The USGS Hawaiian Volcano Observatory (HVO) detected an increase in shallow seismicity and localized ground deformation beneath the south rim of Halemaʻumaʻu crater, in Kīlauea summitʻs south caldera region. This activity highlights the dynamic and hazardous nature of the closed area in Hawaiʻi Volcanoes National Park, where changes can occur quickly, resulting in rapidly escalating hazards.
