Week 5 Volcanoes

Image
Week 5: Volcanoes No volcanoes are known to be active in Taiwan, my chosen country. Compared to countries around Taiwan such as Japan and the Philippines, where volcanic eruptions occur frequently, Taiwan has no clear volcanic eruption records. The areas currently known by scientists to show signs of volcanic activity are  the Datun Volcano Group in northern Taiwan, the Guishan Island off the coast of Yilan, and the undersea volcanoes in the waters off northeastern Taiwan. Research has revealed that the last peak of activity at the Datun Volcano Group was about 800-200,000 years ago, and the last eruption was about 6,000 years ago, with no recent volcanic activity. However, it has also been found that there is the magmatic activity within the crust of the volcanic region, so the possibility of future eruptions cannot be completely ruled out. There was no information on countermeasures against volcanoes seen from people or policies living in Taiwan, but if you are near a volcano and...

Week 3 Earthquake

Week 3: Earthquake As mentioned in week 2, Taiwan is one of the very seismically active countries. Taiwan is located on a complex tectonic plate and is a so-called earthquake-prone country, including small earthquakes, with an average of about 90 earthquakes per month, or three per day. 2,415 people were killed in the 921 earthquakes mentioned in week 1.            After the 921 earthquakes in 1999, the information infrastructure of buildings and structures is being organized and earthquake preparedness models are being developed. In addition, information on where and how big an earthquake is quickly available to local people via smartphones and the Internet. The 1666-foot Taipei 101 building has a wind damper, a giant gold sphere, hanging inside the building, which is said to play a role in reducing the width of the building by 40%.  https://upload.wikimedia.org/wikipedia/commons/thumb/8/88/Taiwan_seismicity.jpg/400px-Taiwan_seismicity.jpg https...

Week 2 Plate Tectonics

 Week 2: Plate Tectonics of Taiwan This week, we discussed the importance of knowing the location of the plate and how it affects plate tectonics.   According to the idea of plate tectonics, the Earth's crust is divided into sizable rock masses known as "plates" that move across the mantle  (the layer of rock above the Earth's core).  In plate tectonics, the crust and upper mantle of the earth's lithosphere, its outermost layer, are separated into sizable lithospheric plates. The asthenosphere is a layer of rock that is partially molten and sits on top of these plates. The plates move in relation to one another at a rate of 1 to 6 inches per year due to convection between the asthenosphere and lithosphere.  The theory of plate tectonics, the slow movement of plates, has a profound effect on the planet we live on. It is largely responsible for the formation of oceans, continental mountains, and our disasters, earthquakes, and volcanic eruptions. https://www.inter...
