Agrigan is the highest of the Marianas arc volcanoes, seen here from the south. The island is 8 km long and its summit is the top of a large 4-km-high submarine volcano. The summit caldera is 1 x 2 km wide and 500 m deep, and the vegetated flanks consist almost entirely of pyroclastic deposits that are more than 100 m thick on the SW flank.
