How humans adapt to life in an area prone to natural disasters is an intriguing study for the social sciences. In this volume, experts from several disciplines explore the adaptation process of prehistoric societies in the volcanic Arenal region of Costa Rica from about 2000 BC to the Spanish Conquest at about AD 1500.

The data in this volume come from a survey of the region conducted with the latest remote sensing technology. Sheets and his coauthors have compiled a detailed record of human settlements in the area, including dozens of archaeological sites and a network of prehistoric footpaths that reveals patterns of travel and communication across the region. The Arenal peoples prospered in their precarious environment apparently by taking advantage of food and lithic resources, keeping population levels low, and avoiding environmental degradation. These findings will interest a wide interdisciplinary audience in anthropology and archaeology, earth sciences, technology, geography, and human ecology.

Scientists have long speculated on the impact of extreme natural catastrophes on human societies. Archeology and Volcanism in Central America provides dramatic evidence of the effects of several volcanic disasters on a major civilization of the Western Hemisphere, that of the Maya. During the past 2,000 years, four volcanic eruptions have taken place in the Zapotitan Valley of southern El Salvador. One, the devastating eruption of Ilopango around A.D. 300, forced a major migration, pushing the Mayan people north to the Yucatan Peninsula. Although later eruptions did not have long-range implications for cultural change, one of the subsequent eruptions preserved the Ceren site-a Mesoamerican Pompeii where the bodies of the villagers, the palm-thatched roofs of their houses, the pots of food in their pantries, even the corn plants in their fields were preserved with remarkable fidelity. Throughout 1978, a multidisciplinary team of anthropologists, archeologists, geologists, biologists, and others sponsored by the University of Colorado's Protoclassic Project researched and excavated the results of volcanism in the Zapotitan Valley-a key Mesoamerican site that contemporary political strife has since rendered inaccessible. The result is an outstanding contribution to our understanding of the impact of volcanic eruptions on early Mayan civilization. These investigations clearly demonstrate that the Maya inhabited this volcanically hazardous valley in order to reap the short-term benefits that the volcanic ash produced-fertile soil, fine clays, and obsidian deposits.
