JMA raised the Alert Level for Yakedake to 2 (on a scale of 1-5) on 24 May, noting that the number of small volcanic earthquakes with epicenters near the summit began increasing around 2300 the day before. The report also noted that minor inflation near the summit was continuing. Daily small volcanic earthquakes continued to be counted through 31 May.

Hydrothermal explosion kills four people

A hydrothermal explosion around 1430 on 11 February killed four people at a highway construction site, located in a geothermal area along the narrow Azusa-gawa River ~2 km SE of the summit. The Geological Survey of Japan reported that there were at least two explosions from the vent (12 m long and 6 m wide). The first, a large explosion, created a 1,500-m-high plume composed of mud and gas, and caused collapse of the river bank, burying the primary vent. A second explosion scattered mud and gas within 200 m of the vent. JMA staff who surveyed the site on 12 February and 13 March noted that fume rising to a height of 20 m was almost at the boiling point. No explosions have been reported since 12 February.
