I know, it’s late to ask this question, but for those of us in the LA area, did you feel it? what did you experience? I talked to so many friends who swear they didn’t even know what was going on! they felt absolutely nothing! I live in the San Fernando valley and only noticed the water in my pool undulating back and forth before I realized it may have been a quake. I was having a bbq with family and friends and they were saying I was crazy for even thinking that! But you already know what happened…

I’ve read that doesn’t happen, but we were watching the news and saw that now Japan had a large quake. I studied that little earthquakes happen around us all the time, but the large ones are not as common. Could the recent large quakes be triggering the ones like Japan just had?

Here is a quote from an article regarding the quake in Italy (L’Aquilla).

"The U.S. Geological Survey said the big quake was magnitude 6.3, but Italy’s National Institute of Geophysics put it at 5.8 and more than a dozen aftershocks followed."

I know that the Richter scale is logarithmic, so this difference is actually substantial. Do estimates normally vary this much?
Are you saying that it is different because one measurement was made on the N. American plate and the other made on the European plate?

I live in Missouri pretty much right on this fault line. I was wondering if you know about any new predictions regarding this fault line. Is a quake way over due? Do they have an estimated time on when we should get a quake? Where can I go to find this information? Thank you.

A few days after the big quake in Chile, people are starting to loot. They have not eaten for days. Banks are closed and couldn’t operate even if they were open, so there is no money available to buy things. If people are starving, is it permitted to just take the things you need to survive? Does the law allow that, or are you just supposed to go off and die? Is there any provision in the law for allowing people to do what they must to survive a disaster, or are we required to meekly starve to death?

Please explain.

Include:the mechanics of quake creation within the tectonics system – thus you would discuss seafloor spreading, plate subduction, faulting, magma movement and bedrock.

A recent post on a global-warming website specifically aimed at youngsters implicitly blames man-made global warming for the Haiti earthquake.

In an article titled – with breathtaking insensitivity – ""What the Haiti Quake Means for the Climate Movement"" (because that’s the main concern here, right?) it says "as the planet heats up, disasters are becoming more frequent and severe" and that Haiti is just the latest example of this.

Although it hedges by stating that ""it is inherently difficult to map changes in the Earth’s climate to any specific event"", it leaves the young reader in no doubt as to the underlying cause, saying ""every time a natural disaster hits, I think about fossil fuels"" and that ""what we know is that burning fossil fuels is altering the climate, increasing the likelihood that disasters like this one will occur.""

It’s only a short article. Have a read and see what you think. Lowest of the low? Are there *any* depths to which they won’t stoop?

If this is true that Puente hills fault is supposed to make a 7.3 Landers Size quake from the San Gabriel Valley to Downtown LA. How come this isn’t well known in the US Mainstream Media like Hayward, New Madrid, San Andreas, Denali, Alaska Subduction, Denali, and the Cascadia are. Besides that LA and the rest of CA have so many Earthquake faults to investigate with.

(CNN) — An early morning earthquake rattled northern Illinois on Wednesday, shaking an area about 50 miles west-northwest of downtown Chicago, the U.S. Geological Survey said.

The quake was originally reported as having a magnitude of 4.3, but the USGS later downgraded it to magnitude 3.8. It hit just before 4 a.m. CT (5 a.m. ET), with an epicenter about 3 miles underground. The USGS pinpointed the quake between the towns of Virgil and Sycamore, Illinois.https://www.cnn.com/2010/US/02/10/illinois.earthquake/index.html?section=cnn_latest

well, im 15, and recently undergoing a change of lifestyle.
basically im trying to make myself a better person.
anyway, lately the only thing ive been really thinking about is death and natural disasters.

today wasnt a major quake for my city, atleast in my house it was as if 10 heavy truckes rolled by.
anyway, we’re somewhat close to L.A and would like to know how bad earthquakes would affect us?

all i can do now, is pray.
