Astronomical tide of concern may lead to the earthquake (Figure).

<P Align=center> Keywords: Seismic wave astronomical astronomical astronomical phenomena external sun moon earth </ P> <P align=center> </ P> <P> the date of the earthquake just occurred in the Quarter (the lunar eighth day) .. .That day, the winding time in 11:47. .Winding, the sun, Earth and Moon are arranged in a right triangle; from the earth, the angle of the sun and the moon is just equal to 90 degrees, winding this day, there are from two different directions of the tidal force influence on the Earth. .Some major earthquakes in history occurred before and after the winding or last quarter: If the magnitude 9.1 Alaska earthquake in March 9, 1957 (eighth day of lunar month), this day happens to be winding; of magnitude 8.8 .South America, Ecuador earthquake, occurred in January 31, 1906 (seventh day the first lunar month), the next day for the winding; Richter magnitude 8 earthquake in China Gansu Gulang, appears in the May 23, 1927 (lunar .Niansan), the next day for the last quarter; in the country's 7.3 magnitude earthquake in Haicheng County, Liaoning Province, appears in the February 4, 1975 (Lunar New Year round-December), last quarter to February 3. .World Scientific reports </ P> <P> Sun Moon Earth in the same plane moment of the earthquake occurs in the sun, moon, earth three objects in the same plane. .In normal times, the moon and the sun, the earth is not in the same plane running, but more than a 5 degree angle. .When the three objects in the same plane, may be of some plates on the Earth's crust have a special impact or resonance. .</ P> <P> the moon and the sun in the same latitude on the eve of the earthquake, the moon and the sun is located on the same latitude. .May 11, the sun in the sky, 18 degrees north latitude, while the moon is passing from north to south, 18 degrees north latitude. .In other words, May 11 For a moment, the sun and the moon at the same latitude (latitude 18 degrees) on the. .Sun and Moon in the sky for two days the body on the same latitude, such efforts could play lead role in the earth quake. .World Scientific reports </ P> <P> the location and intensity of earthquakes mainly from the Earth's interior, but the time may be affected by the earthquake objects outside the Earth's tidal force and the external effects of radiation and magnetic fields. .When the sun, the moon and the earth in space, in a special position of arrangement, the Moon and Sun on the Earth's forces there will be a critical point or turning point, it is possible to trigger earthquakes, which is external astronomy earthquake. .</ P> <P> high astronomical tides is worth noting that the two World Scientific reports </ P> <P> According to the Guangdong Astronomical Society said that this year early in June, there are two strong parties should pay attention to astronomical tides. .One in at 9:00 p.m. on June 3, when the moon from Earth recently, only 357,251 km, which is November 24, 2007 Moon and the Earth since the time away from the nearest; the other is at 3:23 on June 4 .Sun, Moon and Earth are arranged in a straight line (Moon). .If these two high astronomical tides longer time interval, it would only isolate belonging to the general astronomical phenomenon, but only 6 hours away from Talia, will form a strong astronomical tides superimposed, it is possible wave of gases on the Earth ( .Atmospheric tide), liquid tide (ocean wave) and tidal (tidal crust) have a significant impact. .At present, the Richter magnitude 8 Wenchuan earthquake, there is dislocation of crustal plates, as well as aftershock energy release is not complete and other factors exist. .Therefore, the June 4, the two high astronomical tides after another, workers and relevant departments should be concerned about earthquakes. .</ P> </ p>.
