Alaid Volcano, northern Kurile Islands, USSR (50.80°N, 155.50°E). All times are local (GMT+11 hours). A strong eruption from Alaid, located on an uninhabited island in the Kurile group, apparently began during the morning of April 28. Clouds obscured the area until about 0915, when weather satellite imagery revealed a distinct eruption plume that grew steadily for the next 2½ days. Microbarographs at Kushiro Weather Observatory (about 1250 km SW of Alaid) recorded three distinct pressure waves on April 28: at 1143 (0.5 mbar), 1153 (0.2 mbar), and 1340 (0.8 mbar).
