No significant activity was detected at Haleakalā Volcano during the past month. HVO seismometers recorded 2 small-magnitude earthquakes (below M3.0) in the vicinity of the volcano. This earthquake count is on par with previous months. The continuously recording Global Positioning System (GPS) instrument atop Haleakalā (MAUI) recorded no significant deformation.
Background: The most recent eruption on Haleakalā was probably between A.D. 1480 and 1600. Haleakalā Volcano is monitored by a continuous GPS instrument and seismometer located near the southwest edge of the summit crater. Key sites on Haleakalā are resurveyed using GPS receivers every few years to detect any changes in the volcano's shape.
