Chaiten Volcano, Chile - John Seachch

Seismicity associated with the eruption of Chaitén volcano in Chile has decreased over the past week. Viscous lava is still being erupted into the dome, but this is occurring at a reduced rate. Dome collapse is still a danger, with pyroclastic flows potentially traveling down flanks of the volcano and valleys. On 19th of January there was a collapse of spines of the dome, with block and ash moving down the eastern and southeastern flank. During an overflight on 21st January the prominent spines were no longer present on the lava dome. Several steep landslides were visible on the eastern side of the dome. Thermal imaging shows many hotspots on the dome. The volcano is still at alert level RED due to the ongoing eruptions.

Rabaul Volcano, Papua New Guinea - John Seach

Ash emissions from Rabaul volcano in Papua New Guinea closed Tokua airport between Monday and Friday this week. Hundreds of people have not been able to leave, or fly into East New Britain province. A north-west wind is pushing plumes towards Tokua airport 20 kilometres away. Some incandescent lava fragments were emitted from Tarvurvur cone. Most of the lava fragments fell back into the crater but some fell on the slopes of the volcano. A local shipping company has offered to take up to 400 passengers to an airport in nearby New Ireland Province, which is not affected by the volcano. Moderate level seismicity accompanied the eruptions. An earthquake occurred at about 07:47 a.m. yesterday (magnitude 5.6), and was located about 135 km southeast from Rabaul at a depth of about 40 km. The earthquake was tectonic in origin. People are advised to stay more than 2 km away from Turvurvur cone due to ongoing explosive activity.

Chaiten Volcano, Chile - John Seach

Seismicity at Chaiten volcano has remained stable over the past few weeks, with 2-6 events per hour. On 25th and 28th December, ash emissions reached 2 km above the crater. A lava dome continues to grow in the crater, producing instability on the summit and flanks. Explosions from the lava dome are possible and create the risk of pyroclastic flows. The volcano remains at the highest alert level - RED.
