According to CNES, an increase in the strength of electromagnet waves before seismic activity from an earthquake, may be able to give prior warning to an occurrence. There are some uncertainties to this theory however. Demeter is a micro-satellite system that will cover almost all of the Earths active seismic areas to test this theory. There will be ground studies to compare the results from the readings. While proven warning signs are not yet in existence, there is work being done in that arena.
under ground animals like rodents, snakes and mole come out of the ground, they will know the earth's seismic waves.answer2 We have4 or5 earthquakes each year, mostly quite minor. I have never felt any pre-cursor effects. I can assure you that cats are of no value in this as they, lying on the bed at night, get plenty of movement anyway and never display alarm.As far as Tsunami are concerned, the answer is different. If you are by the shore and you feel an earthquake, head for the high ground as quick as you can. And warn others as well, but not to the extent that it would compromise your own escape. Another pre-cursor is that of the ocean retreating from the shore. When that happens, you have only a few minutes to escape to higher ground.As recently as1958, in Lituya Bay, Alaska, a tsunami reached over500m high due to 'favourable geography'. And about105000 years ago, an tsunami driven from Lanai in the Hawaiian Islands reached375m as shown by uplifted blocks of coral. [This event could also have been caused by a meteor impact in the Pacific.]usually the people in this field know this, but you can feel a slight movement sensation under your feet
Observe the behavior of animals. It is possible to be warned of an impending earthquake by watching the reactions of such animals as a dog, cat, fish, chipmunk etc. Even ants behave oddly prior to an earthquake. Look for such signs as:
1-Dogs often display erratic behavior such as excessive barking/biting.
2-Pets disappearing suddenly. If your pet goes missing, though you may be worried for your pet, you don't have to worry about an earthquake necessarily. But if many pets in your neighborhood go missing around the same time - this could be a warning.
Studies have shown birds lay less eggs than normal during the interval before an earthquake. Are all of your hens suddenly not laying?
increse the electromagnativity pressure and temperture increase in the interior of earth then sudden vibration that is called earth quick
signs of earthquake 1 start of the shift of the earth with the shocks that can work the building or buildings, 2. characterized by animals that come down from the mountain if the mountain this is the case, for example birds fly, monkey, tiger, wild boar. 3. Heat clouds and accompanied the eruption of the crater the earth. 4. The occurrence of repeated eruptions of Mount 5. if an earthquake happens at sea is characterized by the presence of sea water shrinkage unusual. 6. The occurrence of large waves after the occurrence of shrinkage water swept inland sea and it is usually called by the tsunami
