Japan to draw three-dimensional map of the West Island area expansion process can be demonstrated

due to volcanic eruptions area expanded three-dimensional map of Japan's Ogasawara Islands West Island

[Roundup] According to Cheap jerseys the World Wide Web Japan, "Asahi Shimbun" reported on April 18, due to volcanic eruptions expand the area of ​​three-dimensional map of Japan's Ogasawara Islands West Island recently completed drawing. Three-dimensional map of the island with a bump different shades of red, easy to understand displays a complex terrain west of the island due to the formation of magma flow. On the map you can clearly see the lava flow, such as dendritic Cheap NHL Jerseys dispersed, West Island gradual expansion cheapjerseys.us of this process of change can be clearly displayed.

reported that this map is used called "red-dimensional map" mapping method by aerial survey company, Georgia Institute of Chiba Dalem long aerial survey technician with the Japanese homeland geographic precision measuring hospital elevation data is made. On the map, part of the crater near crimson expressed ejected magma piled cone terrain. Spread its surrounding lava flows downstream into dendritic dispersed, large front slope. Figure February 16 and March 22 can be seen, even if the surface of the solidified lava Cheap Beanies flows, but the internal magma is still flowing, thus, the front has solidified lava flows constantly being broken, so that magma was sticks like spread. After the formation of a lava flow streams empty, culminating in the rear of the depression, becomes similar to magma dikes on both sides of the high terrain.

Chiba said that this is the first time so frequent and detailed measurements of the volcanic eruption in altitude, is an important change in the Research volcano.

based on the observation of the Japan Coast Guard, Cheap soccer jerseys country as of April 15, the West Island thing about 1150 meters, about 950 meters from north to south, covering an area of ​​0.75 square kilometers, about the size of 16 Tokyo Dome. According to the Japanese Geographical Survey Institute data show that as of March 22 West of the island's highest point is about 71 meters.
