Halemaʻumaʻu Crater

Halemaʻumaʻu Crater is a large volcanic crater located within Kīlauea's summit caldera on Hawaiʻi's Big Island. Formed by past eruptions, it measures about 2 miles across and 1,500 feet deep. The crater often contains a lava lake that periodically erupts, creating spectacular displays of flowing lava and volcanic activity. It is a key site for studying volcanic behavior and is part of Hawaiʻi Volcanoes National Park. The crater's activity can change frequently, influenced by underground magma movement, making it a vital indicator of volcanic health and potential eruptions in the region.
