Too funny. My wife and I were sitting at our dinner table when I felt a small jolt. I thought one of out cats nudged my chair, and my wife thought I had bumped the table. Turned out to be this small quake of course. We live in Fremont

****REMINDER**** Every fire has the ability to be catastrophic. The wildland fire management environment has profoundly changed. Growing numbers of communities, across the nation, are experiencing longer fire seasons; more frequent, bigger, and more severe, fires are a real threat. Be careful with all campfires and equipment.

"I am a firm believer in the people. If given the truth, they can be depended upon to meet any national crisis. The great point is to bring them the real facts, and beer." --Abraham Lincoln

How fires get their names

Every year in California thousands of wildfires start throughout the state. In most cases, the dispatch center sending the initial resources to a wildland fire will designate a name for the fire, but the first on scene engine or fire official can also name the incident. Fires are usually named for the area in which they start – a geographical location, local landmark, street, lake, mountain, peak, etc. Quickly naming the fire provides responding fire resources with an additional locater, and allows fire officials to track and prioritize incidents by name. For example during the Southern California Fire Siege of 2003, the largest wildland fire in California history, the Cedar Fire in San Diego County, was named after the Cedar Creek Falls area where it started. The destructive Old Fire, which burned during the same time period in San Bernardino County, was named after the road along which it started - Old Waterman Canyon Road.
