The continuously recording Global Positioning System (GPS) instrument atop Haleakalā (MAUI) recorded no significant deformation during this time.

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: Kilauea (NORMAL/GREEN), Hualalai (NORMAL/GREEN), Mauna Kea (NORMAL/GREEN), Loihi Seamount (UNASSIGNED/UNASSIGNED).
