Winemaker Tom Montgomery stands in wine and reacts to seeing damage following an earthquake at the B.R. Cohn Winery barrel storage facility on Sunday in Napa Valley.

Sunday’s 6.0 earthquake in Northern California dealt a structural blow, with particular impact on Napa Valley.  A warning from the Seismological Laboratory at UC Berkeley sent an alert about the temblor 10 seconds before the earthquake hit Napa Valley: the high-magnitude quake struck at 3:20am and left 89 people injured and 20,00 Napa residents without power.

Damage to structures in Northern California included the loss of winery reserves worth hundreds of thousands of dollars. The quake raises questions about how early warning systems can be made most effective as well as how buildings can be repaired and retrofitted to better withstand big earthquakes. How do you prepare for a quake?
