Level 5 (Evacuate) and Level 4 (Evacuation of elderly people etc.) concern residential areas; Level 3 (Do not approach the volcano) and Level 2 (Do not approach the crater) restrict access to the mountain or crater area; Level 1 means ‘Note that this is an active volcano’. Volcanoes without alert levels receive warnings such as ‘danger near the crater’ instead.
