# Earthquakes With Magnitudes of 1.0-2.99

Earthquakes with magnitudes of 1-2.99 are very minor earthquakes that cause little damage. Earthquakes like these happen daily and are mainly just the ground vibrating, and not many cracks in the ground are formed.

Earthquake near Cave City, Arkansas

The earthquake that I selected was 7 km NW of Cave City, Arkansas. It was a 2.5 magnitude and occurred 9:09 AM on October 8th, 2014. This earthquake had a depth of 10.7 km. I do not know what kind of damage was caused because it was so minor. There is not enough information on this earthquake, because it was so minor, to know what the aftereffects were.

# Earthquakes With Magnitudes of 3.0-4.99

Earthquakes with magnitudes of 3-4.99 are still small earthquakes, but are not as minor as 1-2.99 earthquakes are. Earthquakes with magnitudes of 3-4.99 occur daily but cause a little more damage. The movement is small to moderate. There may be small structural damage but probably nothing more that some shingles falling off of the roof.

4.2 magnitude earthquake in China

There are no pictures of this earthquake in China because it is still a minor one. The damage was minor but was worse than one with a smaller magnitude. The aftereffects were small considering that it was a minor earthquake.

# Earthquakes With Magnitudes of 5-6.99

Earthquakes with magnitudes from 5-6.99 are moderate earthquakes that occur monthly. They can cause a moderate amount of damage. An earthquake like this can cause all of the items in a store on shelves to fall. The movement of these earthquakes are strong and sudden. These kinds of earthquakes are usually broadcast on local news, unless it occurred in a highly populated area.

The earthquake I chose for this range of magnitudes was the earthquake in San Francisco on October 30, 2007. This earthquake had a magnitude of 5.6. The damage was mainly items falling off of the shelves. The aftereffects were that some stores had to close because of the earthquake.

# Earthquakes With Magnitudes of 7-8.99

Earthquakes with magnitudes from 7-8.99 are major earthquakes that occur 1-2 times a year. These earthquakes cause moderate to major structural damage. These earthquakes are broadcast nationally, because they are so strong.

The earthquake that I chose for this range of magnitudes is the San Francisco earthquake of 1906. This earthquake is very famous and had a magnitude of 7.8. The damage it caused was very major, as you can tell in the picture. The aftereffects were terrible, because many buildings crumbed and fell.

# Earthquakes With Magnitudes of 9+

Earthquakes with magnitudes of 9+ are very major and very severe. These earthquakes are very rare and only occur 1 time every 10 years. These earthquakes are broadcast internationally because they are so major. These earthquakes have extreme and sudden movement.

The earthquake that I chose was the 1964 Alaska earthquake. It had a magnitude of 9.2. It almost completely destroyed roads, therefore you couldn't drive anywhere.
