Cascadia update: July 23, 2022 …
Here is the latest on the trigger area of this event, Hollister. I have a picture of all earthquakes in the local area for the last year of time. As you can see this area looks like it is primed for release. But if you notice the major fault line, San Andreas fault, kind of stopped it activity north of the area in question. The Hayward and Calaveras fault lines seems to be taking all of the displacement energy from Hollister and north of it. This is putting undue stress on the San Andreas fault line. The good news, if that could actually be used here, there has not been too many larger quakes, that being more than 4.0.
This I would consider is an increase of earthquakes since the first of the year, as suggested by the C’s. This could be exponentially more in the future, that we will have to wait and see.
Hollister, Fair activity. Palo Alto, minimal activity. Imperial, large amount of activity around this area + a mud volcano to the south. Ukiah, scattered activity (nothing larger than 3.0). Eureka, way past the point of being ready (this area is ready to blow). Point Mendocino, very minimal activity. Monterrey, activity out in ocean/minimal activity. Offshore San Luis Obispo, very low activity. Capistrano, large amount of activity north of area/nothing larger than 4.0. Carmel: almost nothing for activity.
Areas of large concern in the last month starts with the Los Angeles/San Bernardino area and goes south and south-east over to the Salton Sea. Next is the area north of LA where it has been shaking still since their main event years ago. Then the large group around Mono Lake which is always seeing aggressive shaking (Caldera making noise). And more local to me is the geysers in Sonoma County where they are feeding underground steam fields with treated sewage water to keep them steaming. (Of note: Mt. Konocti, a mud volcano north of the steam fields, is seeing land sinking several homes in the area just south-east of the mountain. Old lava tubes are possibly collapsing? The mountain is not showing any other signs of abnormal activity.)
In conclusion, I expect that the activity that I am seeing is more than normal but obviously not enough to trigger this event. We are still in a holding pattern as I expect that this current earthquake activity will exponentially increase from where we are today. Still watching and waiting, Haiku …
