On Nov. 27, 2022, residents of the Hawaiian Islands were alerted of an impending volcano eruption. Approximately an hour later, lava began to flow from Mauna Loa for the first time in 38 years, The New York Times reported. “Mauna Loa,” which is Hawaiian for “Long Mountain,” is one of the world’s most active volcanoes, according to a report from the U.S. Geological Survey. The volcano stretches over half of the Island of Hawai‘i and measures around 10.6 miles tall, the report said. According to the report, Mauna Loa’s first “well-documented historical eruption” was in 1843, and it has since erupted 33 times, most recently in 1984.
