Photo and Video Chronology — V1cam maintenance, a new webcam, and new maps of unrest

By Hawaiian Volcano Observatory May 2, 2024

HVO staff performed some routine maintenance on the V1cam at Kīlauea summit. And, new maps show the recent unrest near Kīlauea summit.

Despite a significant increase in small earthquakes at the summit and upper East Rift Zone in recent days, activity at the surface was quiet On May 1, 2024. This photo shows the floor of Halema‘uma‘u, at the summit of Kīlauea, which last erupted in September 2023. Weak outgassing plumes originated from several spots on the crater floor, and this has been typical during quiet periods. USGS photo by M. Patrick.

This photo shows the southwest portion of Kaluapele (Kīlauea's summit caldera). In the lower right corner of the image is the cone formed during the June 2023 eruption. This cone hosted impressive lava fountaining that supplied lava through a narrow channel into the lava pond in the lower left portion of the image. USGS photo by M. Patrick.

May 2, 2024—Summary map of recent unrest at Kīlauea volcano

Map of earthquake locations on volcano — This map depicts recent unrest at Kīlauea volcano. Yellow circles mark the locations of approximately 1,600 earthquakes that have occurred between April 27 and May 2, 2024, as the upper East Rift Zone reacts to pressurization of magma chambers beneath the summit region of Kīlauea. Most earthquakes have been smaller than magnitude-2, with locations clustering in an area known as the upper East Rift Zone or East Rift connector. The upper East Rift Zone area saw several eruptions in the 1960s and 1970s, which are labelled and shown in purple. Most recently, in November 1979, a brief one-day eruption occurred in and near Pauahi crater. In July of 1974, a three-day-long eruption began in Keanakāko‘i Crater, with east-west oriented fissures subsequently opening within Kaluapele and southeast towards Luamanu Crater. A month-long eruption in November 1973 extended from Pauahi Crater east towards Pu‘uhuluhulu. And, a day-long eruption in May 1973 extended from about a half a mile (1 km) west of Hi‘iaka to Pauahi Crater.

May 2, 2024—New webcam to monitor the upper East Rift Zone

This temporary webcam, deployed with permission from Hawai‘i Volcanoes National Park, is located near Maunaulu. The view is to the northwest, of the upper East Rift Zone.
