Re: The Next Big Quake - Rodgers Creek

Hi Todd,

Thanks for the kudo's, certainly more than we deserve. But yes, we did go to Berkeley a few weeks ago and ran our idea up the flagpole and found out we knew more than the individual we were talking to.

Actually, the person who knows the most about the Rodgers Creek Fault is Dr. David Schwartz of the USGS, however, he is in Argentina for a good long while. He is totally out of contact. Several years ago, he dug a trench near Sonoma Mountain, which is the largest peak in the chain. It revealed past earthquakes going back hundreds of years showing that this area had experienced large earthquake activity. Along with that, small detonations were done and they found that when an earthquake occurs on this fault system, the seismic waves travel first, up and down the system and then outward. I recall the news article saying, "more like a hot dog than a doughnut." That to was news.

Today there is no one actively researching the lower segment of this powerful fault system. Yes, it can deliver a 7.1, but it could be larger as well. Let's face it, it has been far to long since this segment of the Rodgers Creek has moved and therefore, when it goes, I hope I live in Colorado.

Now, one more little thing. Yesterday our local newspaper ran a story for earthquake preparedness month. It of course mentioned the Rodgers Creek Fault and pretty much said everything we've been saying all along, including the ABC's of preparedness. I hope many of our local residents took some time to read this article because it truly did convey the senario of what could happen around here when something large arrives. Possibly a real eye opening for many who don't know, those hills to our east are there because of seismic activity.
