The JMA has raised the Kirishima at "Warning - a.k.a. near Crater warning" (Volcanic Warning System for volcanoes where volcanic alert levels are not applied)), following a larger number of earthquakes;
Between 2h and 17h local on February 28, 2016, 53 volcanic earthquakes, with a shallow epicenter, were recorded around the crater Iozan. Denying access to the fumariolan site was enacted by local authorities on February 19, due to high levels of H2S, and possible big cinders drops in a radius of 1 km. in case of eruption.
