a weak eruption of ash on 25 May


NYIRAGONGO Democratic Republic of the Congo 1.52°S, 29.25°E; summit elev. 3,469 m

a weak eruption of Nyiragongo on 21 May, by the evening of 25 May the volcano no longer visible on satellite imagery due to meteorological clouds


SANTA MARÍA Guatemala 14.756°N 91.552°W; summit elev. 3,772 m

during 18-21 May weak-to-moderate explosions producing gas-and-ash plumes to 4.8 km, many with avalanches of incandescent volcanic material


SEMERU Java, Indonesia 8.11°S, 112.92°E; summit elev. 3,676 m

a thin ash plume visible on satellite imagery on 22 May around 1625, the plume to a height of ~4.3 km


SIRUNG Lesser Sunda Islands, Indonesia 8.51°S, 124.15°E; summit elev. 862 m

news reports of an eruption around 13 May were false


SOUFRIÈRE HILLS Montserrat, West Indies 16.72°N, 62.18°W; summit elev. 1,052 m

volcanic activity during 14-21 May at low levels, on 21 May intense rainfall producing large mudflows and the entire width of a valley floor flooded, the sulfur-dioxide flux low most of the report period
