M7.8 Earthquake in Central China

2008 May 11
by Dave Schumaker

A magnitude 7.8 earthquake struck central China earlier today. It was centered in the Sichuan province, about 1500 kilometers from Beijing. Shaking was felt as far away as Beijing. CNN reports that at least 10,000 people are feared dead. The earthquake was rather shallow (the focus being located only 10km beneath the surface).

The following is a release by the United States Geological Survey, National Earthquake Information Center: An earthquake occurred 90 km (55 miles) WNW of Chengdu, Sichuan, China and 1545 km (960 miles) SW of BEIJING, Beijing, China at 12:28 AM MDT, May 12, 2008 (2:28 PM local time in China). The magnitude and location may be revised when additional data and further analysis results are available. There have been no reports of damage.

From CNN:

At least six more earthquakes — measuring between 4.0 and 6.0 magnitudes — happened nearby over the three hours after the initial quake at at 2:28 p.m. local time (0728 GMT), the USGS reported.

A spokesman for the Beijing Olympic Committee said no Olympic venues were affected by the earthquake. The massive Three Gorges Dam — roughly 600 km east of the epicenter — was not damaged, a spokesman said.

The earthquake was also felt in Hong Kong, Shanghai, Taiwan, and as far away as Hanoi, Vietnam, and Bangkok, Thailand, according to the Hong Kong-based Mandarin-language channel Phoenix TV.

Update: The latest estimates say that over 10,000 have been killed. And it will probably be significantly higher than that as rescuers reach cities that have been cut off due to damages to roads and lines of communication. From CNN: It reported that authorities were yet to reach Wenchuan County — which sits at the epicenter of the 7.9-magnitude earthquake with a population of about 112,000 — because of damage to roads.

    How could the water which seeped inside produce an earthquake?

    Earthquake is caused due to the movement of the land is a myth. The most important thing that is missing in this view is that there is no explanation for why earthquake occurs in the centre of the land instead of the peripheral area.
    Actually the land is rising in different places. This is the reason why earthquakes occur only in the central parts of the land.
    To be specific, after an earthquake occurred on September 30th of 1993, in the village named Killari, it was found that the land had risen about three feet in height.
    This shows that the rise of the land is the cause of the earthquake.
    Earthquake is the effect of the rise of the land
    On September 30th 1993, the earthquake that hit the village, killari, situated in central part of India resulted in the death of more than eight thousand people and raised the land surface about three feet high.
    This elevation was seen in an area of around two kilometers.
    Why did the earthquake occur?
    The quake occurred only in killari, situated in central India and left two kilometers of land area raised. This proves that the earthquake occurred only due to the rise of the land.
    Apart from this, the pictures taken by the satellite before the quake showed that the temperature of killari had also risen and the pictures taken after the quake showed it to be normal.
    After the earthquake occurred, on the borders of Andhra and Karnataka white colored smoke emitted from the ground.
    Why did the land rise? Why was the temperature more? Why did the land emit white colored smoke?
    We know that the molten rock material called magma is found inside the earth as we have seen it coming out through volcanoes.
    In the same way, when the molten rock, lava flows on the earth’s surface, we can see the condensed steam and other gases in the form of white colored smoke.
    As the water and other hot gases are eliminated as steam, the molten rock cools down and turned in to rock.
    In the same way when the molten rock inside the earth starts cooling, water and
    Other hot gases come out in the form of white smoke. Due to this, the temperature of the land rises.
    Moreover when the molten rock cools and as the water and hot gases get released, the rocky plates that are formed are of less thickness.
    For example: water has a higher density and the ice cubes formed from it have a lower density and float on water.
    Likewise, the molten rock material which has a higher density produces rocky plates which have a lower density and move above the level of the molten rock.
    In the same way, when new plates are produced by the molten rock material, they start moving upwards there by pushing the plates which were already formed. On account of this movement, the edges of the plates rub against each other thereby causing earthquakes.
    For example, in 1356 an earthquake occurred in the city Basel in Switzerland which is situated in central Europe .
    In the same city, an organization which produces electricity using the heat from underground, drilled two holes of five meters each on the earth in the year 2006.
    The project was to send cold water through the first hole which would be changed into steam using the heat of the molten rock and pushed out through the second hole and by rotating dynamos; this would be converted into electricity.
    But, on the eighth day after the water was sent inside the earth, in the same place, the Richter scale recorded an earthquake with an intensity of 3.4.
    Even if atom bombs are tested underground, earthquakes do not occur. How could the water which seeped inside produce an earthquake?
    This clearly shows that the water which seeped inside the earth cooled the molten rock which in turn formed new plates that rose up and caused the earthquake.

    The earthquake that shook the new Madrid city from December 1811 to February 1812, still remain a scientific mystery.

    Currently researchers believe that earthquake is an effect of rubbing of moving continental plates.

    But the problem is the city new Madrid is located at the central part of the North American continent.

    During the earthquake rising of some section of land created six foot waterfalls in the Mississippi river . And the land in the nearby city called as Tennessee uplifted, about 50 kilometers long and 23 kilometers wide.

    This rising of land changed the course of the Mississippi river permanently.

    Therefore I conclude that the earthquake was caused by the rising of the land.

    sinse the earthquake zone is situated at the central part of the continent the so called moving of continental plates can not be said as an explanation.

    it should be noted that when an earthquake occurred on 30.09.1993 in the killari village which is located at the central part of the peninsular India , land has been raised up to three feet hight and the rising of land has been observed up to two kilometer distance.

    therefore the rising of land is the only reason for the earthquake

      Proving a theory doesn’t happen just because you keep repeating the same phrase over and over again – try sprinkling some science on there too. “rising of the land” repeated numerous times and posted over and over again does not make it the true.and only possible cause of earthquakes.
