Volcano Watch
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and colleagues.Quick View
Searchlava activity in HalemaÊ"umaÊ"u crater, at the summit of KÄ"lauea in Hawai‘i Volcanoes National Park. Summit tiltmeters have shown multiple deflation-inflation events over the past week.Seismicity is low. The sulfur dioxide (SO2)emission rate was most recently measured on March 21, when it totaled approximately 155 tonnes per day. For KÄ"lauea monitoring data, see https://www.usgs.gov/volcanoes/kilauea/past-week-monitoring-data-kilauea.
Mauna Loa is not erupting. Its USGS Volcano Alert Level is at NORMAL. Mauna Loa updates are issued on the first Thursday of the month.
Webcams show no signs of activity on Mauna Loa. Seismicity remains low.Deformation rates show inflation somewhat above background levels, but this is not uncommon following eruptions. SO2 emission rates are at background levels. For Mauna Loa monitoring data, see: https://www.usgs.gov/volcanoes/mauna-loa/monitoring-data.
There were twoearthquakes with 3 or more felt reports in the Hawaiian Islands during the past week: a M4.1earthquake 52 km (35 mi) ESE of NÄ‘Älehu at 7 km (4 mi) depth on March 26 at 6:36 p.m. HST, and a M3.9 earthquake 24 km (15 mi) WNW of Volcano at 4 km (2 mi) depth on March 23 at 5:04 p.m. HST.
HVO continues to closely monitor KÄ"lauea and Mauna Loa.
