The 2014 annual report for the Hawaiian Volcano Observatory
This report summarizes team activities and findings of the Hawaiian Volcano Observatory during the year 2014 in geology, geodesy, seismicity, and gas geochemistry. The eruption of Pu‘u ‘Ō‘ō continued into its 32nd year with flows active to the northeast of the vent. One of them, the June 27th lava flow, named for the date in 2014 that the flow started, advanced far and fast enough to threaten the town of Pāhoa and Highway 130 in the Puna District of the Island of Hawai‘i. In response, the alert level for Kīlauea was elevated from WATCH to WARNING on September 4, followed by the declaration of a State Disaster on September 5 and a National Disaster on November 3.
During 2014, renewed inflation and increased seismicity was detected beneath the summit and upper west flank of Mauna Loa. Although above background, the frequency and magnitude of the earthquakes remained at such low levels that, by year’s end, the four-tier alert level code for Mauna Loa remained at its lowest level—NORMAL. These changes were discussed in several Volcano Watch articles.
Hualālai, Haleakalā, Mauna Kea, and Lo‘īhi showed no signs of unrest during the year.
