Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. Last week, USGS Hawaiian Volcano Observatory (HVO) scientists were closely monitoring earthquakes and ground deformation in the region southwest of Kīlauea’s summit. The increased unrest prompted HVO to raise the Alert Level/Aviation Color Code for Kīlauea to WATCH/ORANGE on January 31 as another intrusive event began beneath the surface.
