pumice curl around L’Esperance Rock in this satellite image collected on August 24, 2012. Pumice is light gray, water is near-black, and the sparsely vegetated island is red in the false-color image.

erupted in mid-july by the Havre Seamount, an underwater volcano about 50 kilometers (30 miles) to the northwest.
