With fortunate timing, we rode in the catamaran "Lava Ocean" to see lava spilling into the sea. The forest was burning behind it, and waves competed with lava--the water tried to freeze the lava and the lava responded by evaporating the water. The air was full of sulfur. A black sand beach decades old (at least) had been buried by new black rock in the course of ten days. We were glad that the boat had dual everything, so that we were not thrown into the melee. The captain kept a close eye on the breakers and ran us out to sea as necessary. We dipped out ocean water; it was hot.
