We had an earthquake with a magnitude of 4.5 on the Richter scale this morning. As far as I remember this is the first one I haven't overslept . It was an interesting feeling. By far not so emotional like a total solar eclipse, but interesting. During the earthquake I have heard a low frequency tone. Imagination? Or could the tone be created by the oscillation of the building and it interiors or was it caused by the earth itself? Regards Gyro
no clue. where do you live? i've been in many quakes. i find them to be fun.. as long as no one gets hurt, of course!! i look at this daily, several times a day. http://quake.usgs.gov/recenteqs/
Unless it was somehow created by very near-surface brittle deformation (a high crustal fault), then it was either (a) you developing tinnitus, or (b) something at the surface. None of the 4 major types of earthquake waves has a frequency high enough to be perceived by the human ear (i.e. <20 Hz), although apparently infrasonic waves can cause anxiety, and the false perceptions*. *http://skepdic.com/infrasound.html.
Funny what you said about sleeping through them. I used to sleep through them all the time when i lived in california. LOL
4.5 ... yeah that would probably give the hum that's what I thought first one I went through in san diego... sounded like a speaker was sort of humming kick it up a notch or two.. then it's shit falling down
Hi, I live in the southwestern part of Germany. This area isn't known to be a major earthquake area. But we have a few over the year. Usually nobody gets hurts. Regards Gyro
Hi, damn, and I have thought the noise I hear regurlarly is just the wind in the trees. OK, no fun. A friend of mine suffers from a form of tinnitus. He likes to spend hours in the server room because the noise floor there blends out the ringing in his ear. Regards Gyro
Hi, often the shaking lasts only for a few seconds. If you are fast at sleep the show is over before you even realise that the shaking is not part of your fancy dreams . Regards Gyro
thier was recently a earth quake in my home country which is founded in central america (honduras). and am wondering is that normal? their isnt any plates it stands on??? nor volcanos!! I knoe theirs one south in Costa Rica but still too far away.
Do a search. Honduras is on the Caribbean plate and just north of it, coincidentally, is the North American plate where the epicenter of the earthquake you are talking about happened. The epicenter of that quake was right on the plate boundaries to the north of your country located in the Caribbean sea. That same quake also caused damage in Belize which is on the North American plate. The boundary you are thinking of to the south, by Costa Rico, is where the Caribbean plate and the Panama plate boundary is.
lately i've heard of many in europe lately... my cousin phoned me a couple of months ago telling me there was one where he was (i'm not sure if he was in spain or stuttgart though )
Hi, if there is an earthquake in Italy that is noticeable (without seismographs) in Stuttgart, well, then there might be no Italy anymore . Regards Gyro
JUST north of Italy?? Umm, ever heard of Switzerland. And yes there was an earthquake in Italy back in April, a 6.3, but it was in the middle of the country, in Aquila. That is a LONG ASS way from Stuttgart.
Earthquake hypocenters/epicenters are calculated by using data from 3+ seismographs, which are incredibly sensitive instruments. The event in L'Aquila would have been picked up by seismographs across the world. Es ist wahrscheinlich, dass ein Seismograf in Stuttgart die Erdebenwelle entdecken würde.
