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

May 2, 2024
Map of earthquake locations on volcano

This map depicts recent unrest at Kīlauea. Yellow circles mark the locations of approximately 1,600 earthquakes that have occurred between April 27 and May 2, 2024. 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. This area is reacting to pressurization of magma chambers beneath the summit region of Kīlauea. 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.
