The place where they moved are called fault planes, the epicentre is the surface of the Earth that is above the hypocentre, where the earthquake starts. Earthquakes are followed by aftershocks, which are smaller earthquakes caused by the tectonic plates settling. Earthquakes can occur at anytime, in any state, no matter the weather, climate, time of day, or year. Earthquakes can also be small and big. A small earthquake may cause things to fall of shelves, but a large earthquake can cause serious damage, like taking down a huge building.
• Aerial Island’s entire source of agriculture is located within Zone A, with the highest risk of being destroyed by the eruption. If not already destroyed, acid rain (caused by sulphur dioxide) can affect crops directly and reduce yields from agriculture. Livestock and other animals will be killed by lava, pyroclastic flows and gases. • Lahars are mudflows flowing at very fast speed. When moving, it resembles a mass of wet concrete carrying rock debris.
Global warming plays a large part in the cause of drought. A. Global warming causes many deadly effects that people often ignore, as they don’t believe the reason of effects is global warming, but global warming truly causes many problems. 1. Global warming is causing rising seas which dramatically effect all sorts of different things.
Because japan is on top the subduction zone of the boundary of four tectonic plates: the Pacific, North American, Eurasian and Filipino plates Earthquakes are common and result from a fault that circles the Pacific Ocean, causing earthquakes on the west coast of North and South America as well. They are frequent in Japan, occurring more often than they are felt. Even so, one big enough to be noticed occurs every three days in Tôkyô. Occasionally they do serious damage. Tidal waves occasionally result from undersea earthquakes, and typhoons sometimes hit Japan as they move north from the South Pacific.
All of these causes bring countless effects environmentally, economically, socially and even politically. The repercussions, consequences and ultimately the chain of effects are generated after such disaster occurs. Earthquakes are without a doubt, one of the most fatal and destructive natural phenomena mankind ever experiences. One small effect can bring a thousand more struggles. Earthquakes’ effects range from many aspects, one of which is in terms of environment.
INTRODUCTION A. Background of the Study Earthquakes are one of the disastrous events which continue to endanger human life (Li, 2015). Thousands of lives and properties were lost during earthquakes such as: Tohoku Earthquake in 2011, Bohol Earthquake in 2013, and Nepal Earthquake in 2015. Effects of earthquakes differ depending on the location of the source. In major land masses, they often result to landslides and volcanic eruptions.
Landslides are caused by a combination of both natural and human related causes. In rawalakot, Azad Kashmir, it is studied that all mountainous areas are either exposed to or currently facing serious soil erosion because of high rain fall. According to metrological department reports an intense rainfall occurs in rawalakot and in its surroundings during the months of July and august and average rain fall calculated during these two months ranges from 112 to 136mm. Due to these shortcomings mountain disasters such as landslides have had significant impacts but limited mediations exist to minimize it or its effects. Further studies of literature and local people discussions results that the other main cause of many landslides in the study area was human activities which included cultivation, deforestation and terracing of steep slopes.
Most importantly, landslides can result to huge damage and loss of life There are many different causes which can result to a disastrous landslides. Both natural factor and man-made factor could trigger to the occurrence of a landslide. Naturally, a prolonged, heavy rainfall is the main cause as to why landslides happen. If a slope is saturated and lubricated from the rainwater, there will be less friction to overcome, resulting the slope to collapse. Natural events such as earthquake and volcanic eruption ensue landslide to happen simply from dislodged materials and earthquake tremors.The occurrence of earthquakes in steep
Natural disaster like typhoons and storms is very common in the Philippines. It causes storm surge along coasts and trigger landslide and flash flood in the mountains. A number of typhoons or storms hit the Country every year especially in Cagayan de Oro and it affects enormous quantity of people in the country. Flash flood is a perfect and a common outcome and issue when sudden storm unleash a torrential down fall or heavy rainfall occurs, runoff moves with a surprising force. The Center for Research on the Epidemiology of Disasters (CRED) described a flood as “a significant rise of water level in a stream, lake, reservoir or coastal region”.
Natural disasters are sudden and major adverse events caused by forces of environment that result in destruction of human life and infectious organisms, including the destruction of property. These natural processes of Earth causes a wide range of aftermaths, for instance the earthquakes, flood, tsunamis, windstorms, volcanic eruptions and other geologic processes. According to Chand (2014), the Himalayan Tsunami that happened in Uttarakhand has caused a total of 5,748 people been presumed dead by the State Govt. and hundreds of buildings and houses lay in ruins. The most prominent of natural disasters will be examined including hydrological, geological, and climatological disaster (refer to Figure 1 in Appendix 1).
