I am looking specifically for maps that illustrate the the extent of faulting (the area of the fault on which slip occurred) for the following historical Earth quakes:
1.1906 San Francisco earthquake
2. The 1857 Fort Tejon earthquake
3. The 1989 Loma Prieta earthquake
4. The 1992 Landers earthquake
5. The 1994 Northridge earthquake
THANKS!
I would like to find a publication with maps of these three types of events with information on each event, such as date, size, location, effects, etc…
It would mainly be about significant events that have been proven or documented.
My boss has asked me to research the effects of having small earthquakes back to back. Any ideas of what this means or what it ‘could’ mean? Please dont send me links to pages of maps of CA with the earthquakes and their magnitude ect. Ive got all of that info.
Please answer with a link where you found the info.
Thanks so very much!
please help me how can make it. Any major 5 diversity. Give me pictures and maps also. Give report on man’s interference, how it results in soil erosion droughts, faulty constructions on hills, landslides, Conclusions, Impact during cyclones and earthquakes.
Don’t forget to put your name in the answer. I’ll be putting it in the References and Sources Column.
Thank You.
I live in Washington state, and receive notifications from the USGS about earthquakes in the Pacific Northwest area. There have been a series of quakes off the Oregon coast over the past 10 days or so – the largest was a 5.2. I’m not a geologist by any stretch of the imagination, but I was watching the news last night, and a short piece on the quakes mentioned that this kind of series of quakes is usually associated with volcanic eruptions. Of course, right now, there IS no volcano in that region; is it possible that we’re about to see a new one begin? I’d be curious to know what people educated in this sort of science think – thanks!
Btw – I’m not "worried" about it or anything; I’m just wondering if it’s POSSIBLE. I certainly think it would be fascinating to see if it occurs, but I have no idea if that’s possible. I do remember MANY years ago (I’m 53) the process of a volcano (in the Atlantic, I think) turning into an island; it was documented in something like Life or National Geographic, but I was much too young at the time to do much more than look at the pictures.

Ok – yeah, I know about the Cascade volcanoes, of course (I can look out my window and see Rainier, after all…). I guess it’s just that the USGS folks are saying there’s no volcano in the immediate area of the quakes, so I’m wondering if it’s reasonable at all to think that another one MIGHT form. Of course, I know it would take an EXTREMELY long time to form to the size of a Rainier or a St. Helens, but *could* this be the start of a new one?
Has anyone been following up on it lately? There has been about a good 100 to 200 or so, most small. Here’s a list:

Its in a geothermal area near a dormant volcano. Its getting annoying aside from nerve racking trying to sleep at night.
Here’s a recent report of earthquakes, man they just keep coming,gah, I hope its just easing pressure off of San Andreas.

Ok so can anybody give me some information on earthquakes? I’m studying abroad this year in Italy around 40 miles from where the big earthquake was the other day. Anyway what I’m wondering is if anybody knows if it’s normal that keep having big shakes. Some are being classes as aftershocks obviously but we’ve had 3 more above 5.0 on the Richter scale, with the last being only around 20mins ago. Is this normal? And if so and it is just the settling of the ground how long can we expect major shakes for? I’m really scared! these apartment blocks swaying like they are all the time is really frightening, I can’t sleep and I live on the 5th floor so it feels really dangerous up here. I’ve just found out that the last quake measured 5.7 on the Richter scale and like i say this was only a short while ago, what can I do to make myself feel better?!
If you want to look at these links you may be able to tell me more about if it’s really abnormal or not, I know the news here has been calling the situation an anomaly?
If it helps this link shows all the recent quakes apart from the last

and this shows the biggest ones, including the last one

Thanks the geologist that’s helpful. Well as I live on the 5th floor I’m not thinking about exit strategies because I heard you shouldn’t go into the internal stairwell. This may sound stupid but I thought I may put a mattress on top of my bathtub with a couple of bottles of water etc inside then if I feel another one get in under the mattress. Is this a really stupid idea or not?
From the Time’s Magazine | Katrina: One Year Later
Floods, Tornadoes, Hurricanes, Wildfires, Earthquakes … Why We Don’t Prepare
"Every July the country’s leading disaster scientists and emergency planners gather in Boulder, CO, for an invitation-only workshop. 440 people obsessed with the tragic and the safe, people who get excited about earthquake "shake maps" and righteous about flood insurance. It’s a spirited but wonky crowd that is growing more melancholy every year. After 9/11, the people at the Boulder conference decried the nation’s myopic focus on terrorism. They lamented the decline of the Federal Emergency Management Agency (FEMA). And they warned to the point of cliché that a major hurricane would destroy New Orleans. It was a convention of prophets without any disciples…"
"The real challenge in the U.S. today is not predicting catastrophes. That we can do. The challenge that apparently lies beyond our grasp is to prepare for them." (Times Mag. Aug 20th to read more)

my house shook for like 30 seconds to a min.

is that list trying to say that California is Getting Hit Alot Today from Earthquakes
Knowing that large dams have and can cause earthquakes.does it sound reasonable to make the connection
between the recent quakes,and the stress that the dam and
resiviour are placing on the crust?
Maybe the stress transfered to a weaker fault line and ruptured it.It also could be a contributing factor in the strength
and high number of aftershocks.
I would like to hear good solid answers to this question.I am
researching trying to find maps of tectonic plates,and asian
earthquake faults.
Is this source some kind of left-wing propaganda?

Alaska has many earthquakes, as does all the west coast of the US. but it seems the earthquakes stop at the borders of Canada.

Looks like far more than a normal day….what do you make f it?
I have found maps of the recent earthquakes there, but not an actual Fault Line map.
THANKS!!
the one you can google that came from Haiti and jumped Costa Rica , you can also see it on USGS earthquakes maps.
hybrid map
if one would look one could see that it is different.
Hey yesterday in Japan there was an earthquake and then some aftershocks in the afternoon.
Later that night I (In Hokkaido) felt an earthquake later that night, did anyone else living in Japan feel an earthquake last night? I was surprised that I would feel it all the way up here in Hokkaido. I text my friends and they all felt it too.
yeah I found out there was one just off from where I live

coolies!

Also L.A. got hit 4.1 quake today and 4.7 at sunday, not far from there is also a oil drill, you think oil is the cause?
California/Nevada in the past week alone. Now granted most of these were level 1 and 2, with an occasional 3 tossed in for good measure. My question is…were they all really EQs? how sensative are the monitors–would they give a false read for say, a building demolition? Please don't flame me. I went to the local science museum last week and they had a really interesting display– enough to catch my interest and do some web surfing…
http://earthquake.usgs.gov/eqcenter/recenteqsus/Maps/US10/32.42.-125.-115.php
I can't find any maps on this subject and I am just wandering where exactly they are. If you could give me a cite where I can look at a map I would greatly appreciate it. Also can you tell me how long the fault line has actually existed? Please no answers saying "millions" of years old.
