The first type of video showing ground cracking during a major earthquake is far more notable than the previous thinking. It not only captures a ground movement that has never been caught on the video before, but also shows the crack curved as it moves.
This curvy movement is estimated from the geological record and from the “silicon lines” – the scars that are on the sides of the mistakes – but the geo -physicist, was never seen in the process. Jessi CareceCurrently, a post office researcher at Kyoto University in Japan said in a statement.
“Instead of straightforward things across the video screen, he went on a curved path that had a stimulus downward, which immediately started ringing in my head,” Kerise said, “Kerris said,” Because some of my previous research has been particularly on the slip of the slip, but with a geological record. “
Video – Caught by a security camera near Thazi, Thazi – shows the ground bursting during one On March 28, the region’s magnitude 7.7 earthquake. It shows the earth shaking, then the crack opens. During the major earthquake, the ground breakdown is relatively common, but they were never caught on the video.
Kerris said he saw his spinal cord immediately after uploading the video to YouTube. Upon seeing his fifth or sixth, he saw that the crack was a curved letter. He and his fellow Kyoto University, in Geo -Physicist Yoshiro KanikoThen analyzed the video more closely. They found that the crack curved letters first accelerate in the first and then the speed of speeding at 10.5 feet per second (3.2 meters per second) is 8.2 feet (2.5 meters) in 1.3 seconds at the speed of movement. After hitting its high speed, the crack becomes straightforward and slow.
The results show that rotation occurs at this time as the pressure on the ground surface is less than the deep pressure in the ground. How it makes a mistake makes an uneven pattern. “Kerais has important information about the dynamics of rotation.” The interpretation video of this slip that he posted on YouTube.

Kerris said in the statement that different pressures at the surface remove the error, and then it catchs itself and does what he has to do. “
The dynamics of these rotation depend on how the break -up journey travels, so the understanding of curves can indicate how past earthquakes come and help scientists better forecast the future groundbreaking.
Researchers posted their results, which have not yet been reviewed, on print print database Arthur arcio June 16.
