Halema’uma’u is the crater within the caldera. It bottoms out at 3,412 feet above sea level, whereas the floor of the rest of the Kilauea caldera is higher at approximately 3,640 (the rim near the Volcano House is 3,980).
This crater’s most recent activity was in 1974. It really is a breathtaking feature of the caldera that looks similar to craters seen on the moon! This is all part of Volcanoes National Park on the big island of Hawaii.
