Links To Learn More About Samoa & Sumatra Earthquakes

There have been two earthquakes many miles apart that have killed a number of people.

(Above–Damage and injury in Sumatra as photographed by Singallang Newspaper and distributed by Reuters.)  

One of these earthquakes has killed many people in Samoa and American Samoa.

The other has strongly impacted the island of Sumatra. Sumatra is part of Indonesia. 

It is not clear if the two earthquakes are related, but the two quakes do not represent an unusual amount of seismic activity on the Earth.

Here is information about earthquakes. No doubt you have heard about earthquakes many times, but do you really know what the word means?

Here is a global map of major earthquakes in the past five years.

The earthquake that has hit the Samoan Islands took place offshore and caused a tsunami that has swept across the islands. Here is specific information about tsunamis.

Here are some basic facts about the Samoan Islands.

Here are some basic facts about the island of Sumatra.

The death toll from both these earthquakes will likely rise in the days to come. Aid is needed. This link lists many groups offering assistance.

In the end, it is up to you to learn about the world around you and to offer help if you are able.

In The Midwestern Earthquake I Felt, People Ignored It As If It Happens Everyday

The Midwestern earthquake earlier this morning was no real surprise.

( Above you see a map of the epicenters of Midwestern earthquakes since 1974.)

This earthquake, centered in southern Illinois, was 5.2 on the Richter scale.

There was little damage.

Here is an explanation of the Richter scale. 

The New Madrid fault zone is the source of many of these earthquakes. Here is information on that fault zone from the U. of Arkansas at Little Rock. 

The 1811 & 1812 New Madrid earthquakes were very powerful. 

Here is the Earthquake Hazards Program of the U.S. Geological Survey.

I was in a Midwestern earthquake in Cincinnati, Ohio in 1980. I was 12. I was at a movie theater when it happened. The theater shook and swayed.

My mother and I got out of our seats and walked to the lobby to try and figure out what was going on. Many others did as well. This seemed like a normal reaction to shaking and swaying. This would seem especially the case when you’ve never been in an earthquake before.

What struck me at the time was the number of people who did not move from their movie seats.  A 12 year old knew something was up, but many just sat there. It was hard to see how people could have missed feeling the quake.

You wonder sometimes how folks can often be so oblivious to things taking place right in front of them. Whenever I see someone who seems clueless, I think back to that earthquake.

Below is information on that 1980 earthquake from the Ohio Seismic Network ( Click here for the full link.) — The earthquake that shook Ohio and all or portions of 13 other states and southern Canada on July 27, 1980, initiated numerous media and citizen inquiries concerning this particular earthquake and the general seismicity of Ohio. Many residents of Ohio were amazed to learn that the state had ever experienced any previous earthquakes and were startled to find out that more than 100 earthquakes have been reported from the state since 1776.
