The coordinates are roughly: 34° 25' N, -118° 35' W

I am keeping tabs on this as I get a chance. I am aware that these areas exist. The reason for interest is the apparent heightened activity. I posted a previous comment regarding Placerita Canyon and the noticeable increased activity of a "bubbler" along the canyon trail. That one I am very familiar with as I hike the canyon often.

I would imagine - and I invite any commentary - that increased well activity (if it is) would be analogous to phenomena such as sand blows that occur in the course of and after a quake. Pressure is pressure, right?
