On August 24th at about 3:30 a.m. I was awoken by a rattling of clay roof shingles, the crashing of glass, and the shaking of walls. I had just arrived earlier that evening to Napa Valley after spending the week relaxing in Lake Tahoe, California. What an unusual welcome, a 6.0 earthquake! I had been in one earthquake before, but this one you could really feel. It was an unique experience since the last earthquake in Northern California as strong as this one occurred 25 years ago in 1989 during the World Series (measuring at 6.9). Scientists use a machine called a seismograph to measure the earth’s vibrations and use a scale called the moment magnitude scale. Earthquakes happen somewhere in the world everyday. On Tuesday, the grape harvest began. I hope the grapes were able to stay on their vines.
