What is the difference between a caldera and a pit crater?
A caldera is a large, basin-shaped volcanic depression, more or less circular, the diameter of which is many times greater than that of the included vents. A pit crater is a crater formed by sinking in of the surface; not primarily a vent for lava. 4. How much lava is erupted everyday from Kilauea? How deep is the lava from the current eruption? How many new acres of land have been added to the island? How many homes have been destroyed by the current eruption? The current eruption of Kilauea has destroyed 187 structures including the park’s Wahaula Visitors Center. The current eruption rate of Kilauea volcano is 250,000-650,000 cubic yards/day (200,000-500,000 cubic meters/day). That is enough to cover the floor of the caldera with a thin layer of lava every day or resurface a 20-mile-long two-lane road, like Chain of Craters Road, every day. Remember, the eruption has been continuous since 1983, that would make the stack of lava on the road about 20 miles tall! Fortunately, most of t
