Kilauea — R3cam Halemaʻumaʻu Rim

This USGS camera (R3) monitors a stretch of Kīlauea's rift zone on Hawaii Island, part of the continuous instrument network the Hawaiian Volcano Observatory uses to track where magma is moving. Kīlauea's rifts are lines of structural weakness radiating from the summit; when pressure builds, eruptions often break out along them rather than at the top. The view shows the lava terrain of the rift, where early signs of renewed activity — ground cracks, steam, incandescence — would appear. Conditions vary with elevation and the trade winds. Within Hawaiʻi Volcanoes National Park; Hawaii does not observe daylight saving.
