Pavlof 1983/7

Start: July 11, 1983 [1]

Stop: July 18, 1983 [1]

Event Type: Explosive

Max VEI: 2 [2]

Event Characteristics:
  • Tephra plume [1]

Description: From Miller and McNutt (1986): "An increase in seismic activity was recorded in mid-July 1983. Seismicity remained at background levels until 11 July. During the 24-hour period beginning at 1500 on the 11th, 6 explosions were recorded at a Lamont-Doherty seismic monitoring station near the volcano. The number of recorded events increased to 55 for the same period on 12-13 July, and to 150 on 13-14 and 14-15 July, then decreased to 120 on the 15-16th, 38 on the 16-17th, and 19 on the 17-18th, returning to background after 1500 on 18 July. During the period of increased seismicity, approximately half of the recorded events were low-frequency events.
"At 1549 on 15 July, a thermal infrared image from the NOAA 7 polar orbiting satellite showed a bright spot over Pavlof and an elongate plume extending approximately 150 km to the E."
