Elevated seismic activity gradually died down in frequency of occurrence and intensity, over the course of 40 minutes. Locations of these earthquakes are spread broadly beneath east side of Halemaʻumaʻu crater and the south caldera. All of the detected earthquakes have been less than magnitude-2, with most being magnitude-1 or smaller.  ... [read more] ... [show less] This is the third small swarm of earthquakes beneath Halemaʻumaʻu crater since the end of episode 40.  The first swarm began at 12:40 a.m. HST and lasted for 30 minutes on Tuesday, January 13. It was followed the next day by a second swarm around 9:10 a.m. HST, and lasted less than 30 minutes on Wednesday morning, January 14. The first and second swarms both had magnitude ranges similar to the third. Most of the earthquakes seem to be occurring around the shallow Halemaʻumaʻu magma chamber, some 1.5 to 4 km beneath the surface.  Most of the earthquakes are volcano-tectonic earthquakes that accompany crack opening due to magmatic pressure. Elevated seismic activity of these intensities have not been seen at the summit since the start of the eruption in December 2024. A small swarm did precede a new fissure opening in the wall of the Halemaʻumaʻu crater just to the south of the vents, at the start of episode 30. It is yet to be determined if these swarms after episode 40 will have an impact on lava-fountaining activity at the surface.Pavlof (Alaska Peninsula, USA): Increased seismic activity has been detected at the volcano and its alert status was raised to Yellow. The Alaska Volcano Observatory reports:"The rate of long-period earthquakes has increased at Pavlof Volcano since approximately 12:45 am AKST (09:45 UTC) on January 14. No eruptive activity or emissions from the summit have been observed including in clear webcam images from this morning. The earthquake activity represents an increase from background levels, therefore the Alaska Volcano Observatory is raising the Aviation Color Code and Alert Level to YELLOW/ADVISORY. This type of earthquake activity in the past has preceded eruptions, but also has ended without an eruption occurring. We will continue to closely monitor the volcano for signs of increased activity, as eruptions at Pavlof Volcano often occur suddenly with little or no warning.The last eruption at Pavlof Volcano occurred in 2021 and 2022, and consisted of small lava flows and low-level explosions primarily from a vent on the upper southeast flank. Larger ash-producing eruptions last occurred at Pavlof in 2013, 2014, and 2016 from a crater on the upper north flank."Popocatépetl (Central Mexico): The Centro Nacional de Prevención de Desastres (CENAPRED) reported that the eruption continued at Popocatépetl between 13 January 2026 (local) and 14 January 2026 (local).
