HAWAIIAN VOLCANO OBSERVATORY MONTHLY UPDATE
U.S. Geological Survey
Thursday, February 7, 2019, 10:10 AM HST (Thursday, February 7, 2019, 20:10 UTC)


HALEAKALA VOLCANO (VNUM #332060)
20°42'29" N 156°15' W, Summit Elevation 10023 ft (3055 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

No significant activity was recorded at Haleakalā Volcano in January. One earthquake, a M2.3 event at a depth of 13.5 km (8.5 mi) below the ocean surface, was detected off the southeast flank of the volcano on January 14. The continuously recording Global Positioning System (GPS) instrument atop Haleakalā recorded no significant deformation over the past month.

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 a 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.


This notice contains additional volcanoes not displayed: Mauna Loa (NORMAL/GREEN), Hualalai (NORMAL/GREEN), Mauna Kea (NORMAL/GREEN), Lo`ihi (UNASSIGNED/UNASSIGNED).
