There may be delayed release in the immediatley following forecast or the energy may have released volcanically. Global volcanoes were very active through the period. Etna erupted on 15 May and Piton de la Fournaise on 17 May. Lava was still flowing today and may yet reach the ocean. Other volcanoes were either hot or in minor eruption. Kilauea inflation and lava lake levels grew slightly and then stabilised. Great volcano forecasting success.
