  • unavailable  Gamalama (Indonesia) - Report for 3 October-9 October 2018 - NEW

    PVMBG reported that an explosion from Gamalama at 1152 on 4 October was likely phreatic; it generated an ash plume that rose about 250 m above the summit and drifted NW. Eight volcanic earthquakes were recorded about an hour before the event. Based on satellite data and information from PVMBG, the Darwin VAAC reported that during 5-6 October ash plumes rose to 2.1 km (7,000 ft) a.s.l. and drifted W and NW. The Alert Level remained at 2 (on a scale of 1-4); visitors and residents were warned not to approach the crater within a 1.5-km radius.

  • unavailable  Kilauea (United States) - Report for 3 October-9 October 2018 - NEW

    On 5 October HVO reported that lava at Kilauea had not been active at the surface for 30 days. Seismicity was low, steady, relatively low rates of deformation across the volcano were recorded, and the summit and East Rift Zone (ERZ) produced only minor gas emissions. These data indicated that near-term resumption of activity at the summit or at the lower ERZ was unlikely; the Volcano Alert Level was lowered to Advisory and the Aviation Color Code was lowered to Yellow.

  • unavailable  Kadovar (Papua New Guinea) - Report for 3 October-9 October 2018

    RVO reported quiet conditions at Kadovar during 1-20 September with only diffuse white plumes rising from the volcano. Activity increased on 21 September and remained elevated at least through 26 September, the date the last visual observation was received by RVO. During the period if increased activity dense dark gray and brown ash plumes rose several hundred meters above the summit crater (700-800 m) and drifted NW. Intense incandescence from Main Crater, the SE coastal vent, and other areas was visible. Minor amounts of ash fell on Blup Blup island. On 1 October an ash plume rose to 900 m (9,000 ft) a.s.l. and drifted W. An ash plume was visible in satellite images on 3 October drifting W at an altitude of 2.1 km (3,000 ft) a.s.l.

  • unavailable  Krakatau (Indonesia) - Report for 3 October-9 October 2018

    PVMBG reported that during 1 September-3 October the Strombolian eruption at Anak Krakatau continued, though foggy conditions often prevented visual observations. Ash plumes mainly rose 200-500 m above the crater rim and drifted NW to SW. On 22 September ash plumes rose as high as 2.5 km; ejected incandescent material mostly landed on the flanks (less than 1 km from the crater), and a small amount fell into the sea. Lava flows on the SSE flank also reached the sea. The Alert Level remained at 2 (on a scale of 1-4); residents and visitors were warned not to approach the volcano within 2 km of the crater.
