(11) Volcanic Activity Summary: | Very strong explosive eruption of Karpinsky volcano began at 21:45 UTC on April 21, 2016. According to satellite data, ash is reaching 40,000 ft (12 km) a.s.l. and two ash plumes are drifting to the southeast – east – northeast of the volcano on the height 40,000 ft (12 km) a.s.l. and to the northeast of the volcano on the height 20,000 ft (6 km) a.s.l. at this time. Ash emission is continuing. Ongoing activity could affect international and low-flying aircraft. |
(12) Volcanic cloud height: | First ash plume 39360 ft (12000 m) AMSL Time and method of ash plume/cloud height determination: 20160421/2145Z – NOAA 18 (4m5) Second ash plume 19680 ft (6000 m) a.s.l. Time and method of ash plume/cloud height determination: 20160421/2145Z – NOAA 18 (4m5) |
(13) Other volcanic cloud information: | First ash plume Distance of ash plume/cloud of the volcano: 17 mi (27 km) Direction of drift of ash plume/cloud of the volcano: ESE / azimuth 120 deg Time and method of ash plume/cloud determination: 20160421/2145Z – NOAA 18 (4m5) Second ash plume Distance of ash plume/cloud of the volcano: 62 mi (100 km) Direction of drift of ash plume/cloud of the volcano: NNE / azimuth 30 deg Time and method of ash plume/cloud determination: 20160421/2145Z – NOAA 18 (4m5) |
(14) Remarks: | This strong explosive eruption is extremely hazardous for aircraft downwind. There was one known a moderate explosive eruption of Karpinsky volcano which occurred on 05 November 1952, and it was entails with a strong earthquake. Karpinsky volcano is not monitored with a seismic station. KVERT only uses satellite data to monitor Karpinsky volcano. |
