Ladies and Gentlemen:

Mr. J. Howard had asked the following persons to do a study on Earthquakes:

Laura.

Mr. Howard asked the following questions to be answered by Laura

Where the most recent earthquakes are occurring and if they are more likely to occur in certain locations.

Whether or not there is any way to determine what parts of the world are most prone to them.

If there is a relationship between earthquakes and volcanoes.

What is causing the earthquakes.

Those questions have received the following answers.

The most recent earthquakes are occurring in Japan, Philippines, the West Coast of South and North America, New Zealand, Mexico, the South Coast of France, Southern Australia (only one), South-West Alaska and the furthest reaches of Eastern Russia.

There is a way to determine what parts of the world are most prone to earthquakes. Ignoring the solitary earthquake in Australia, we can see on this map that other earthquakes are occurring on plate borders. This is how we determine where earthquake-prone areas are.

There is a definite relation between earthquakes and volcanoes. Ocean plates slide under Ocean or Continental plates, causing an earthquake. The plate that has been pushed under another disintegrates, and most of the newly formed lava rocks go down, but some goes up to the surface, causing volcanic eruptions and/or a newly formed volcano.

The final question ‘What is causing earthquakes?’ is a tricky question to answer. While we are still learning about the Earth’s structure, scientists have constructed models to stimulate movement of the lava flows deep inside the earth, and have concluded that what is causing earthquakes is plates crashing together. When the tension of long periods of time is released, it sends shock waves rippling through the earth. The epicentre is often the point with the worst damage done.

There are your questions and their answers, Mr. Howard.

Yours Sincerely,

Laura

  • Most of the earthquakes plotted seem to appear in the same approximate areas. There are clusters here and there all over the world; some of these clusters appear in southern Greece, in Turkey, and West of Northern Iran. Another cluster appeared in Eastern Sichuan, China, most of which happened on the same day, one was major, a 7.9 on the Richter scale, another, just an aftermath, was 6.0 on the Richter scale. All the others were, too, extreme aftermaths.
  • A very common pattern that seems to occur is that earthquakes usually happen near, or on Fault lines, the “border lines” of tectonic plates. One, in South America, specifically, Ecuador, happened directly on a Fault line, but it was not a big fatality; it was only a 4.5 on the Richter scale. It may be ironic, but some people would expect more fatal earthquakes to appear directly on fault lines, but that is not the case every time. As a matter of a fact, The Eastern Sichuan earthquakes were 150 (approx.) miles away from the fault line.
  • High risk locations for earthquakes would definitely be around the Ring of Fire, especially Eastern Honshu, Japan. Another “hotspot” would be the San Andreas Fault, running along western California.
  • The President should know about how dangerous the San Andreas Fault line could be. We could have a horrible 7.9 earthquake, just like Sichuan, China, and most likely, we would be unprepared. Nobody knows for sure when “The Big One” will hit, but everyone knows it will come eventually.
