Kilauea volcano update: new spatter cone in SW crater wall

The effusive eruption within the Halemaʻumaʻu crater remains active.

The fountaining continues in the summit caldera by numerous small fountains on the western crater floor area and in the southwestern wall of the pit crater.

The ongoing spattering in the SW wall, which has been building a new steep-sided spatter cone (also called a hornito currently) above the eruptive fissure, is visible in the live stream here. Emissions of incandescent, fluid lava by fountaining and lava flows feeding the westernmost part of the crater floor.

Multiple active eruptive vents, effusing lava flows, cover a broad part of the western half of the Halemaʻumaʻu crater in a horseshoe-shaped uplifted area.

A much smaller area of the eastern portion of the crater floor remained active during the night on 8 June.

The active lava lake is centered within the uplifted area and fed by a vent in its northeast corner. The level of the central lava lake has increased by approximately 1.5 meters (5 feet), as measured by laser rangefinder.
