Anonymous Coward User ID: 822802 United States 08/24/2011 12:30 PM Report Abusive Post Report Copyright Violation | Doesn't the east coast work differently than the west coast? If a quake happens on the west coast it's only fault along that fault line but seeing as how there are none over here on the east if an earthquake happens everyone feels it. Am I the only Virginia resident who remembers the earthquake 7 or 8 years ago???? |

Anonymous Coward (OP) User ID: 1107716 United States 08/24/2011 03:02 PM Report Abusive Post Report Copyright Violation | My question is how they figured out it was centered there and a 5.8 quake...Do they have sensors all over the USA or is this a guesstimate using other sensors... Quoting: ????? 536288 Every state that felt it picked it up as an EQ. Main registered it as a 5.2. PA a 5.3. I am in NY and it shook items off of shelves, and lasted around 30 - 50 seconds. VA picked it up the strongest so the software assumed the epicenter was there. So, if every state picked at a 5.0+, it was the entire eastern seaboard. That explains why it was registered at Mt. Rainer (2800 miles away) which showed it lasting around 18min. Yellowstone (1600 miles away) showed it lasting 33min. It had to be the entire east coast. No some little local 5.8 in VA. |

Your science is off. If the granite runs from ME to VA, then there you go, the entire Eastern seaboard. That entire plate slide yesterday for a half hour. Look, 5.8 EQs happen every day, all over the world and they aren't registered as a 5.anything 1200 miles away I dont care what kind of soil, granite or plate they are on. |

Anonymous Coward (OP) User ID: 1107716 United States 08/24/2011 03:32 PM Report Abusive Post Report Copyright Violation | When earthquakes hit areas like the east coast, they energy released travels a longer distance due to the plate structure. Areas that are closer to major fault lines will dissipate faster due to the faults. They are absorbed quickly, where as this one reverberated up the coast a very long distance due to the less fractured plate. Quoting: Zlyle14 The question is, was it natural or man made? We have many quakes on the East coast, I don't feel any of them. We had three 3.0 last year 40 miles from me, I didn't feel anything. We had a 6.0 in Canada 170 miles from me last year, I felt nothing, now I am supposed to believe that a 5.8 in VA traveled 700 miles and gave me a 5.2? Aint happenin. Also, lasting 33 min.??, that ain't your typical "5.8". In fact, a 33min. EQ should be a 20.0 or something. 5.8s only last up to one (1) minute max. |

Quoting: sapphiressmile nli 1516914 I felt it in Eastern KY cracks = no picks = well, I could go out to my work shop and show you some items knocked off my shelf. The Washington Monument is listing, and a bunch or buildings in DC are supposedly busted up. In this case, damage doesn't matter. What is going on does. |
Anonymous Coward User ID: 967845 Germany 08/24/2011 03:39 PM Report Abusive Post Report Copyright Violation | Q = Since when is a 5.9 picked up on seismographs all over the country and even outside the country? Quoting: Anonymous Coward 1107716 A = Never Q = Since when is a 5.9 Felt in up to 20 states? A = Never. Not even a 9.0 is felt in that many states. Q = Since when does a 5.9 last 33 minutes long? A = Never This was not a 5.9 EQ in Virginia. It was picked up the strongest there so that is where the software placed it. It looks to me the entire East coast moved, and probably upward. From Canada to Georgia. This means that yes, the West coast will probably move downward. Pay attention to this. If this is true there will be more misleading and more EQs. Switch your natural gas lines over from solid to flex like (PLEX lines). Secure your important items in your work shop, desk, and food storage shelves. Convert glass jars from glass to plastic, etc. Below are links to one of Yellostone's 20 or so seismograph stations. Its shows it was INTENSE and lasted 33 min. YELLOWSTONE [link to quake.utah.edu] Mt. Rainer - Thousands of miles away - [link to www.pnsn.org] The ground and rocks on the east coast is different from other places. Earthquakes travel farther. Learn about attenuation. Feb 21st 1774 - 4.5 EQ in Petersburg, VA, was felt in Winston-Salem, NC over 200 miles away. Aug 27th 1833 - 4.5 EQ in Central, VA, was felt in the District of Columbia, Maryland, and North Carolina. Apr 29th 1852 - 4.9 EQ in Wytheville, VA, was felt in the District of Columbia, Maryland, New York, Ohio, and Pennsylvania. THIS IS THE BEST REFERENCE HERE May 31st 1897 - 5.8 EQ in Giles, VA, was felt from Georgia to Pennsylvania and from the Atlantic Coast westward to Indiana and Kentucky. K OP, what do you have to say now? |

No, we really don't have many quakes on the east coast, and you can look that up on just about any seismology website, including those stationed in Virginia. We are nowhere near a major active fault. New Madrid has only recently been making an appearance, and VA is still hundreds, if not thousands of miles from the fault. Minor faults run along the Appalachians but have been dormant, for the most part, for millions of years. Just by saying there was a 6.0 in Canada, doesn't mean it was the same type of quake that happened in VA. It could have been a shorter quake but still high on magnitude where as the VA one was about 30seconds long here(about 30 miles north of the epicenter) and reverberated along the plate to the north. There were also multiple(3-4?+) aftershocks and probably tons of tiny ones that continued to rattle the area, which caused the entire plate to ring like a giant bell.

The degree to which someone feels an earthquake does not just depend on magnitude - but also depth. The other quakes you mentioned that you didn't feel might be if they were at a greater depth. A shallow quake will be felt over a much greater distance. |

Generally speaking, one would assume that a lengthier (time) EQ would equate to a larger magnitude, but that's not true. Also, this didn't register as a 5.9 across the entirety of the east coast. In SC, we registered between a 2.5 and a 3.0 -- get some facts straight! |
