Paul,

I am sorry to hear about your loss. :eek:

This is all that matters. "Sport" and I know many, many others in your area and they suffered quite a material loss as well. We hope you and "M" soon recover from this event.

Kudos to the staff at the ER at Queen of the Valley MC!! Bravo Zulu!! :thumbsup: :thumbsup:

We were north of Truckee at the time of the quake. We bagged two peaks (report coming) that weekend. We didn't hear about the quake until she logged on to FB after eating a late lunch in Truckee.

Vaca Maverick woke up and thought of going outside with the dogs, but the movement soon stopped. The only effect at our home was a swaying of the chandelier in the dining room. :)

A short quadcopter video of the damage:

Good luck Napa!!

Thanks,

By moving, I presume this means "creeping", which means steadily moving even without an earthquake. The Hayward is in fact one of several faults that are creeping but there are very few structures other than roads or curbs that cross it and are impacted by the creep. It's the shaking from earthquakes (rather than the fault displacement) that we really have to worry about. The Hayward, Calaveras, San Andreas, Rodgers Creek etc. and other faults will produce damaging earthquakes in the future. This earthquake should alert folks to add this somewhat ill-defined trend of various faults (West Napa, Carneros, Southhampton, Franklin, Lafayette, etc.) to the list of faults we have to plan for earthquakes on. We don't foresee being able to "forecast" earthquake occurrence, but our increasing knowledge of the earthquake sources should allow for better preparation, which is ultimately the best medicine for minimizing our losses.

September 7, 2014 Parched Napa Valley Creeks Bubbling With Streams Thanks To The Recent Earthquake

Fresh spring water was recently seen flowing in streams that traditionally went dry during this season in the Napa Valley.

Solano County’s Green Valley, an oasis in a canyon that was parched by drought only two weeks ago, has witnessed a miracle around the region owing to the strong earthquake the region had to bear. Where brooks usually ran dry during this time of the year, spring water can be seen trickling down trails and sprouting out of rocks, reported CBS.

Napa valley was subjected to a mighty jolt last month, when the region experienced a powerful earthquake measuring 6.0 on the Richter scale. As nature would have it, it turns out that the earth’s mighty shifting, which caused about $400 million in damage to Napa, Sonoma, and Solano counties, also mysteriously forced groundwater to the surface and into several dry or nearly dry creeks and streams in the region.

Speaking about the same, Mark Witherspoon, the reservoir keeper for two of Vallejo’s key sources of water, Lakes Madigan and Frey, said, “This was never wet before.”

He was referring to the Green Valley canyon and pointing to a bubbling, burbling fissure. Torrents of water have also been flowing down Wild Horse and Green Valley creeks and another unnamed waterway in the hills southeast of Napa and northwest of Vallejo since the August 24 quake.

A relief and bonanza for the drought-plagued Vallejo: The sudden upsurge of spring-water has certainly proven to be good news for the draught-stricken Vallejo. Officials for the the region’s water supply had to build an emergency pipeline from Lake Berryessa in the spring, after authorities learned that their supply of Sacramento-San Joaquin River Delta water was being cut off.

Normally Dry This Time Of Year, Wild Horse Creek Is Suddenly Flowing With Water

However, the liquid infusion, which some locals have taken to calling “miracle water,” bubbled up within the 1,500-acre watershed. Vallejo has exclusive rights to use this miraculously filled-up reservoir.

Solano County isn’t the only place getting an unexpected refill of their reservoirs. Local geologists have confirmed that at least four other, mostly dry waterways in Sonoma and Napa counties have seen big surges of water since the earthquake, reported The Press Democrat.

Explaining the phenomenon, Tom Holzer, a hydro-geologist with the U.S. Geological Survey, said, “This phenomenon is commonly reported after earthquakes. Earthquakes can cause fissures in the rock that bring up groundwater.”

Earthquakes usually cause destruction and wreak havoc. However, this quake brought relief to the draught-stricken region and alleviated water woes of the residents of Napa valley.
