8 H October 26, 2012 1886 Charleston Earthquake In Charleston August 31, 1886, a devastating earthquake shocked millions throughout the country. Not only was this earthquake reported in South Carolina, but in distant places such as Boston, Massachusetts, Milwaukee, Wisconsin, Chicago, Illinois, Cuba, Bermuda, and many more. Why so many places? The earthquake recorded a 7.4 on the Richter scale. This tells us that it’s a powerful earthquake, reaching and being felt by farther away places.
The lack of food, power, and heat affected absolutely everyone emotionally and physically, causing the sociology of disaster. It changed everyone’s daily routines and everyday life, including mine. Living in the United States for the first time in my life was probably the biggest adjustment I’ve ever had to undergo. I’ve lived on the small island of St. Croix in the US Virgin Islands my entire life. It was hard enough moving thousands of miles away from my home, but being a part of a place that was completely destroyed by a hurricane was beyond my wildest predictions of being here.
Why did so many people die in Haiti’s earthquake? The earthquake that hit Haiti in 2010 was only a magnitude 7.0, a hundred times weaker than the earthquake that hit Japan a year later; yet the severity of the damage caused was completely different. There are several reasons for why the Haitian earthquake was able to cause so much damage, but some of the major reasons are because of Haiti’s location relative to the tectonic plates, the low level of development of Haiti, the time of day the earthquake hit, and the history that lead up to the current state of Haiti. Haiti is a country located on top of the Caribbean plate which is in between the North and South American plate. This poses a great earthquake hazard to Haiti.
The belt extends from Chile, northward along the South American coast through Central America, Mexico, the West Coast of the United States, and the southern part of Alaska, through the Aleutian Islands to Japan, the Philippine Islands, New Guinea, the island groups of the Southwest Pacific, and to New Zealand. This earthquake belt was responsible for 70,000 deaths in Peru in May 1970, and 65 deaths and a billion dollars' damage in California in February 1971. As disaster crews and scientists examine the havoc wrought in Haiti, questions emerge as to whether such a vastly destructive disaster could happen at home in the United States. Would citizens know how to react? Cities are located near dangerous earthquake zones all throughout the country, from the most infamous on the West Coast to potential time bombs in the Midwest and even on the Eastern Seaboard.
There was an earthquake that happened on September 9th, 2012 in Oklahoma which was a 3.4 magnitude (USGS, 09/11/2012) 3. What patterns do you see in the distribution of earthquakes around the world? In researching the global earthquake it looks that the region called the Pacific Rim of Fire is the most active of all around the world. This area is noted for its seismic activity as four major tectonic plates converge in this region. These plates are the Pacific Plate, the Eurasian Plate, the Indo-Australian Plate, and the North American Plate.
(United States Geological Survey, Science for a Better World, N.D. p. 2) Unzen’s mixture of proclastic flows, dome collapses, and generation of landslides and tsunamis has caused the loss of thousands of lives. Location and Geology Unzen is on the Shimabara Peninsula of Kyushu Island. This island is in southwest Japan. (Umakoshi, Itasaka, & Shimizu, 2011) It is located where the Pacific and Philippine plates are subducting under the Eurasian plate. It is within the ring of fire.
Multiple hospitals and schools were damaged and the most recent update is that 19 cities and towns have been declared in a state of emergency because of structural damage which has effected 1,500 and 22,000 people. Mexico City has a high tech warning system for earthquakes which they utilized the morning of the 21st of August. After a terrible 8.1 earthquake in 1985 which killed 6000 people and destroyed many buildings in Mexico City from a location 250 miles away Mexico decided to implement their warning system. “Mexico City's earthquake warning system relies on a network of sensors that detect earthquakes in the seismically active zone along its Pacific Coast. Since electronic signals travel at 186,000 miles per second, much faster than the 7,000-mph speed of seismic waves, warnings can be sounded in Mexico City, some 150 to 200 miles away, with a minute or two of
Before the actual earthquake, there were several foreshocks. The actual earthquake caused more than 600 aftershocks bigger than magnitude 4.5 with the biggest aftershock of 7.7, 30 minutes after the first quake. The earthquake triggered a tsunami which travelled up to 10 km inland in the Sendai area, which caused loss of life, destruction of infrastructure and also a number of nuclear accidents, which included the Fukushima Nuclear Meltdown. The short term impacts of the Tohoku Earthquake is: loss of life, destruction of infrastructure causing transportation and delivery issues, radiation scare to the population , radiated food supply source, money spent to rebuild buildings, clean up, stocks fell. The long term impacts include: distrust of other nuclear facilities, loss of confidence in TEPCO (Tokyo Electric Power Company), distrust to the government to keep the population safe, Tohoku's agriculture and fishing industry being restored, destructions of farmland, traumatisation.
2011 Tōhoku Earthquake and Tsunami: Aftermath Problems On March 11, 2011, the largest earthquake in Japan’s history struck off the northeast coast of Japan. The epicenter was located about 80 miles from the shore of Tohoku, approximately 20 miles under water, and with a magnitude of 9.0, given by the Japanese Meteorological Agency (JMA) and the U.S. Geological Survey (USGS). It ranked second only to the Sumatra earthquake and the Indian Ocean Tsunami of magnitude 9.1 in 2004 (Hatake). The Tohoku earthquake triggered powerful tsunami waves, which traveled well into the mainland, damaging many buildings and infrastructures, not to mention lives. Additionally, over five hundred aftershocks of magnitude 4.5 or greater have occurred since the initial quake (Ananda).
