Roundup of Global Volcanic Activity – New Activity for the week of 8 February-14 February 2017
Cleveland | Chuginadak Island (USA) : AVO reported that weakly elevated surface temperatures in Cleveland’s summit crater were identified in satellite images during 7-9 February. Minor steaming was noted on 8 February. AVO noted that these observations were consistent with the presence of a lava dome that began extruding in the summit crater in late January. The Aviation Colour Code remained at Orange and the Volcano Alert Level remained at Watch.
Pacaya | Guatemala : On 9 February INSIVUMEH reported that moderate explosions at Pacaya’s Mackenney cone had been detected during the previous few days. Incandescent material was ejected 30-50 m high and filled a large part of the crater; lava spilled over the crater rim and traveled 300 m down the NW flank. Incandescent material was ejected as high as 30 m during 11-12 February. Small Strombolian explosions were visible on 13 February. The lava flow continued to advance the next day.
Piton de la Fournaise | Reunion Island (France) : OVPF reported that during 8-14 February volcanic tremor at Piton de la Fournaise was high, with levels reaching those observed at the onset of the eruption on 31 January. The eruptive vent was perched on top of a cone that was 30-35 m high and 190 m wide (at the base). The lava level inside of the cone was low, or about half of cone’s height, and incandescent material was ejected from the vent. Lava was mainly transported through a lava tube, though a few branches at end of tube were active.
Takawangha | Andreanof Islands (USA) : On 10 February AVO stated that the seismic swarm that began at Takawangha on 23 January had significantly declined the previous week and that seismicity was nearly at background levels. The Aviation Colour Code was lowered to Green and the Volcano Alert Level was lowered to Normal.
