The Myanmar virus earthquake video shows the first visual guide on rare seismic phenomena

In May, we reported the first unique The video that took the roof rupture During the devastating Myanmar earthquake 7.7 volume. While YouTube video She now has 1.6 million views, two geophysical scientists have monitored something that many people may not notice.

The video seems to be a gift that continues to give. Kyoto University scientists also explain Ticket It was published last month in the seismic registry, and also includes the first direct visual evidence of the pulse rupture and the sliding of the curved rift. This means that the two sides of the sliding error were not horizontally bypassing each other-just as the slipping path decreased down. While scientists have previously concluded both the features of seismic data, post -Earthquake notes and seismic data, the video provides direct visual evidence.

The researchers wrote in the study: “Our results provide the first direct visual guide to the sliding of the curved kiusi rift, and a critical gap between seismic notes, geological data, and theoretical models.”

You may wonder how the researchers concluded all this from very brief video excerpts. The answer is that they analyzed a mistake in Myanmar in the framework of the shots. With this approach, they discovered that the error was sliding 8.2 feet (2.5 meters) in 1.3 seconds, with peak speed From 10.5 feet (3.2 meters) per second.

While the entire side movement in the earthquake was normal for the strikes of the strike, “the brief period of the movement confirms the pulse -like rupture, characterized by the spread of the slide along the error, such as a ripple from the University of Coat, he said at the university when it was transferred from one of the parties.” statement.

Kearse analysis and co -author Yoshiro Kaneko also revealed that the rift’s sliding path was a little curved. This discovery is in line with curved slickeenlines lines – conflicts caused by rocks that are embodied against each other at all wrong – that geologists in earthquakes often find it after earthquakes. The video provides the first visual guide to the curved slide behind the descent.

“Instead of moving things directly via the video screen, move along a curved path that contains a convex bottom, which immediately began ringing bells in my head,” Ceres explained in A. statement By the American Seismology Association. He adds: “The dynamic pressure of the earthquake, as it approaches and begins to tear the error near the surface of the earth, is able to stimulate the movement of the rift.” “These transient pressure pays the error from its intended path in the beginning, then picks itself and does what it is supposed to do, after that.”

On a wider scale, the teenager of the Myanmar earthquake from north to south confirms the conclusion of the former researchers that the types of slipping bend dependent on the direction of the aforementioned rupture. Accordingly, earthquake scientists can study Slickenlines to understand internal earthquakes, and possibly inform future risks.

“Together these results impose restrictions on critical observation of a rupture simulation in the future,” researchers are concluded in the study, “and deepening our understanding of the physical mechanisms that control the slide of rapid rift during large earthquakes.”
