Hikurangi Margin, located off the east coast of Northern New Zealand Island, is where the Pacific Creation segment sinks under Australian tectonics instant Australia.0: 00/2: Southern subdomains A electromagnetic sensor is taken to the bottom Ocean off New Zealand. In that, scientists called a sinking area. The surface of these tectonic placles is said to be part of the causes of more than 15,000 earthquakes in the region. Most earthquakes are too small to be noticed
. However, about 150 - 200 matches are big enough to feel. Geological evidence suggests that large earthquakes have occurred in the southern part of the edge, before people save data. Geophysics, geology and geography around the world have coordinated To find out why this area creates a series of "silent" earthquakes, unable to feel
Accordingly, the ocean floor in the north of the island has moving plates. Create into small earthquakes. However, at the southern end of the island, instead of moving slowly like in the northern region, the tectonic segment stood still. This phenomenon sets the conditions for the sudden release of the arrays. Since then, it is possible to cause a large earthquake. The electromagnetic geophysics from the Christine Chesley Sea at Columbia's Lamont-Doherty Earth Observatory and are the main author of the study, sharing: "That's those What we are trying to find out, the difference in this amplitude "in December 2018, a team has started a 29-day ocean expedition to collect data. They use electromagnetic wave energy to measure how the current moves on the ocean floor. From these data, the group has a more accurate view of the role of underground mountains in creating an earthquake. In fact, the underground mountains contain more water than expected. This level is about 3-5 times more than conventional ocean shell
Abundant water will lubricate tectonic places where they combine together. From there, prevent them from adhering to - the factor causes earthquakes. This helps explain the trend of light earthquakes at the north end. By using these data, Chesley and colleagues discovered an area in the upper array cracked by the underground mountain. This area seems to also contain more water. "That shows that the underground mountain is breaking the upper array, making it weak. This helps explain unusually silent earthquake models there. This example provides a different sign on how the tectonic segments affect tectonic behavior and earthquake risk, "Chesley said. Behavior, the lack of lubricant and impact impact of the arrays Creating can make the southern part of the island easily generated large earthquakes. . Dịch vụ:
