Next one hit...5.1 this time, just happened.
Back to swaying at the Grand. New meaning to “rock-a-bye baby” !!
Yikes!

Long time San Diego resident here ... it is very common for earthquakes to present themselves in swarms.Question for California residents: Has there been such an intense series of aftershocks to a quake in the state's history before?
From what I have read about San Fran. in 1906 and 1992 as well as Northridge in '94, the aftershocks paled in comparison to the original, fading off considerably.
But this latest 7.1 quake, the third with the same epicenter of 5.0 or greater strength in two days, was felt as far away as Phoenix, apparently.
Any precedent to a series of quakes with such intensity?
The Northridge quake spawned over 1000 aftershocks with many of those negligible. However about 9 were in the 5-6 Moment Magnitude range, if I recall correctly when studying this particular event. As far as knowing the 1906 quake in San Francisco technology didn’t afford to recording this in high detail and population was much lower so hard to know. But in short these clustering events is an expected phenomenon of earthquakes.Question for California residents: Has there been such an intense series of aftershocks to a quake in the state's history before?

Stay safe everyone! Any advice for an Eastcoaster coming out there in a few weeks, staying in Anaheim and LA?
Depending on how strong it is, not everyone feels them, so one could happen, and you may not even know. If you do feel one, just get away from the cabinets or things that could fall.We felt it in our hotel room! I didn't know what to do for safety. I'm really worried about another one......
Yes that was my concern! Good luck!We felt it in our hotel room! I didn't know what to do for safety. I'm really worried about another one......
Thank you!!!Some quick tips for CA visitors who are not familiar with being in an area prone to earthquakes:
- if you're in a building, get under a table, desk, or better yet...stand in a doorway during the earthquake.
- if you're in a building when an earthquake starts, do not run outside. Why? Breaking/falling glass from windows.
- buildings in CA are built to earthquake building codes. This means that they WILL move a bit during an earthquake, but will likely not fall off of their foundations or other catastrophic stuff like that.
- there's a reason why you usually don't see many newer buildings in CA made out of brick.
- an earthquake in CA can pretty much happen at any time.
- you won't be able to feel most earthquakes.
- if you're close to the epicenter, most people can feel an earthquake starting around the 3.0 mark.
- the farther away you are from the epicenter of an earthquake = lesser effect & less damage.
- the possibility of earthquakes is, generally speaking, NOT a reason to not travel to CA. Your odds are much better of being injured in an automobile accident.
It isn’t unheard of.
We were waiting in line to go into Oga’s when this last one hit. We’re hoping all the rides open back up soon. I think that was the second longest earthquake I have experienced as an adult. The 2010 Baja Easter earthquake was the same magnitude and lasted 89 seconds.
Technically these aren’t aftershocks. The Jul 4 was foreshock and the 7.1 was the main quake- for now. Subject to change if there is another quake. As such the history books will never show an aftershock stronger than the main event. (I’m a CA native and didn’t know this until yesterday!)Question for California residents: Has there been such an intense series of aftershocks to a quake in the state's history before?

But always be cautious going outside after an earthquake as prior posters mentioned. Many injuries happen during and post quake from exiting buildings in a panic without realizing that the external decorative parts of the building can be damaged, and generally will be damaged first, thus having the risk of injury. I would generally ask if unsure if it is safe to exit a building, especially if not local. Also other major sources of injury are improperly secured furniture that can tip over. My guess would be that DLR has all furniture properly secured but under a table is safest as mentioned.If you're in a hotel, have your shoes and important papers in a bag ready to go outside if needed
Not as frequently felt as CA, but we get them in Washington, in the Puget Sound area. The last biggie was the Nisqually in 2001, 6.8. I've gotten under desks and dove into doorways a few times.
This is correct though very different animals. The destruction at the Vancouver/Seattle one will be very devastating if the “big” one happens during our life time. One thing to remember “soon” for earthquakes is on a geological scale so soon for the earth is a much different measure than a human’s scale of time. So it’s possible to occur this generation the next or a few down the line of more. This is the same for the LA basin. Also these aren’t predicted they will occur it’s just a question of when, which can not be forecasted beyond a geological scale, which even that is a lot of guessing.EDITED TO ADD: I've read that the "big one" which is predicted to hit Vancouver/Seattle some day will be much worse than the "big one" which will one day hit California.
