacent communities. No injuries have been reported and this event was smaller than the powerful explosion in 2015. JMA has kept the alert level at 3 (on a scale of 1-5).

This follows the unrest in August, when the Alert Level was raised to 4, as there were concerns about a repeat of the large explosion in 2015. This subsequently declined, the Alert Level dropped to 3, where it remains. [more]
