Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake, Volcano, LANDSAT and Water information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.
A helicopter overflight on September 17, 2024, allowed for aerial visual and thermal imagery to be collected at the middle East Rift Zone eruption site on Kīlauea. The eruptive activity continues with fountains active within Nāpau Crater and lava flowing on the crater floor, marking an eastward shift in activity compared to September 15. The scale of the thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures.
