The earthquake rupture started approximately twenty five kilometers beneath the surface, with its core about six miles (ten kilometers) east of the mouth of College Fiord and seventy five miles (one hundred and twenty kilometers) east of Anchorage. The earthquake lasted approximately four and half minutes and is the most powerful recorded earthquake in U.S. history. It is also the second largest earthquake ever recorded, next to the magnitude 9.5 earthquake in Chile in 1960. The aftershocks were about two hundred and fifty kilometers wide and they extended eight hundred kilometers. The main shock occurred on the fault boundary between the Pacific and North American plates.
Fukushima Nuclear Disaster: Analysis of Safety On 11th March, 2011, Japan experienced an earthquake in the Tōhoku region, of magnitude 9.1 on the Richter Scale. This resulted in a devastating tsunami that affected millions of people. The tsunami also caused three reactors in the Fukushima Daiichi Nuclear Power Plant to malfunction, leading to a nuclear meltdown and release of potentially lethal radioactive material into the surroundings. The Tōhoku Earthquake ranks fourth on the list of all time worst earthquakes in terms of magnitude. As a result, the tidal waves it generated were huge, with the crests reaching up to 15 m in height.
This earthquake caused 60 deaths, 9,000 people injured. Causing the San Fernando Valley a total pile of destruction (TheAtlantic.com). What was actually the main cause of the Northridge earthquake? Why did the Northridge earthquake caused so many destruction? The earthquake happened because of the movement from the San Andreas Fault (u-s-history.com) .This little movement from the tectonic caused big things such as earthquake, but what exactly is San Andreas Fault?
Environmental disasters have taken the lives of many people and animals. It has produced many economic issues as well as a copious amount of air pollution. In addition to the calamities of environmental disasters, weather disasters have amplified the disaster rates tremendously in history by thousands. The weather if hot, cold, or wet has affected people worldwide over a vast amount of land. And lastly, war has claimed the lives of millions of people simultaneously from the beginning of time.
It is estimated that ten thousand people die each year worldwide due to hurricane’s. Hurricanes are large swirling storms that produce winds of one hundred and nineteen kilometers per hour or higher. Hurricanes form over warm ocean waters and sometimes they strike land. When a hurricane reaches land, it pushes a wall of ocean water ashore, known as a storm surge. The heavy rain from the storm surge can cause extreme flooding to occur.
As conditions became favorable, it started barrelling toward the Gulf Coast. It made landfall at Buras-Triumph, Louisiana as a category 3 hurricane. The winds of Katrina were 200 kilometers per hour and its storm surge reached 8 meters above sea level. This damaging storm killed 2,000 people and caused 108 billion dollars in damage. After Katrina, many conclusions regarding hurricane intensity were evaluated.
Nevado del Ruiz Case Study The Eruption and its Impacts What happened? On November 13th, 1985, the Nevado del Ruiz volcano erupted triggering destructive lahars, which caused approximately 23 000 human deaths, 4500 were injured and, following the catastrophe, 8000 became homeless . Signs of seismic activity can be traced back to July of the same year, where seismograph on the mountain showed uncharacteristically seismic activity levels . Later, in September 1985, not only had the level of seismic activity increased in the region, but steam explosions accompanied them . In November, seismic activity was observed near the summit of the volcano .
Hurricanes have led to the death of around 200 million people, over the past 200 years. Hurricanes usually form in tropical areas of the world.Hurricanes are large, spiraling tropical storms that can pack wind speeds of over 160 mph and unleash more than 2.4 trillion
(History, 2017) About 230,000 people were killed due to the earthquake, and more than 300,000 people injured. The earthquake created $7.8 billion to $8.5 billion in damages, 106,000 people were left without homes and 188,383 homes damaged. About eighty percent of schools damaged or destroyed. (Amadeo, 2016) November 19, 2010, more than 19,000 transitional
INTRODUCTION Catastrophes affect humanity all the time but two of the most memorable in history are Hurricane Katrina and Hurricane Harvey. Hurricanes are first seen from the satellite. This means that the hurricanes are spotted right away, it gets predicted where its going to impact first and how strong it can be when it hits the ground. These hurricanes are extremely dangerous because of its high-speed winds it comes with and the amount of rain produced by them, this makes it worst because they can last for days. The two most recent Hurricanes Harvey and Katrina impacted differently, they both had fatalities, damages and occurred different years.
