1 00:00:04,170 --> 00:00:13,246 On November 28, 2022, Mauna Loa, the world's largest active volcano, erupted. 2 00:00:13,246 --> 00:00:17,817 This was the first time Mauna Loa has erupted since 1984. 3 00:00:19,419 --> 00:00:25,291 Located on Hawaii's Big Island, 4 00:00:25,291 --> 00:00:30,630 the volcano began spewing ash and debris after a series of earthquakes. 5 00:00:32,165 --> 00:00:38,004 NOAA satellites captured the eruption, 6 00:00:38,004 --> 00:00:43,143 lava flow, ash plum, and sulfur dioxide emissions. 7 00:00:43,610 --> 00:00:48,681 Imagery from GOES-17 and GOES-18 helped NOAA's National Weather Service 8 00:00:48,681 --> 00:00:54,087 monitor the eruption and volcanic plumes in near real-time. 9 00:00:54,087 --> 00:00:59,592 This data allowed forecasters to observe the hottest areas 10 00:00:59,592 --> 00:01:04,564 of the lava field and emissions of ash and vapor. 11 00:01:08,001 --> 00:01:16,609 NOAA-20 and Suomi NPP captured imagery of the eruption at night. 12 00:01:19,546 --> 00:01:25,385 NOAA satellites monitored sulfur dioxide emissions from Mauna Loa, 13 00:01:25,385 --> 00:01:30,590 which can create airborne health hazards and case damage to crops. 14 00:01:33,827 --> 00:01:38,064 Mauna Loa has erupted 33 times since 1893, 15 00:01:38,064 --> 00:01:41,501 making it the world's most active volcano. 16 00:01:45,405 --> 00:01:53,446 When a volcano erupts, NOAA satellites play a crucial role in detecting volcanic activity, alerting nearby communities, 17 00:01:53,446 --> 00:01:59,619 and monitoring the hazards associated with eruptions. 18 00:01:59,919 --> 00:02:02,388 Earth From Orbit: Mauna Loa Erupts for First Time Since 1984 19 00:02:02,388 --> 00:02:03,623 Additional imagery from CIMSS. 20 00:02:03,623 --> 00:02:04,858 Mauna Loa footage courtesy of USGS. 21 00:02:04,858 --> 00:02:06,025 NOAA Logo 22 00:02:06,025 --> 00:02:07,127 NASA Meatball 23 00:02:07,127 --> 00:02:08,228 CIRA Logo
