11/10/2023 0 Comments Most recent volcano eruption 2018![]() By the end of November, satellite images showed that the lobes had advanced an additional 25-30 m along the S edge of the flow field and about 15 m SE. ![]() Seismicity was low with occasional detection of weak earthquakes.īy the end of the first week of November (figure 24), the flow field had extended more than 600 m E and about 430 m S from the vent into the remaining crater icefield. Elevated surface temperatures were sometimes identified in satellite images, and occasional steam plumes were observed rising from the lava flow. Weather clouds usually obscured satellite and webcam observations. This volcano in the central Aleutian Islands is monitored by the Alaska Volcano Observatory (AVO) using local seismic and infrasound sensors, satellite data, web cameras, and remote infrasound and lightning networks.ĪVO reported that slow lava effusion within the summit crater, centered about 1.5 km E of the peak and 300 m lower, continued during November 2022-April 2023. Since 23 July 2021, the Volcano Alert Level has remained at Watch (the second highest on a four-level scale) and the Aviation Color Code remained at Orange (the second highest on a four-color scale). This activity waned during January-April 2022, although slow lava effusion continued through October 2022. Continued lava effusion overtopped the summit crater wall and flowed down the N, S, and W flanks (BGVN 46:08, 47:05). Many Hawaiians participated in traditional practises during the Mauna Loa eruption, including singing, chanting and dancing in honour of Pele, the god of fire and volcanoes.Continued slow lava effusion in the summit crater during November 2022-April 2023įollowing minor explosive activity at Great Sitkin in June-August 2018 and June 2019, the first eruptions since 1974, an ash explosion on preceded the growth of a lava dome in the summit crater starting in mid-July. Volcanic eruptions have significant cultural and spiritual meanings for the native Hawaiians. “It was a beautiful eruption, and lots of people got to see it, and it didn’t take out any major infrastructure and most importantly, it didn’t affect anybody’s life,” Ken Hon, the Hawaiian Volcano Observatory’s scientist in charge, told Associated Press. Visitors to Hawaii Volcanoes National Park were able to observe lava from both eruptions at the same time during the twin eruption. The reason behind both the volcanoes ceasing at around the same time is still unclear. Around the same time, both volcanoes ceased to erupt. Since November 27, when Mauna Loa erupted for the first time in 38 years, Hawaii had two volcanoes spouting lava side by side. ![]() It last erupted in September 2021 and continued for 16 months.īefore its most recent lull in December, Kilauea had been erupting virtually nonstop for more than a year and was the scene of a massive eruption in 2018 that destroyed hundreds of houses. The volcano Kilauea is among the most active ones on the planet. The Hawaiian Volcano Observatory noticed a light in photographs and later concluded that Kilauea had started erupting, according to USGS.Īlso read: Will Tonga volcanic eruption affect global climate? Other dangers include Pele’s hair, which are tiny strands of drifting lava, and other delicate volcanic particles that can irritate the skin and eyes. Elements like sulphur dioxide can combine with the environment to form volcanic smog, which is dangerous to human health. The USGS warned locals that the high quantities of volcanic fumes may still be dangerous as they travelled downstream. The agency issued an advisory for locals and cautioned the aviation industry about the dangers of airborne ash.Īs of now, communities are safe since the lava from the volcano is now contained in Kilauea’s crater, a closed section of Hawaii Volcanoes National Park, tweeted Hawaii’s Emergency Management Agency. The eruption started Januafternoon at the volcano’s crater, according to a notice issued by the United States Geological Service (GSGS).Īlso read: Slowdown of continental plates linked to volcanic eruptions triggered mass extinctions: Study After a brief pause, Hawaii’s Kilauea volcano erupted again, spewing lava fountains and discharges of volcanic ashe into the air, according to officials.
