Gas-and-steam plumes rise above a lava flow advancing into the Sea of Okhotsk on the NW flank of Alaid in 1972. The flow, which originated from NW-flank fissures, traveled 1 km and created a new 1 km2 peninsula. The 1972 eruption began with explosive activity on 18 June from a 2-km-long fissure and transitioned lava flow extrusion beginning 21 June.
