Earthquakes:

A Deadly Natural Disatser

What earthquakes are and more informaion about them.

An earthquake is what happens when two blocks of the earth (plate tectonics) suddenly slip past one another. This happens near plate boundaries (refer to the picture on the far left below). The most popular locations are around the ring of fire (refer to the picture in the middle below, also the rest of the locations are near the Ring of Fire), San Andreas Fault in California (refer to the picture on the far right below and the bigger photo below the three other photos and one photo below that), Alaska, and India, however there are many locations not stated in this list. Also you can look at the picture below all of the other photos to see the top states that receive earthquakes.

Large Earthquakes in History

There has been many devastating earthquakes, but two really turned my eye, the Alaskan earthquake of 1964 and the Chile earthquake of 1960. First we will start with Alaska and its powerful Earthquake then move on to Chile's Earthquake.


On March 27, 1964, at 5:36 p.m. a great earthquake of magnitude 9.2 occurred in Prince William Sound region of Alaska. The number of deaths from the earthquake totalled 131; 115 in Alaska and 16 in Oregon and California and costed over $311 billion in damage (today’s amount) which was surprising because the earthquake was so powerful, but this was due to low population in these ares. The earthquake also did not have a huge impact on the economy also due to low population. There are also some photos below from the earthquake.


Now for Chile's huge Earthquake of 1960. On May 22nd, 1960, at 7:11 p.m. an earthquake with a magnitude of 9.5 occurred 100 miles off the coast of Chile, parallel to the city of Valdivia. Near coast of Chile the magnitude 8.3. More than 2,000 killed, 3,000 injured and $550 million damage ($72,000,000 today) in Chile. It has been estimated that about 40% of the houses in Valdivia were destroyed, leaving 20,000 people homeless. There was a some impact on Chile's economy. It didn't export as much as they did and they were in debt for a little while. There are photos from the disatser below.





More Information

There is some other interesting information about earthquakes. The first is that there is no technology that can help much with predicting earthquakes. The damage earthquakes could cause (mainly depending on how big they are and where they hit) could cost billions in damage and many people dead or injured. Lastly I looked fot humanitarian groups that help with earthquakes but only found the Red Cross (see picture below).
