Crazy to think its been 30 years since the Northridge quake. In that quake specifically I seen clips of Caltech at the time said it was on a previously unrecognized fault in the San Fernando Valley and was within the same general area as the 1971 Sylmar quake.
I moved to LA in 2001 and this is the first time watching these news clips. We have natural disasters literally everywhere nowadays, volcanoes in iceland, earthquakes in Japan, China, Turkey, flooding in Libya etc. wonder the big one is coming as so many magnitude 4 to 7 have been happening everywhere.
Expect the USGS and Caltech to release the current data on which Los Angeles area faults are at the highest risk of having a 6.7 and above quake in the next 20-30 years approximately. I remember the USGS said stuff about "The Next Hayward Fault" quake in Northern California is overdue for an earthquake and they had a probability very high in the range of decades. But then again between today and the next big one we will get hit with quakes on previously unknown faults. In an unrelated example the 2014 6.0 Napa/American Canyon quake took place on a previously unknown fault which later became known as the West Napa Fault once more data was released on that one. That quake warned Northern California that its not just the Hayward and San Andreas faults that pose a threat during a quake.
