Halemaʻumaʻu Crater (six syllables: HAH-lay-MAH-oo-MAH-oo) is a pit crater located within the much larger summit caldera of Kīlauea in Hawaii Volcanoes National Park. The roughly circular crater was 770 meters (2,530 ft) x 900 m (2,950 ft) prior to collapses that roughly doubled the size of the crater after May 3, 2018. Halemaʻumaʻu is home to Pele, goddess of fire and volcanoes, according to the traditions of Hawaiian religion. Halemaʻumaʻu means "house of the ʻāmaʻu fern".
The crater until recently contained an active lava lake. From 2008, when the current vent inside Halemaʻumaʻu crater first erupted, to April 2015, lava was present inside the vent, fluctuating from 20 to 150 meters below the crater rim. On April 24, 2015 molten lava in the vent, known as the Overlook Crater, became directly visible for the first time from the Jaggar Museum overlook at the Hawaiian Volcano Observatory, when the lava rose to an all-time high level since the Overlook Crater first opened. A few days later, on April 29, the lava started spilling over the rim of the Overlook Crater and onto the floor of Halemaʻumaʻu Crater, ultimately adding a layer of lava approximately 30 feet (9 m) thick to the crater floor.
For three years from 2015 to 2018 the lava lake level remained close to the rim, with a further minor overflow event in October 2016 and a significant one in April 2018 that covered a majority of the crater floor in new lava. n eIarly May 2018 the lava level in the Overlook Crater dropped over 700 feet and out of sight, resulting in explosions, earthquakes and large clouds of ash and toxic gas, causing closure of the Kīlauea summit area of the national park from May 10 to September 22. While the park visitor center and headquarters have reopened to the public, the crater is currently in a state of collapse that includes substantial portions of Kīlauea Caldera. The Jaggar Museum overlooking the crater remains closed. SOURCE: Wikipedia
