California isn’t the only state holding earthquake drills. Last week, Arizona held a practice run — preparing for some 400,000 evacuees from California fleeing “The Big One.” More than 1,000 agencies worked to set up emergency shelters on a softball field, medical facilities and food. Clearly, the impact of a major quake in California would have devastating impacts beyond our borders. How will you fare when a major quake strikes?  Contact us today for a free consultation about your building.

South Carolina Recalls 7.3 Temblor of 1886

A recent spate of earthquakes in South Carolina has the community talking about the potential for a major strike — one that could rival the Charlotte 7.3-magnitude quake of 1886 that killed 60 people.

Retrofits Offer No Guarantees, But They Are Proven to Work

Retrofits Offer No Guarantees, But They Are Proven to Work
