In regards to a seismograph’s location, does the p-s interval get larger or smaller with the increasing distance from the epicenter?
a. epicenter – the surface location of an earthquake
b. fault – a fracture in the crust along which movement has occurred
c. hypocenter – the underground point of origin of a quake
d. tsunami – an underwater earthquake
A) The epicenter is calculated after the all the aftershocks of an earthquake are plotted. It is the statistical center of the earthquake. The focus is the spot of first motion of the rocks.
B) The epicenter is where the energy is first released and the focus of the earthquake is where most of the damage is done
C) The focus of the earthquake is were surface waves are first detected while the epicenter is where the P and S waves are detected.
D) The epicenter is the spot on the Earth’s surface directly above the focus.
I’ve been warned that an earthquake of 7.2 magnitude will hit where I live. The epicenter is a bit far but what if you live on the fault line? Will it be very strong? What happens if there are high-rise buildings on top of a fault line but not directly on the epicenter? Will it fall/topple down? My parents work in high-rise buildings near the fault line. I’m really scared. Thanks 
well i bought an epicenter at a yard sale and the remote doesnt have the correct cable so where can i get one and what is the cable called? the cable looks like a a phone cable but those dont work..
I only know that Richter scale 3 will shake 0.1 mm at a distance of 100 kilometer. It increases by ten fold for each Richter scale magnitude. Give example how it will vary according the distance of epicenter. They say it is Inverse Square of the distance. Please explain with a model calculation. If an earthquake is measured from a distance of 2000 kilometers from epicenter and if the magnitude is 9 in Richter scale what will be the maximum shaking. Will the S wave pass through sea water.?
in my literature class, we are making this big map of Hiroshima and where the the people are from the epicenter of the bomb. We need to know the exact location in order to put it on the map..i dont mean the exact location but the area…so???
My family and friends have been hit hard because of the 2010 baja california earthquake. The magnitude was greater than the Haiti earthquake. Although the death toll doesnt compare at all, the damage done is unbelievable. Most of my family members live in Ejido Oaxaca, Mexico, which was right next to the Epicenter. I want to setup a website so people can donate money which can be helpful for Food and water. We have had a couple of phone calls to them and they said that the gallon of water has sky rocketed in the local markets to 60 pesos which is about 6 dollars. People dont have this kind of money so they need our help…
so far i have created this blog.

but now how do i make it so that people can see it and make a donation?..
i know how to find the time and all but i dont know how to use the earth science reference table for the epicenter
for example if the time is 1:40 seconds what is the distance from the epicenter.
can you please explain the steps? thanks

