![]() No unusual activity has been noted along the volcano’s East Rift Zone or Southwest Rift Zone. Eruptive activity is confined to Halemaʻumaʻu crater within the summit caldera at Kīlauea. Geological Survey Monday, June 19, 2023, 7:21 AM HST (Monday, June 19, 2023, 17:21 UTC) KILAUEA VOLCANOĪctivity Summary: Kīlauea volcano is erupting. It offers a real “feel” for what the current eruption looks like–and also the manner in which the eruption is being confined to the depth of Kilauea’s deep caldera.HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE U.S. ![]() Check out this video of the most recent overflight. USGS scientists conduct regular observational overflights of the Big Island’s volcanoes. Geological Survey’s (USGS) Hawaiian Volcano Observatory (HVO) does a spectacular job of reporting on and updating its monitoring of the eruption. KILAUEA UPDATES ARE ISSUED REGULARLY BY USGS SCIENTISTS Plumes of smoke and gases are shown emanating from the pools of lava at the bottom of the Kilauea’s deep caldera. The caldera measures 2 miles by 2.5 miles across.Ĭloser look at the ongoing eruption deep inside Kilauea’s caldera in Hawaii’s Big Island. deep “caldera” or “crater” as seen in this frame from a USGS Hawaiian Volcano Observatory helicopter “fly-over” in recent days. Smoke from the lava can be seen emanating from this bottom of the more than 1,000 ft. Here’s what Kilauea’s CALDERA or “crater” looks like. The GOES WEST satellite in “parked” over the equator at an altitude which is MUCH HIGHER-22,300 miles above Earth’s equator. The Suomi satellite moves continuously from pole to pole as Earth rotates below–and it does it at an average altitude of 512 miles above Earth’s surface. On these images, Kilauea’s heat appears as small dots superimposed on a map of Hawaii’s Big Island. The folks at CIMSS (the Cooperative Institute for Meteorological Satellite Studies) at the University of Wisconsin-Madison have posted heat sensor imagery produced early on in the eruption back on June 8th and yesterday (Wednesday morning) from both the Suomi NPP polar orbiting weather satellite and from the much higher altitude GOES WEST geosynchronous orbit weather satellite 22,300 miles above the equator. WEATHER SATELLITES–LIKE THE COMPARATIVELY LOW ORBIT “SUOMI NPP SATELLITE–HAVE HEAT SENSORS WHICH ENABLE VISUALIZATION OF THE HEAT BEING RELEASED BY KILAUEA’S LAVA Many of the Big Island’s major tourist destinations are 100 miles from where the volcano is erupting. Any observed or predicted wind shifts are carefully monitored and reported to residents and the public there–but would generally impact only small areas. Gases Released By Volcanoes Can Be Dangerous And Are Monitored Closely.īut Hawaii’s persistent and wonderful easterly trade winds generally whisk these gases out over the open Pacific and away from the site. For reference, Honolulu and Pearl Harbor are on the island of Oahu–to the northwest of the Big Island. Here’s a look at where the BIG ISLAND and Kilauea are situated relative to the full Hawaiian Island chain. It’s one of five volcanoes on the Big Island. The KILAUEA VOLCANO is within Volcanoes National Park on the southeast side of Hawaii’s BIG ISLAND. From these sites, Kilauea’s eruption, which consists of plumes of molten lava surging high into the air at the bottom of the deep caldera, can be viewed safely from a distance. The Park is home to Kilauea and is located on the southeast side of the BIG ISLAND. The eruption began when I was on the Big Island last week and local media in Hawaii reported more than 10,000 visitors traveled to Volcanoes National Park observation sites in a single day. ![]() Instead Kilauea has attracted tourists and residents alike to the overlook observation sites from which it can be safely viewed. Thankfully, NO SUCH THING IS HAPPENING with the current eruption. THAT ERUPTION DID destroy homes and led to evacuations. In THAT eruption, an eight mile river of molten lava flowed from a crack or “fissure” in the Earth’s surface and flowed all the way to the Pacific. ![]() That’s VERY DIFFERENT from what happened when Kilauea erupted in 2018. It’s NOT FLOWING into the surrounding countryside. The towering walls of the volcanic crater confine Kilauea’s lava to the depths of this deep crater. The eruption is occurring at the bottom of Kilauea’s “caldera” or “crater”-which is more than 1,000 ft. That’s NOT WHAT’S HAPPENING with the current eruption. When many who are unfamiliar with Hawaii’s Kilauea volcano hear news that the volcano is erupting, images of 2,000+ deg lava flowing into the surrounding terrain may arise.
