Kīlauea Volcano — Fissure 8 Lava Fountain
As of 6:30 a.m. HST today, fissure 8 continued to feed a vigorous channelized lava flowto the east of the vent. Overnight, fountain heights were generally 40–50 m (130-160 ft) high, with occasional bursts up to 60 m (just under 200 ft) high. Fallout from the fountains has built an asymmetric cinder-and-spatter cone around the vent, with the southwest side of the cone slightly higher (about 115 feet) than the northeast side (about 65 feet). This asymmetry reflects the prevailing trade winds, with more lava piling up on the downwind side of the fountains.