i need help on this hm question is it true or false and if its false i need to now why.
here it is:
an earthquakes epicenter is located deep underground
(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.http://www.cnn.com/2010/US/02/10/illinois.earthquake/index.html?section=cnn_latest
What is the difference between the epicenter and the focus of an eathquake?
I am doing a project fo science. I have to find 10 recent earthquakes with a magnitude greater than5.0 on the Richter scale. Then I have to compile my fidings in a table that includes the epicenter and the magnitude of the quake, the damage it caused, and any other interesting information about the quake. Please help me find earthquakes and a place to make a table.
I just need help with mistakes and the like.
My phobia, the thing that terrifies me the most, is earthquakes. The millions of people that live in California, let alone on the West Coast, fearing earthquakes may not seem so irrational. Earthquakes have happened. Earthquakes have killed. Earthquakes will happen. So why the use of the word “phobia” if my fears have valid reasons behind them? It is not whether or not my fears are sound or not, but rather my reaction to the earthquakes. All my problems started with one event, problems the likes of which still plague me to this day.
In 1994, an earthquake rocked most of Southern California. The earthquake and the damage it caused could be felt for miles from the epicenter in the San Fernando Valley, and clocked in at a whopping 6.7 on the Richter scale. I was only three at the time, but I can still remember that day vividly. I woke up to my uncle, who had been staying with us at the time, yelling at me. My bed was halfway across the room from where it had been when I had fallen asleep. My parents got to me just seconds after my uncle with my mom screaming for me and running after my dad. It was chaos as we tried to get out of the house. Glasses, plates, pictures, all seeming to fall on to of us, falling from their respective shelves and shattering on the floor. It was no wonder that no one had noticed my dad’s foot had started bleeding profusely until we were safely outside. For weeks after that day, I had nightmares and would often und up in my parents’ bed.
Nightmares weren’t the only thing that has resolved from that night. Since then, anytime there have been earthquakes or aftershocks or anything that even feels like an earthquake, I freak out. Immediately, I start to feel weak and shaky. I become fidgety for the rest of the day, and there is nothing I can do to calm down. There is nothing else that can terrify me so, and, in fact, as the years go by, it seems as though my fears have increased rather than be assuaged by time. The interesting thing about my reaction is the fact that I only seem to get these “symptoms,” for lack of a better word, when the earthquakes occur and after the entire ordeal. In between, in every other crisis or danger I have faced, I remain calm, cool, and collected. Only in the face of an earthquake do I freak out.
Most people get over their fears when they exist because of natural disasters. The people may still have an aversion to the things that remind them of the event that they have lived through, however, they tend to become used to the dangers that go with living in the region. And then there’s me. I still have my fear of any and all earthquakes, no matter how small. My sister accidentally bumping my bed while in my room for some reasons or my dogs jumping on my bed have me waking up, already on high alert. Every time I get worked up, I assure myself that everything is fine, that I am overreacting, and that I won’t act in such a manner the next time. Every time I get worked up, I forget the promise I made last time. In fact, over time, my fear seems to increase despite my effort to rein it in just slightly. Albeit, this has occurred over many years, and only slightly at that. While many other phobias interfere with people’s lives, mine has yet to do so. As such, I have little reason to for fully getting over my fear. Yes, I flip out when I believe there to be earthquakes, but it only occurs every so often, and I have yet to be incapacitated by it. I have only really freaked out at home, anyways. Nothing too embarrassing … yet.
Regardless of whether or not I have been embarrassed by my fear, the fact of the matter remains. An earthquake in 1994 scared me so thoroughly that I can still feel its repercussions, but not so much so that I have felt the need to get professional help. Perhaps, one day, in the near future, preferably before the next earthquake takes place, I will move to someplace else (Europe, maybe) where another phobia will replace my current fear of earthquakes.
I was reminded of it when my brother – who resides near the epicenter -sent me an e-mail yesterday. The ironic thing is it was also his birthday. Here’s the response I sent to him:
I’ll never forget that night. Mom, Dad and maybe Sis were at the auction house across from farmers market, and I was home ready to watch the Athletics play the Giants in the World Series.
I had the TV on and was immediately noticed quite a lot of commercials on ABC. But I dismissed it as the necessary evil that surrounds sports what with the abundance of promotions and advertising dollars coming in from every source they can find.
Anyway, a short-lasting signal came up from Candlestick Park and I remember Al Michaels stating that the game had been postponed because of a major earthquake. I later realized that your area could have been affected and immediately tried to call you on the kitchen phone. The first attempt resulted in a busy signal. I tried again and I believe that was the one where you were in your driveway and you told me that you felt like you were on a see-saw because your car would go up and down as you were too. Then the signal got disconnected.
I’m not sure if we ever had a chance to get connected again, or if you and I got to talk later. I saw the lights of whatever vehicle that Mom and Dad were in, and was standing at the back door holding the screen door open. When they got to the steps, I said "Hey, first off, (My Brother) and (His Wife) are okay – I’ve spoken to them. But their area was just hit by a major earthquake. The calls keep getting interupted because of the aftershocks., but they are okay and are standing outside their house and there’s no major damage to their immediate area."
After that, I recall Mom getting you on the phone while I was in the living room watching all the coverage of the disaster. And honest to God, I knew the moment I first saw the Nimitz Freeway in Oakland that it had collapsed and I was almost certain that people were on the lower deck when it pancaked.
I’m glad you were okay. I was really worried about you.
Did you feel it ? What where you doing ? Where were you ?
I live about 5 miles from the Epicenter. It was pretty big from where I was from. I heard that this MAY be a pre-shock from the bigger earthquake that will eventually hit California. But they said there was a bigger chance of the bigger one happening as a 30% chance withing 24 hours. But now the chances are slimming to 1% since it didn’t happen. Hopefully it doesn’t :/
Also when it was happening all I was thinking if ..
it was going to be the "BIG one" I was freaking out. Just like the whole shake. Nothing was damaged at my house though. Just a candle flew off the armore.
I need to draw a map for science class with the epicenter on it. PLEASE don’t tell me it’s near Canete because I don’t know where that is in Chile so I can’t put it on my map. You can also attach a picture of a map with the epicenter on it. Thanks so much!!
How far will the tremors be felt from the epicenter. I happen to reside in Tucson by the way.
Why does the greatest shaking of the ground occur near an earthquakes epicenter?
I realize that an earthquake just hit california. I’m hearing that it was just a foreshock, and i’m wondering if there really is a chance of a even bigger earthquake coming in the next few hours. If anyone has any information, can you tell me what are the chances, is where, because i live in a city right next to the epicenter in Chino hills
At Epicenter 09, on August 22, they do not say on their website what the order/ times are that the bands are playing. The event is 12 hours, and i would like to know so that I can figure out how to schedule going, without staying the entire time. The band i am most interested in finding out what time they are playing at is Tool.
I also had a similar one 2 months prior to the Northridge quake. I wrote a letter to the Times, and they later mentioned it in an article about psychic tools of predicting earthquakes.
This recent dream was much more devastating, and I’ve again sent a detailed letter, (Registered), to the Mayor’s Office.
The 4 page missive and a copy of the Times article and letter (Northridge) will be sold on eBay Thanksgiving Day, with full proceeds to be given to the Red Cross, Los Angeles Chapter.
Those living in or near the Riverside epicenter should go to Las Vegas before it hits.
It eclipses all US quakes ever recorded.

How could someone predict the approximate location of an epicenter without a seismograph??
How far will the tremors be felt from the epicenter. I happen to reside in Tucson by the way.
The epicenter was in Canada and the aftershock was felt throughout N.E. P.A. It was in the late 70′s or early 80′s, and I am looking for the year, but would like to know the date.
It occured in the evening, and I believe it was late summer.
I want to get a bass knob to add more bass to songs or to have control over the bass but the epicenter cost 160 bucks while the soundstream cost like 60 dollars. Before i buy any of these i want to know what the difference is though? I like really loud bass so please help me
Why does the difference in arrival times of the p-wave & the s-wave become greater as you get farther from epicenter?
After an earthquake, you are given seismograph reading from three locations, where the coordinate units are miles
At A(2, 1), the epicenter is 5 miles away
At B(-2, -2), the epicenter is 6 miles away.
At C(-6, 4), the epicenter is 4 miles away.
a) What are the coordinates of the epicenter?
Why destruction caused by an earthquake greater at the epicenter than other locations?
