Sorry, been busy, but need to store this info somewhere for future reference! A quick note, as I was driving home to San Jose last night on the I-5, somewhere between Pasadena and San Fernando, I was hit by some very loud strong screaming from off to my left. My first reaction was "ouch wtf"? And told my husband, "that is a fault over there, and it is NOT happy"! It was painfully loud and I scrambled to try and search on my phone as to what these hills I was looking at were? I had never paid much attention in this area before, never had a reason to! I was in the "Glendale" area, passing names such as "La Tuna" and "Tejunga"? It was very apparent the hills in question were a fault! The further to the NE end of the fault we got, where it looked like we would cross over it, the worse it got! From what I could tell on my phone I was right and it was the "Verdugo fault"! As we crossed it at its point it was like in stereo. By the looks of what I can see today on line it runs into the Mission Hills Fault and San Fernando Fault Zone at that point. And of course the USGS has it classified as "Not Active". We'll guess what USGS?!!! So...... not sure when or where or what but me thinks it is being stressed, and I didn't notice it on the trip down on Friday night? Or any other trip I've made through there in the last 2 years, and I've made a lot! Due to the proximity of past quakes like Sylmar, Northridge, and I'm sure I can think of others later, consider yourselves forewarned! Something down in that area is stressed and not very happy right now? Leaving a couple links here for my own future reference as I'd like to keep an eye on it! Oh, and if you do a search on the "Verdugo Fault" there is a PDF file with lots of info and pics on it. I may add some here later!
