Week13 Coastal Hazards This week I would like to discuss the Coastal Hazards in Taiwan. Taiwan's long coastline and low-lying coastal regions raise serious concerns about sea levels and coastal issues. Taiwan's coastal issues and rising sea levels are primarily caused by land subsidence, climate change, and extreme weather. I'll talk about a few of the specific issues, their root causes, and potential solutions. Sea Level Rise Melting glaciers and ice sheets, thermal expansion of the ocean, land subsidence, and extreme weather events are all contributing to the problem of sea level rise in Taiwan's coastal areas. To address this problem, Taiwan has come up with adaptive solutions such as building seawalls and coastal levees, moving communities along the coast, and encouraging the use of renewable energy to reduce greenhouse gas emissions. Coastal erosion Removal of vegetation and natural barriers, as well as the construction of seawalls and other structures, are the ma

 Week10: Extreme Weather This week I would like to discuss the extreme weather conditions in Taiwan.  Taiwan is characterized by a temperate climate, with warm and pleasant winters, but very hot summers and happened thunderstorms from Typhoon, with an average summer temperature of about 90°F. On the other hand, the region is blessed with a relatively pleasant climate with an average minimum temperature of about 50°F in winter. The problem of extreme weather in Taiwan in recent years is not something to be taken lightly. Summer precipitation has become abnormal, and in winter, rainfall is so low that there is a possibility of drought conditions from rising average annual temperatures. The reason for the increase in summer precipitation is that global warming has increased the occurrence of typhoons, and the strong winds from the west that blow in summer cause typhoons and precipitation to increase. This may be an aside, but the fact is that in 2020, for the first time in 56 years at th

  Week 8: Mass Wasting Events This week we will discuss a mass wasting event in Taiwan. Taiwan is one of the countries prone to landslides due to a combination of rapid rainfall events, typhoons, and periodic earthquakes. According to my research, the landslide probability in Taiwan was 0.5% to 2% until 2009. https://blogs.agu.org/landslideblog/files/2017/05/17_05-Taiwan-1.jpg However, after 2009, a drastic change occurred in southern Taiwan and the landslide rate increased dramatically. Northern Taiwan was unaffected, but southern Taiwan was hit by typhoons that brought massive amounts of rainfall, resulting in horrific landslides. Taiwan is prone to typhoons due to the winds, with many typhoons occurring offshore in areas east of Taiwan or south of Japan. 2009 saw Typhoon Morakot, in which more than 700 lives were lost due to the typhoon. 2010 also saw a landslide that partially buried a highway, killing several people. There have been other disasters as well. https://blogs.agu.org/l

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 it

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://cdn.britannica.com/29/93629-050-BE1D

 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.interne
