Volcano Watch: Sniffing out stealthy gas escape between Kīlauea’s eruptions
Kīlauea has erupted three times in 2023—January–March, June, and September—and has also experienced significant intrusive activity to the southwest of the summit since the beginning of October.
Volcano Watch: HVO’s ongoing recovery from the 2018 Kīlauea eruption
Communities on the Island of Hawai‘i continue to recover from Kīlauea’s 2018 lower East Rift Zone eruption and summit collapse as does the USGS Hawaiian Volcano Observatory (HVO). During the events of 2018, HVO instruments were lost, monitoring infrastructure was impacted, and HVO staff had to evacuate the observatory, which was damaged beyond repair.
Volcano Watch — Using the Ocean to Track Volcanic Activity at Kīlauea
The USGS Hawaiian Volcano Observatory has a number of seismometers in place across Kīlauea Volcano for monitoring volcanic processes and active fault movements. When magma is not moving within or erupting from Kīlauea, the oceanic microseisms appear on seismometers as a repeating and unchanged signal.
