The Quake That Drained the Desert

On May 3, 1887, an earthquake struck near the U.S.-Mexico border. Forty-three people died in Bavispe, Mexico; sixty miles north in Arizona, buildings swayed and a few collapsed, but no one was killed. Today, every person in southern Arizona lives with the underground aftermath of this earthquake: a drained aquifer. The estimated 7.4 magnitude earthquake created a sixty-two-mile rupture, the longest known surface rupture by a normal fault. The Quake That Drained the Desert tells the story of the men who investigated the earthquake: a doctor and photographer from Tombstone and an engineer from Mexico. Reynolds retells the terror of the survivors while exploring the ways the earthquake continues to shape water use and legacies in the greater Southwest. In this rigorous and gripping narrative, Reynolds unearths the aftermath of the quake, showing how it dramatically altered aquifers in southern Arizona and changed rivers that ensured the prosperity of two Mormon communities in southern Arizona and Mexico. With an eye to the present, this book asks us to consider how this underexamined quake marked the beginning of the water crisis in the region today, compacted by a century of groundwater pumping for agriculture, mining, and urban uses. As local governments and nonprofit organizations on both sides of the border now work to restore streams for wildlife habitat and flood control, they also hope to preserve water supplies for future generations.
