Historic Earthquakes Chile 1960 May 22 19:11:14 UTC Magnitude 9.5 The Largest Earthquake in the World Articles N.B. : The magnitude for this earthquake has been recalculated since the following articles were written. Magnitude 9.5 is a better determination of the size of this earthquake. More than 2,000 killed, 3,000 injured, 2,000,000 homeless, and $550 million damage in southern Chile; tsunami caused 61 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damge in Japan; 32 dead and missing in the Phillippines; and $500,000 damage to the west coast of the United States. Abridged from United States Earthquakes 1960, by H. Carroll Talley, Jr. and William K. Cloud.
In Mexico City of 1985 and San Francisco of 1989 there were big earthquakes. Many people died and may buildings were destroyed. About 100,000 people were killed and over 300,000 buildings were destroyed or damaged. Both of these Earthquakes were quite similar. The 1985 Mexico City earthquake was one of the most devastating earthquakes in the history of the Americas.
The fault system that split to result in this earthquake was the Enriquillo-Plantain Garden fault system. What were its effects on the environment? The greatest issue that the quake had on Haiti is the building waste. Before the earthquake even occurred, Haiti already had environmental complications. Combining these ecological issues with Haiti’s ever-growing population (now 9.7 million are increasing by 2.5 per cent each year) this becomes the result of millions of Haitians being forced to live in low areas like floodplains.
What is "summit deflation"? (page 94, para 2 to page 95) Summit deflation, which is measured by tilt meters in parts per million, is when the slope of a volcano changes usually relatively prior to an eruption. 4. How does Kilauea's magma move upward
Past disasters include the San Francisco earthquake of 1906 (magnitude 7.8) which along with subsequent fires destroyed much of the city. Droughts 1. Droughts in California can be caused by anticyclones (long-lasting periods of high air pressure with sinking, dry air. Dry, sinking air means no rain. 2.
How the 1906 Earthquake Marked the Dawn of Understanding Earthquakes And the Study of the San Andreas Fault in California On the morning of April 18, 1906 at approximately 5:12 in the morning, the city of San Francisco was awoken to one of the most devastating earthquakes in the history of California. The earthquake and subsequent fires caused an estimated 3,000 deaths and over half of the city’s residents were left homeless, and the once wealthiest and most important cities on the Pacific Coast was turned to ashes and ruins (Zoback). Before 1906, little was known or understood about earthquakes, how and where they occurred, or the risk they posed. Although the 1906 earthquake manifested a groundbreaking and tragic event in California,
Japan is a country that lies a hundred km from where tectonic plates are clashing at a convergent boundary, with one plate being dragged beneath the other. These tectonic plates are very thick rating, from 10km to 50km and are in motion with respect to each other. In Japan, they tend to move at rates of eight to nine centimeters yearly hence the result is a collision, with one plate forced to go beneath the other. If enough stresses build up from this sticking, then finally there will be a sudden slip which produces an earthquake. Japan is well known for being particularly amenable to subduction zone earthquakes, with huge pressures brought to bear by the sticking tectonic plate zones nearby it, and the slipping results in many earthquakes, some of them very big for instance the Tohoku earthquake.
Gonzalez Jesse Period 3 5/5/2011 Japan and Haiti’s earthquake Japan and Haiti, two countries that got hit by enormous earthquakes. Japan of the richest countries in the world, was shookened by a 9.0 magnitude after a tsunami and then nuclear crissis. Haiti, one of the poorest countries, got hit by a 7.0 earthquake and then an outbreak known as cholera. Japans earthquake caused a lot of casualties , damage, and weakened its economy. Haitis earthquake had casualties, a lot of damge, and their economy was weaker than it was.
The deadly earthquake caused a large amount of damage and death in the country and in the pacific coastal areas. Also the tsunami that took place afterwards was the result of this earthquake, which is said to be the largest earthquake that ever happened. According to the Chilean government they estimated around 2,000,000 people were
