Alaid, a stratovolcano, has erupted at least ten times since 1790.

The most recent eruption was in 1986. The 1790-1793 and 1981 eruptions were large (VEI=4).

The plume from the 1981 eruption reached heights of about 7 miles (12 km) and was observed by satellites.

Alaid erupted again in December of 1996.

This photo from the Space Shuttle looks to the southeast. The Kamchatka peninsula is at the bottom of the photo.

Shumshu, the first island south of Kamchatka, does not have any active volcanoes.

The volcanoes of Ebeko and Chikurachki, two of the most active volcanoes of the Kurile arc, are on Paramushir, the second island south (partial covered by clouds).

Agua de Pau, a stratovolcano with a caldera, erupted in 1563 and 1564.

The 1563 eruption was at the Cerro Qurimado vent on the northwest flank of the caldera.

The eruption lasted almost a month and was initailly Plinian and later produced lava flows that caused some damage.

The 1564 eruption lasted only two days and was near Lagoa do Fogo caldera. It may have been a phreatic eruption.

Thick pumice deposits on the flank of the volcano are probably the result of caldera-forming eruptions.
