KÄ«lauea Volcano is not erupting and its USGS Volcano Alert level remains at NORMAL (https://volcanoes.usgs.gov/vhp/about_alerts.html). Updates for KÄ«lauea are now issued monthly.
Kīlauea monitoring data have shown no significant changes in volcanic activity over the past week. Rates of earthquake activity or seismicity across the volcano remain largely steady with three periods of increased microseismic activity each lasting a couple of days. Sulfur dioxide emission rates are low at the summit and are below detection limits at Puʻu ʻŌʻŠand the lower East Rift Zone. The pond at the bottom of Halema‘uma‘u, which began forming on July 25, 2019, continues to slowly expand and deepen.
Mauna Loa is not erupting. Its USGS Volcano Alert level remains at ADVISORY. This alert level does not mean that an eruption is imminent or that progression to an eruption is certain.
During the past week, approximately 147 small-magnitude earthquakes (nearly all smaller than M2.0) were detected beneath the upper elevations of Mauna Loa. Most of the earthquakes occurred at shallow depths of less than 5 km (~3 mi) below ground level, but a couple were as deep as 12 km (~7.5 mi).
Mauna Loa updates are issued weekly. For more info on the status of the volcano, please go to: https://volcanoes.usgs.gov/volcanoes/mauna_loa/status.html
HVO continues to closely monitor both KÄ«lauea and Mauna Loa for any signs of increased activity.
