best this excerpt came from Voltaire’s Candide a French satire published during Europe’s Age of Enlightenment. This gives a chilling view of Lisbon on All Saint’s Day (November first) in 1755. What had occurred is a 200 km offshore 8.5-9.0 magnitude earthquake that resulted in a large-scale tsunami and rampaging fires, effectively killing thousands of people. This is one of the deadliest tsunamis recorded in history, but how do tsunamis function and what do we know about their inner workings.

January 12th, 2010, Tuesday afternoon, a fierce earthquake struck Port-au-Prince, Haiti causing a crowded hospital to collapse, leveled countless dwellings, and brought even more suffering to a nation that was already the poorest and most disaster-prone in its hemisphere. Haiti has also gone through multiple previous natural disasters. When Haiti was a French colony, French historian recorded many earthquakes. In Port-au-Prince in the year 1757, one earthquake was so big that only one stonework building

kind of people use it, to children of 5 years up to old timers. A recent earthquake showed that the “ShakeAlert System” really works. 10 seconds before the start of the 6.0 magnitude earthquake in California, a group of investigators of the university of UC Berkley received an alert that the earthquake was going to happen. Therefore, the objective of this system is to alert you 40 or 50 seconds before the earthquake, this will be very helpful. But now a 10 second “alert” will be enough time

Last February 6, a 6.4 magnitude earthquake hit Taiwan. With 116 deaths and widespread damage, it is the deadliest earthquake the country has ever experienced for 1095 years. Two days after, another 6.4 magnitude earthquake shook the grounds of Papua New Guinea, with a minimal damage and zero casualties. And just two days ago, New Zealand experienced a tremor of almost the same scale, categorized as severe. While damages are at a minimum based on the latest evaluation, it is clear that a movement

Chile is located in South America, bounded on the east by the Andes, the world's longest mountain range, and the Pacific Ocean on the west. Peru borders Chile on the North; Bolivia forms the northeast border. Chile’s size is roughly similar to Turkey, considering only the continental territory. Chile includes three geographical zones. The first is so-called continental zone, which includes territory from the west coast to the high mountains in the east. Chile’s continental zone is a long and thin

("Geography.about.com", 2016). The Pacific Northwest has a lot of tectonic activity causing many earthquakes. The three tectonic plates that influence these earthquakes are The North America, Juan De Fuca, and the Pacific plate. These three plates make up what is called the Cascadia Strain. The most common damaging earthquakes in Washington and Oregon are deep earthquakes from Juan De Fuca. These earthquakes occur when Juan De Fuca starts to bend and plunge underneath North America. Stresses cause faults

an earthquake, also known as a quake, tremor or temblor is the result of a sudden release of energy in the Earth's crust that creates seismic waves. In its most general sense, the word earthquake is used to describe any seismic event either natural or caused by humans. Terminology The point at which an earthquake occurs is known as the focus.. Epicenter is the point on the Earth’s surface directly above the Focus. When the epicenter of a large earthquake is located offshore, the seabed may

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events. Plate tectonics is a relatively new theory that was developed by Alfred Wegner in 1912 who came up with the idea of Pangea which tells us about the structure of the earth. The earths structure consists of a crust which varies in thickness from 5 to 10 km beneath the oceans to 70 km under continents. The lithosphere is the next part which consists of the crust and the upper mantle and
