      Earthquake!

      Epicenter was only ~1,450 feet away..., but ~2Km deep!  Luckily it was only ~2.1.  Still makes a nice jolt.

       Probably cracked the driveway.

      Hope nothing serious Todd. Went through a shaker once. I was in junior college and the New Madrid moved after we got our of church on Sunday. It is a funny feeling. Never thought there would be one in Mississippi but it was.

      As I figured.  The small crack in the driveway expanded and opened up a bit.

      Man Todd, If I had a fault running through my property I think I'd have to tempt fate and run some track or better yet a little bridge over it. I know your pike is in the back and not necessarily close to your drive but maybe a spur? Call me devious...

      No, my pike is in the front yard and abuts the cracked driveway.

       I have no idea why this appears here.

      El Modeno's.

       

      ABSTRACT: The El Modeno Fault in Orange County, California: New Evidence for Holocene Activity

      The El Modeno fault in north-central Orange County has long been suspected of being active in accordance with the guidelines of the Alquist-Priolo Special Studies Zones Act of 1972. The El Modeno fault was uncovered during a preliminary geotechnical investigation for a proposed shopping center development just south of the intersection of Chapman Avenue and Newport Boulevard in the city of Orange, California. Topsoil observed within the shear zone of the fault appeared to be visibly offset. As a result of this discovery, an Alquist-Priolo fault investigation was initiated, involving fault trenches excavated across the site. Close examinations of the fault trace exposed in the trenches conclusively showed that the surficial soil horizon was truncated. Previous geologic and geotechnical investigations in the vicinity of the site have failed to document undisputed evidence for Holocene activity (truncated geologic units proven to be less than 11,000 yr old) along the El Modeno fault. This lack of previous conclusive evidence is perhaps due in part to the general lack of datable organic material in Holocene soil horizons, and the distribution of displaced materials over a broad zone, a trait characteristic of reverse/right-lateral strike-slip displacement such as that along the El Modeno fault. Carbon-14 radiometric dating of the truncated soils revealed that surficial soils at this site are less than 2500 yr old. Thus, the El Modeno fault should be considered active in accordance with the present guidelines of the Alquist-Priolo Special Studies Act.

      The potential zoning of this fault through urbanized areas of Orange County will undoubtedly create some zoning restrictions and may have implications for future planning and redevelopment activities in the area. Earthquakes, such as the recent one in Landers, California, have provided us with interesting insight into the behavior of fault ruptures through both urbanized and unimproved land. Additionally, examination of the behavior of the Landers rupture may have serious implications for our interpretation of expected fault kinematics along faults with similar types of displacements directly related to the El Modeno fault, such as the Peralta Hills thrust and the Whittier-Elsinore fault zone.

      Saint Andrew's fault.  

       

      St Andrew is reputed to have been the gentlest of the apostles.  

       

      Go figure.

      "Whose fault?" It's got to be Trump's fault because Bush's fault is in Illinois.

      Now now Tom. That sounds like "political speak" and that's a no no on LSC.

      Not St. Andrew's, Steve, it's San Andreas. Got your seismological facts in order. 

      Of course, Jimmy Buffet wrote/sang, "It's my own damn fault," depending on which stanza of the song we're talkin' about. You know, "Some people say that there's a wo-man to blame, but I know...." etc.

      I blame bush, if it wasn't the bushes then those trees look pretty suspicious.
