A shallow earthquake swarm has been detected beneath the summit of Kīlauea Volcano, accompanied by significant surface tilt excursion, according to the Hawaiian Volcano Observatory. HVO scientists say resumption of eruptive activity at Kīlauea summit is likely imminent.
January was established as the Island of Hawai‘i’s annual Volcano Awareness Month in 2010 as part of an effort to increase understanding of Hawaiian volcanoes among residents and visitors. Important eruption anniversaries in January include the start of Kīlauea’s long-lived Pu‘u‘ō‘ō eruption on the middle East Rift Zone (1983–2018) and the 1960 Kapoho eruption. Until 2018, these were the two most destructive recent eruptions of Kīlauea.
The modern workhorse for ground surveying is terrestrial laser scanning (TLS) using light detection and raging (LiDAR) instruments. LiDAR may sound familiar to longtime “Volcano Watch” readers, because the basic technique was described in a November 2020 article that discussed an aerial LiDAR survey at Kīlauea. TLS surveys are similar, with a ground-based instrument emitting laser pulses and measuring their return times after reflecting off topographic features.
HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.
