Can anybody tell me wheather any fore warning system exists for earthquacks?

Answer 1

We have not yet succeeded in developing fore warning system for earthquake. But even though I got the opportunity of forewarning of Tsunami my alert message was ignored.
The quake alarm designed me can be manufactured just for U.S $ 25. Reliability and its affordability was considered by me as most important factors.
Methods for prediction of earthquakes & Tsunami
.
1. Seismic gape: - The earthquake at a particular place may occur for every fixed gape of time. By knowing the past records of the quakes affected at that place may help to decide when the earthquake is next due.

2. Planet position.: - When the stress is accumulated at the tectonic plate boundary and the same time if the position of more than 2 planets comes in a straight line this may help to accelerate the earthquakes. There fore the full moon days and new moon days are more vulnerable days for earthquakes. Some time this method fails why? Think of a sick patient. New moon and full moon days are dangerous for only sick patents. These days will not affect the healthy people. The same way if there is no accumulated stress at the tectonic plate boundaries no need to worry about the planet positions.

3. Sun rays falling method: - If you observe the position of the sun rays falling on our wall at a particular time on all days it should form an angular infinity symbol. If there is any deviation in its path it means that there is some difference in height of the earth. That means some strain noticed at that place. Somebody claims that they can predict the place of epicenter by observing this. The laser beam measuring method of earth height from satellite also will help.

4. MCDB:- Chinese scientist claims that they can predict up to 60 % accuracy by sensing electro magnetic rays.

5. Cloud forming: - Few hours to a few days before the occurrence of earthquakes a cloud reader claims that he has noticed a peculiar mosaic type of formation .We may also notice some lightening in the sky.

6. By sound :- A professor from Ajmeer University claims that he was able to hear a low frequency noise under 125 meter depth in a bore well. The same thing was reported by one Mr. Nair that he heard some roaring noise under the earth one week before the occurrence of earthquake in Gujarat.

7. By frequency of waves :- Mr Richter Allen of Berkley University claims that he can decide the magnitude of earthquake just 4 seconds after observing the frequency of the primary wave. Present method needs the full seismographic picture to find the real magnitude that too from as many places as possible to have fairly accurate results. His claim has got some truth because when there is a slip of bigger tectonic plate the frequency of quake will be less. If a small tectonic plate slips the frequency of the waves will be more.
8. There are several changes in nature and in the behaviors of animals and birds can be observed before an earthquake and Tsunami. I wrote several articles on these subjects.

Answer 2

There had been various systems put in place with more than dubious results. I will answer both for warning and prediction system although this is not exactly the same.
A warning system must give you the location, the time, the strength and the probability of the earthquake. Usually, it is possible to have a good idea of the location, a fuzzy idea of the strength and a very vague idea of the time. Giving at the end a low probability of occurence for a given time.
The chineses used a serie of warning from animals, water well level dropping suddenly etc... in the 70s' and succeeded to evacuate a town KNOWING ALREADY THERE WAS A HIGH RISK OF EARTH QUAKE. They saved many live. But one year later, they fail to see the same warning and it was the worst earth quake ever (250 000 deaths).
The greeks invented in the 90's a method, the VAN method based on the fact that rock under high constraints and about to release this constraint are developing a small electric signal prior to the earth quake. This electric signal in turn creates a small electromagnetic perturbation which is measurable. It gave some interesting results but very difficult to interpret. I was undirectly involved in some of this studies and for example, a train using electricty less than 4 km or a welding point less than 1 km from the measuring point are making perturbations.

Answer 3

They are working on it. Geologists are studying, and tracking them. They have said in an article I read a few years ago, that the fault lines seem to "talk" to each other. Earthquakes can happen anywhere, even in New York (hasn't there for a really long time, but it has), yet the Pacific Ocean area is the "Ring of Fire" for earthquakes. The Asian countries, Alaska, and all along the West Coast is the "prime" area for quakes to occur. The scientists can look at the previous quakes, including clear back into the early days of our country, like the 1800's and see what the pattern then has been like. Quakes, depending on how strong they are, as you probably well knw, have been felt as far as the Nevada area, when hitting California, etc. One night a few years back, I was having a candle party in my apt., and a quake hit a part of Canada, that the effects were felt clear down to my place in the states. NW states. A few things in my apt. shook for a few seconds. Earthquakes are not fun to go thru, you just have to ride them thru, and pray to do okay. Take care.

Answer 4

Earthquakes are a mayor worry in Mexico City as we suffered an 8.1 earthquake 20 years ago that killed some 400 000 people (unofficial, but real data) The most of them comes from the pacific coast, so goverment did install, several years ago, a seismic alarm: if an earthquake takes place in Acapulco bay, an alert radiosignal is going to be shot giving to people in Mexico City 1 minute to evacuate buildings and look for shelter, in order to prevent dissaster again.

Answer 5

There is no official warning system for earthquakes. Animals seem to have a sense that something isn't right. Seismic monitors may pick up a slight increase in activity before a quake, but quakes are so unpredictable. You just have to be prepared.

Answer 6

Earthquack ? Best ask a duck.

Answer 7

Last I heard they had been able to predict about 10 minutes in advance however this was in the mid nineties and I am not a geologist so I have no idea of advancements, technology, ect.

Answer 8

If you notice any animals in the area acting rather erratic, run for cover. They always seem to know when something's about to happen, from tornadoes to earthquakes.

Answer 9

as far as i know, a seismograph records where vibrations are occurring, and they are monitored fairly constantly in areas like san francisco, the san andreas fault, etc. but i don't know how much advanced warning there is.

Answer 10

Earthquacks ... I know it was a typo, but it's still cute :o)
