Executive Summary
Guatemala is a country that is very prone to natural disasters. It is a developing nation with many areas that must be addressed in order to take proactive measures, for disasters that may occur in the future. The following report will provide an in depth analysis of the Guatemala earthquake of February 4, 1976. This earthquake resulted in an estimated 23000 deaths, 76000 injuries, and over $1,100,000,000 in economic losses. This report will cover the disaster’s location, drivers, specific details related to magnitude, human activities, historically related information, and recommendations as well. There are many aspects of the Guatemala earthquake of 1976 that can be used when preparing for, and mitigating natural disasters that may occur in the future.
1.0 Disaster Location
Guatemala is a Central American country and is a nation that is very prone to major disasters. The country borders the North Pacific Ocean and is located between El Salvador and Mexico. The country also borders the Caribbean Sea between Honduras and Belize. Its geographic coordinates are 15.30 N, 90.15 W. The country of Guatemala has a total area of 108,889 sq km and its coastline is approximately 400km long (CIA, 2014).
The Guatemala earthquake of February 4, 1976 originated in the Motagua Fault and its epicenter was about 48 km southwest of Guatemala City. The tectonic ...

Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...
Earthquakes in California are certainly not a surprise. What is a surprise is their unpredictability and randomness. Geologists say there is roughly a 50 percent chance that a magnitude 8 or more quake will hit the Los Angeles area sometime over the next 30 years. And, over the past twenty years, the Los Angeles area has witnessed several earthquakes, and in particular, two that were quite devastating; the 1971 San Fernando earthquake, and the January 17, 1994, Northridge Earthquake. Given the certainty that earthquakes will occur, they still seem to come as a surprise, and leave many communities unprepared to deal with their aftermath.

Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...

On January 12, 2010, while vacationing in Santo Domingo, DR. Tragedy hit and my strong foundation no longer stood. An earthquake with a magnitude of 7.0 shook and uprooted homes, places of business and my sense of peace. After hearing news of the earthquake, I rush to Port-au-Prince to check on my family. I was reassured that my family was secured and had no life threatening injuries, but the same was not said to my grandparent’s neighbor. Their neighbor suffered from a head injury and deep laceratio...

The epicenter of the earthquake in Alaska was about 10km east of the College Fiord, approximately 90km west of Valdez and 120km east of Anchorage, Alaska largest city. The earthquake was felt about 1,300,000 square kilometers away from the epicenter. (Christensen, Doug PhD.) About 30 kilometers deep, the first slip occurred under northern Prince William Sound, and an 800 kilometer rupture in the rocks extended horizontally, roughly parallel to the Aleutian trench. (Bolt) The cause of this massive earthquake was the vertical displacement of northwest motion of the Pacific plate. Also, it was estimated that about 200,000 square kilometers of the crust were deformed, making this the greatest area of vertical displacement ever measured. (Bolt)
“An introduction to climate change.” Natural Resource Defense Council. Natural Resources Defense Council 8 November 2015 n. pag. Web. 28 November 2015.
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors. I...
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
