In san diego we had a 7.2 on april 4 2010 more powerful than Haiti. My furniture is still tied down. CNN didn't even mention it until 2 days later. Virginia and Colorado get a shake and CNN is right on it. Obviously some people are more important.
oh stfu. why don't you get over yourself and hope for the best on the east coast?? idiot
oh good lord. you're really complaining because was one quake was reported faster than another?
Yeah, but ya'all are supposed to get earthquakes.
yes NYC is always more important
OBVIOUSLY. The world moves here in the northeast.... just accept it.
could be that earthquakes are pretty much expected in the california region??Just a thought.
Don't feel bad, after Katrina lots of politicians said we ahould not rebuild our city beacuse it floods. There are ignorant people everywhere.
Because nether place gets major earthquakes........California has them all the time.........
Keep in mind that California's buildings are build to withstand higher earthquakes on the Richter scale. in Virginia, they use mortar, brick and other items that aren't as stable.
a 5.8 is pretty big there.
I think that right now is not the time to make that type of comments, I understand what you're trying to say but this is not the time. Pray that no one is injured or worst!
That's because earthquakes are very unusual for the east coast.
It's not a matter of importance. Earthquakes in California are not unusual; earthquakes on the East Coast are.
No, we just don't get earthquakes like that on the east coast so it is of some note. People get earthquakes in California so often it's not even news. Not because we are more important. You are silly for saying so.
That's because earthquakes are common on the west coast...not so much on the east coast. So when it does happen it's a little shocking.
ps Don't be so naive.
Get over yourself. Granted the Baja quake was stronger, but the Colorado quake this morning was the strongest they've had in 40 years. And a quake of that magnitude next to the nation's capital ... one that's felt up and down the east coast ... is going to get some attention.
And yes, that part of the country IS more important than a city that should be annexed by Mexico anyhow. Get a decent baseball team, why don't you.
Do you think maybe they are more common in CA that it didnt hit the news headlines right away??? Or you think you should just go the cry baby route saying "some people are more important"....thanks for the entertainment!!!
I think it has more to do with the fact that the east coast does not get earthquakes that often. California tends to be rather known for them.
Used to live in Orange Co., CA – big deal here (now in Va), probably wouldn't have woke me up in the old days.
california gets earthquakes all the time. you take that risk by living there so obviously it doesnt make headlines. Virginia has never gotten over a 4.5 so its kind of a big deal. get over it. no ones more important than anythone else. but this is news earthquakes in cali unfortunatly are a way of life.
An earthquake in California is expected and not at all uncommon. Even a larger earthquake. A 5.8 in DC is BIG news. We haven't had a tremor in nearly 100 years!
Its true. Some people are more important. But I think it is more along the lines of California is always getting hit with some earthquake or mysterious fog and the east coast not so much. Look out for Irene people. She's building fast.
That's probably because earthquakes are common in California, whereas they are not common on the east coast. It is therefore intriguing because it is so out of the ordinary. And consequently more people are interested. Unfortunate maybe, but that's just the way it is.
Well at least you know your place in society. Who cares about San Diego, the East Coast runs the US!
Could that possibly be related to the fact that earthquakes are more of a rarity in Virginia than in California?
Because an earthquake here is unheard of just like if California received a foot of snow. You are used to having them we are not!
Transplanted from Santa Monica - it's common for CA to have earthquakes - not common on the East Coast, everyone knows that.
not more important – just much rarer on the east coast – kinda like the news would be if san diego (a town I love) got hit with a blizzard
The west coast gets earthquakes all the time, even you would get sick of it if they reported every one. Get 2 feet of snow and you'll make the news
THANK YOU!!!!
Not more important it just doesnt happen as often
Nah, it's just because it doesn't happen often there. We get them in Cali all the time so it's not breaking news lol.
CA is known for earthquakes. Virginia is not known for this. It has nothing to do with who is more important.
hate to point out the obvious, but an earthquake in CA is not unusual or unexpected. Earthquake in any other part of the US is less likely, and therefore, better news story.
I'm originally from Coronado and currently live just outside of DC. It's not that the people here are more important – it's just that earthquakes don't happen here. A 7.4 happens quite often in Southern California, but on the East Coast a 2.0 is huge. 5.8 has people terrified because they're not used to it. What's news here may not be news there simply because the everyday experience is different.
Yeah, but you guys get an average of 7 per year over 5.0 (according to UC Berkeley Seismic Lab). Meanwhile, the last 5.8 earthquake in VA was in 1897. A little different, methinks.
Yep – West Coast really doesn't matter. The sooner you realize that, the better off we'll be.
You're right. The East coast is way more important than California!!! California will be crumbling into the ocean soon so who cares!!!!!!!!!!!
thats because on the east coast how many earthquakes do we have a year that make the ground shake to vermont from virginia? sandiego you have a earth quake every 5 minutes, so of course cnn wont report it because it happens every so often there.
I remember that. It was actually centered in Mexico.
This has nothing to do with who is more important. The reality is that a 7.2 in Mexico is relatively common. A 5.9 in Virginia is rare, which makes it newsworthy. Complaining that the Virginia quake gets more coverage than a quake in Southern California is like complaining that an airplane crash gets more coverage than a car crash.
7.2 is not NORMAL for California , idiots
everyone is important – but an earthquake in your neck of the woods isn't news. Don't think Washington DC has had an event for many years. We watch the fires and mud slides in real time and try to help when possible. Peace.
Obviously, California gets earthquakes all the time. We rarely experience them on this side of the continent. I would say it's a pretty big deal for us.....maybe not to you.
News, when it hits an unusual area! That's all!
Yeah, that's because San Diego has earth quakes all the time. The east coast never has earth quakes, let alone the entire east coast at once.
We felt it in Newark, DE!
i felt the building vibrate for about ten to fifteen seconds. i first thought that my neighbour is making some noise as i was lying on my bed then realized that this is the whole building vibrating not just my bed....
The Whole conference room shook and our boss said to get out of the building...NYC fashion district
DC really shook, as compared to what you folks in upstate NY and Ontario and South Carolina felt. If you were rattled, imagine what it felt like to us!
def felt it here in Fairfax Va
CNN reports there were no injuries, but my nephew fell off his bike!
my bosses daughter is in louisa just 4 miles from the epicenter....her office building collapsed.......think we will be seeing more pics and reports of damage soon....
Felt it here in Florence SC
Felt it here in Lexington, SC (Red Bank area)
Felt it here in Toronto building wave back and forth for almost 15 seconds, i hope everyone in Virginia is ok.
We felt it hard in Fairfax, I ran out of the store to the street, it was pretty scary.
