Seismic Activity
Kīlauea Earthquake Swarm
Nearly 100 earthquakes shook Kīlauea's summit caldera on September 30, 2026, prompting the closure of parts of Hawaiʻi Volcanoes National Park. The seismic activity corresponds with a shallow magma intrusion within the summit region near the ongoing eruption site in Halemaʻumaʻu crater, with the strongest activity recorded between 8 p.m. HST on September 30 and 3 a.m. on October 1.
Japan Offshore Earthquake
A magnitude 5.6 earthquake occurred 74 km south of Yonakuni, Japan, on September 30, 2026, at 05:00 UTC at a depth of 11 km.
Kanlaon Volcano Seismic Alert (Philippines)
Volcanic earthquakes are raising eruption risk at Kanlaon volcano on the island of Negros in the Philippines. Voluminous degassing was observed rising from the summit crater, with elevated seismic activity recorded in early October 2026.
Volcanic Watch
Kīlauea Summit Eruption with Magma Intrusion
Kīlauea volcano entered an active eruptive phase on the night of September 30, 2026, with flames, spatter, and lava flows erupting from both the north and south vents in Halemaʻumaʻu at the summit. Simultaneously, a shallow east-west oriented magma intrusion developed within the summit caldera near the eruption site. The intrusive activity was strongest between 8 p.m. HST on September 30 and 3 a.m. on October 1.
The U.S. Geological Survey raised Kīlauea's Aviation Color Code to ORANGE and Alert Level to WATCH due to the ongoing unrest.
Global Volcanic Activity
Multiple volcanoes remained active worldwide during late September 2026, including Mount Etna, Santiaguito, Fuego, Semeru, Ibu, and Marapi. In Indonesia, new islands reportedly emerged near Krakatau following the September 4–6, 2026 eruption, with the public advised to maintain a 1 km safety distance from the volcano as of September 24. Alert Level for Krakatau remained at 2 (on a scale of 1–4).
