Worldwide Volcano News and Updates

CENAPRED reported that during 30 May-5 June gas-and-ash plumes from Popocatépetl rose as high as 2 km above the crater and drifted mostly W and SW, but also NW and ENE. Cloud cover occasionally prevented observations of the plumes and crater. Incandescence from the crater was visible on most nights. Read all

During 30 May-5 June HVO reported that the circulating and spattering lava lake periodically rose and fell in the deep pit within Kilauea's Halema'uma'u Crater, rising as high as the inner ledge about 60 m below the crater floor. Periodic measurements indicated that the gas plume from the vent continued to deposit variable amounts of ash and Pele's hair onto nearby areas. The level of the lava pond in a small pit on the E edge of Pu'u 'O'o crater floor rose back into view. Read all

JMA reported that during 1-4 June seven explosions from Sakura-jima's Showa Crater ejected ballistics 800-1,300 m from the crater. Based on information from JMA, the Tokyo VAAC reported that during 30 May-5 June explosions produced plumes that rose to altitudes of 1.2-3 km (4,000-10,000 ft) a.s.l. and drifted SW, W, and NW.

According to INGEOMINAS, the Observatorio Vulcanológico and Sismológico de Manizales reported that on 4 June observations of Nevado del Ruiz during an overflight and through web cameras located in the vicinity of Arenas Crater revealed that gas-and-ash plumes rose at most 1 km above the crater and drifted W and NW. The next day seismic signals indicated that ash emissions continued. Field observers noted that sulfur dioxide emissions were significant. Read all

RVO reported mild activity from Manam's Southern Crater during the first two weeks of May. Emissions consisted of diffuse white vapor, with diffuse blue plumes observed during 5-6 and 13-14 May. Gray and gray-brown ash clouds rose from the crater on 7, 9, and 12 May. Read all

INGEOMINAS reported that on 17 May ash emissions originating from an area N and W of the cone within Galeras's main crater rose 200 m above the crater rim. During 26-27 May ash plumes rose 800 m above the crater; ashfall was reported in Sandona (13 km NW). Ash emissions occurred on 2 June, and on 5 June plumes rose 1 km and drifted W. Read all

INSIVUMEH reported that on 1 June hot lahars traveled SE down Fuego's Las Lajas and El Jute drainages carrying blocks 2 m in diameter. During 3-5 June explosions produced ash plumes that rose 500-1,000 m above the crater and drifted W and S. Pulses of incandescence from the crater was observed as well as avalanches on the W flank.
