Kilauea (Hawai’i): (25 Aug) Episode 54 of lava fountaining in Halemaʻumaʻu crater at the summit of Kīlauea began at 10:30 a.m. HST on August 25 and continues as of this notice at 12:15 p.m. HST.

Based on HVO webcam views, the north vent lava fountain is reaching 500 feet (150 meters) above ground level, and its plume is reaching 17,000 feet (5,200 meters) above sea level. Ground-level sensors near the eruptive vents indicate that winds are blowing from the northeast direction, which suggests that volcanic gas emissions and volcanic material may be distributed to the southwest direction from Halemaʻumaʻu. The effusion rate from the north vent has reached approximately 260 cubic yards (200 cubic meters) per second, but it is expected to decline for the remainder of the episode.

Fuego (Guatemala): Explosive activity continues. The Volcanic Ash Advisory Center (VAAC) Washington warned of a volcanic ash plume rising to an estimated 15000 ft (4600 m), or flight level 150.
