Overview

• Kilauea volcano on Hawaii's Big Island erupted on May 25, 2025, with lava fountains reaching over 1,000 feet from the north vent in Halemaʻumaʻu crater.
• The eruption, lasting several hours, is the 23rd episode in the ongoing activity that began in December 2024 and remains confined within Hawaii Volcanoes National Park.
• High levels of volcanic gases, including sulfur dioxide, are being released, creating vog that poses respiratory risks to nearby communities and visitors.
• Volcanic debris, including 'Pele's hair,' thin strands of volcanic glass, can cause skin and eye irritation and is being carried downwind by strong winds.
• The USGS continues to monitor the eruption closely and provides livestreams of the activity, with no residential areas currently threatened by lava flows.
