Earthquakes throughout History:
The Earthquake Q&A By: Sean Sheva and Richard Lin Before we start, for the people who don`t know a lot about earthquakes, Here`s some Q and A's that should help you learn about earthquakes. An earthquake is when two tectonic plates collide, and /or grind along the side,(like a flint and steel, the friction causes a spark that can start a fire) causing friction that stores energy and creates an earthquake. How does an earthquake happen? The San Francisco earthquake of 1906 The Great San Francisco Earthquake of 1906 What can a Earthquake Trigger? The Great Earthquake of San Francisco (1906) An earthquake can trigger a few unfortunate
things like tsunamis (when a gigantic tidal wave moves onto a land mass and fall back) and Land slides (where a chunk of land disconnects from is original mass causing it to, if at a steep angle fall). Or earthquakes can
trigger aftershocks (like small earthquakes), or like the
earthquake in Japan, a nuclear meltdown (explosion). The earthquake occurred at 5:16 on a peaceful morning when two miles of shore (at the epicenter of the furious earthquake) exploded. An earthquake had occurred. the earthquake had a magnitude of 7.8 and started ferocious gas fires that went on for 4 straight days! After the earthquake ended, 70% of San Francisco was destroyed and over half of the population became homeless. What type of tool can be used to measure the strength of an earthquake? scale of 1-10. When measuring the strength of an earthquake
scientists use a seismometer. Another way of measuring
the strength of an earthquake is using the Richter Scale.
The Richter Scale is a way to measure earthquakes on a What Exactly is a Seismic Wave? A Seismic Wave is a giant wave that moves through the earth's
core. What was the Strongest Earthquake? The strongest earthquake was in 1960 in Chile. It had a magnitude of 9.5 on the Richter Scale. Is There Such Thing as the Center of an Earthquake? Actually yes, there is. That is called the epicenter (The point on the surface where the center of the earthquake is located. That is also where you will find the geographical location of the earthquake). Scientists find the epicenter of an earthquake by looking at the speed of the seismic waves. Timeline of Earthquakes The Strongest of Them All:
The Earthquake of Chile (1960) The Earthquake of Haiti
(2010) The Devastating Earthquake of Japan
(2011) (Yes, there are more than five earthquakes,
but these are just the ones we decided to study.) The Near Present Time The Great Earthquake of Chile
occurred on May 22nd, 1960. Its magnitude on the Richter Scale
was 9.5; making it the strongest
earthquake ever to take place in recorded history. This earthquake killed about 1,655
people and destroyed a total of 130,000
homes. And the earthquake didn't end there;
it also created tsunami`s that carried onto
Hawaii, New Zealand, and even Japan(The Tsunami arrived 22 hours after the earthquake, was about 30 ft high and came from almost 6,200 miles away)! Not to mention, multiple landslides occurred on the sleep cliff`s of the . The Past This earthquake struck
on January 12th, 2010 at
4:53 PM I had a magnitude of 7.0 on the
Richter Scale - A fairly strong earthquake An estimated 250,000
people were killed due to
the earthquake. Buildings Destroyed
- about 30,000 commercial buildings
- about 250,000 residential buildings This earthquake also caused a localized tsunami This earthquake happened on March 11th, 2011 On the Richter Scale this earthquake
measured as a 8.9 which is a very strong
earthquake (Only .6 less than the earth-
quake in Chile) Hundreds of bodies found,
but the government believes
that thousands died (Over 10,000
people) Thousands of homes destroyed This earthquake not only triggered a gigantic tsunami,
it also created a terrible nuclear explosion from one of
the nuclear power plants. That's All! Loma Prieta Earthquake
(1989) The Loma Prieta earthquake occurred on
October 17th, 1989 at 5:04 PM This earthquake received a 6.9 on the
Richter Scale Luckily, this earthquake only killed 63 people although it left 3,757 people injured This earthquake damaged about
12,000 homes and about 2,600
businesses Although there was no tsunami
involved with this earthquake,
this earthquake did occur during
warm up practice of the third game
in the 1989 world series. A video before and After the Earthquake Other Statistics on the 1906 San
Francisco Earthquake

In total, the 1906 San Francisco earthquake took the lives of a total 664 people:
-498 people in San Francisco
-64 in people Santa Rosa
-and 102 people in San Jose
