A new lava dome at the summit of Fugendake is viewed from the air on 20 May 1991, the first day of dome growth that continued until February 1995. The blocky, light-colored dacitic lava was extruded into Jigokuto crater, which formed during explosive activity on 17 November 1990, the first day of the 1990-95 eruption. Forested areas around the vents have been defoliated by the explosions, but at this early date undamaged forest remains in the background.
