- The observatory noted spattering and volcanic tremor during the latest episode, with fountains measured near 12 meters while some reports cited roughly 6 meters.
- USGS activated an aviation orange status on Jan. 12 local time due to elevated gas and a volcanic column observed over the weekend.
- A plume near 20,000 feet was reported on Jan. 10, while recent lava remains confined within the crater.
- HVO continues heightened monitoring and public livestreams as episodic eruptions in this sequence typically last less than a day.
