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.
