Overview

• The latest episode on Friday sent lava arcs about 100 feet within Halemaʻumaʻu and posed no threat to homes, with recent fountains trending shorter than earlier peaks.
• HVO’s Ken Hon reports a lower chamber is receiving magma at roughly 3.8 cubic meters per second, inflating the system and feeding an upper chamber that drives the vents.
• Scientists can estimate short‑term emergence days in advance using seismic and ground‑tilt sensors, yet the next phase could either taper at the summit or shift to lower vents as in 1983.
• USGS livestreams offer multiple camera angles as park visitation climbs; officials urge staying on marked trails, preparing for 10–12 hour episodes, and signing up for alerts due to gas and cliff hazards.
• This run of repeated summit fountains is the fourth such sequence in two centuries, following cycles in 1959, 1969 and 1983.
