| Hazard synopsis |
Potential danger could be caused by terminal eruptions producing ash clouds to an altitude of 5 km a.s.l. Moreover, explosive eruptions sending ash clouds up to 10 – 15 km a.s.l. are possible in regional zones of cinder cones in the south and north from the volcano. These eruptions could pose a thread to local and international aviation. |
