s of 2020[ [update]], the lull in eruptive activity at Kīlauea continues and most of the park is open; however, some road segments and trails remain closed to visitors, while the Jaggar Museum of the Hawaiian Volcano Observatory is closed indefinitely. The Thurston Lava Tube (Nāhuku) was reopened to the public on February 21, 2020. Several large rockfalls were cleared and sensors were installed to monitor new cracks, along with improvements to water drainage and parking. The rockfalls and cracks had been caused by some of the 60,000 earthquakes recorded during the Kīlauea eruption.
