About The Cover

Lava flow after eruption of Mauna Loa Volcano, March 1984. Lava flows advanced nearly 20 kilometers in about 5 days toward the city of Hilo, largest city on the island of Hawaii. The flow slowed and stopped about 8 kilometers from nearest buildings on city's outskirts. All eruptive activity ceased by early April 1984. See page 196. [Scott Lopez, National Park Service]
