When the Loma Prieta (San Francisco area) earthquake hit in 1989, my mom was in Los Angeles talking on the phone to someone she knew in San Francisco.

He said he thought they were having an earthquake. Many second later she felt it arrive, while they were still on the phone. Voice signals travel through phone networks a lot faster than P-waves travel through the ground.

Hmmm... I wonder if Verizon P-waves have better quality than AT&T P-waves. :rolleyes:

I briefly woke up and shrugged it off. Woke up in the morning thinking I had a dream about a mild earthquake and that I had long, flowing locks and was right about to close the deal.

We must have slept through it (or it wasn't strong enough in our area for us to feel it).

You would have felt it had you been up. 4.4, while not huge, is certainly big enough to get your attention. It woke my wife up, and we're quite a ways further from the epicenter than you are.

Wow, I must have been out cold then. I'm typically a very light sleeper.

I was once woken up by an earthquake when I was still living in Toronto.

Hehe, my british husband, not knowing how seasoned my California family is with earthquakes, sent my mother an email to ask her about it. Her response made us both laugh and since I know Q has met her, I'm posting it:

iBlue's mom said:
No, did not feel a thing. The whole local morning news was so annoying, blabbing about nothing, interviewing idiots so they could say in their room temperature I.Q.s what they experienced. I want death, carnage, & busted freeways before you interrupt our news with a quake reading not larger than a fart.

:D After the Northridge quake she nonchalantly walked up to my side of the house past all the broken and fallen stuff and pointed a flashlight at me and said with a hint of a smile, "Well that was pretty big!" No crap, mom! She's tough to shake up, as it were.

I think that the root question is not, whether or not they are better P-waves, but rather if they are in greater quantity over a wider area. :p

Love your mom's reply! :)

Same here in Japan. It needs to be pretty significant before we notice or get worried.

iBlue: I bet your mom just loved it when the local news stations started reading us random twitter messages like "we just had an earthquake!" over the air. :rolleyes:

The news stations seem to think that doing this makes them look cool. I think it's the opposite. If I wanted to get my earthquake news from tweets I wouldn't have turned on the TV!

Same here too. I just looked at the local "earthquake watch" site and I see that we had a 5.5 today, a 5.7 yesterday, and a 4.0 two days prior. I wasn't aware of any of them :p

:D Oh yes, I bet that did make her eyes go-a-rollin'. She was most disappointed in me for being a "twit" myself but I assured her I'm only a part-time twit.

Very much agree about that last part too.

I think the accuracy was good and that they correctly reported what a random person said on twitter. The question is WHY???
Tweets like hey the ground is shaking here are all that helpful and informative. But I guess it's quick.

As to "WHY???", now that's a good question. :)

Woah! We just went rock and rolling here. Did Southern California just have another quake?

Yes, it felt like the city was on ball bearings. Felt weird.

I'm sure there's a lot of damage near the border. Sad. Hope not too bad, though - but that is huge!

I certainly felt that one! That's exactly how it felt.

I felt weird- like I was dizzy for a few seconds. I was in a store, so I looked around, but no one else was reacting to it.

There were preshocks of magnitudes in the 3s and 4s in Mexico before the biggest jolt. Some sites are calling it 6.9, some 7.2.

We're having aftershocks on our side of the border, including a 5.1 near El Centro, CA. I wonder if the seismic waves had to go through immigration.

On no!
Reports from Disneyland security indicate that the park's rides have been shut down to be checked for damage, as standard procedure after any earthquake.​
