The eruption began with lava fountaining in the summit caldera (Moku\u02bb\u0101weoweo) at 23:21 HST on November 27, transitioning to vents on the Northeast Rift Zone (NERZ) by the next morning.  The dominant vent on the NERZ\u2014fissure 3\u2014was active for about 13 days, sending a lava flow to the north that stalled within 3 km of Daniel K. Inouye Highway.  The eruption ended on December 10, having covered a section of the Mauna Loa Observatory Road but otherwise causing no major damage.   \nDuring the eruption, the U.S. Geological Survey\u2019s Hawaiian Volcano Observatory (HVO) used nearly two dozen field-situated cameras to monitor and document the activity.  Several of these cameras were permanent and had been installed prior to the eruption, while others were deployed in the opening days of the eruption.  We used two main types of cameras.  First, we deployed \u201ctimelapse\u201d cameras around the eruption site.  These cameras did not telemeter their images and simply saved the data onto internal SD cards, requiring later retrieval.  Although not effective for real-time monitoring, these cameras are very compact and portable, providing excellent data for later research.  Second, we used several \u201cwebcams\u201d, which telemetered their images back to HVO in real time.  One of these webcams was a permanent thermal camera at the summit of Mauna Loa.  Several other webcams were portable cellular trail cameras deployed during the eruption.  The camera deployment built upon responses to recent eruptions at neighboring K\u012blauea volcano (Patrick and others, 2019; 2024). \nIn this data release, we provide images from the timelapse cameras and webcams used to monitor the 2022 eruption of Mauna Loa.  These data should be valuable for understanding the eruption dynamics and integrating with other monitoring data, such as seismic tremor.   \nReferences \nMulliken KM, Kauahikaua JP, Swanson DA, Zoeller MH. 2024.
