Please note that the following earthquakes will be categorized based on their Richter Scale "score".
These Earthquakes occur daily; they are so light, however, that we don't ever notice them. Earthquakes of magnitude 0-1.99 can only be detected by seismographs. An earthquake of 2-2.99 magnitude could be felt by a normal person, but they would have to be close to the epicenter. An M2 earthquake could set hanging things into motion.
One example of an earthquake of this category is one that occurred 90km SSE of Emajuaga, Puerto Rico.
Due to the fact that it occurred in the middle of the sea, it didn't cause any damage. Even if it had been on the island, Puerto Rico would have survived the earthquake unscathed.
PS: That's why I'm not including any pictures for the "damage".
The vibrations are very noticeable this time, but they don't cause much damage. These also occur daily.
Those that are 3-3.99 will create vibrations "comparable to the vibrations of a passing truck". They will be felt, but will have no effect.
Earthquakes of magnitude 4-4.99 will be stronger, but still subtle. They will have consequences, however. They will cause any small or loose/unstable objects to fall. Think of cups and plates rattling and falling of off counter tops.
A recent example of this type of quake happened around 1 or 2 pm, the 2nd of October. It was located about 7-8 km SE of Harper, Kansas.
It has only rattled the citizens and put them "on the edge". I'm not sure of what, if any, physical damage it caused. There weren't too many news reports on this event. Thus, I can't procure an image about the damage it's done.
These earthquakes can do some good amount of damage. They occur around every month or so.
Earthquakes rated 5-5.99 have enough power to move furniture. They can also make loose parts of the house (plaster, shingles, etc.) fall off. Those rated 6-6.99 are stronger, and can cause significant damage to houses. The amount of damage a house receives depends on how well it's built.
An earthquake of this kind struck Weiyuan, China two days ago. To be specific, it was a magnitude 6.0.
It caused major destruction of homes, forcing many to camp outside. 8 aftershocks soon followed, the strongest of which was M4.2. At least one person has been killed. A nearby dam had cracked, and so the area around it had been evacuated. Repairs for all of the homes and the dam are currently underway.
These quakes are serious. They can tear buildings from their foundations and create cracks in the earth itself. Any structures stuck in a bad spot will probably be destroyed. Thus, almost-total destruction ensues.
They can occur on either a monthly or yearly schedule.
A magnitude 7.9 earthquake hit Kanto, Japan in 1923. At the time, it was the worst earthquake ever to hit Japan. It only lasted 14 seconds, but that was plenty of time for the quake to wreak havoc. The quake created a 40 foot tsunami, which was soon followed by fires galore. The ground became a liquid and sucked in many buildings (and possibly people). In the end, the death toll reached 140,000.
This earthquake was significantly important because of two effects. It practically destroyed Japan's two biggest cities, Yokohama and Tokyo. Also, it greatly affected Japan's stance in world affairs, which would later influence their decisions during WWII.
These earthquakes are extremely destructive, almost unbelievably so. They're so strong that someone can see waves "flowing" through the earth with their naked eye. There won't be much left afterwards; most structures will be in pieces. Luckily, though, these are only an annual occurrence.
Earthquakes with a rating over 10 are unheard of, and are technically impossible. There are debates as to what would happen if one did occur, but it's uncertain.
In 1960, an M9.5 earthquake hit Chile. Currently, it is the world's largest earthquake to have ever occurred.
More than 2,000 were killed in southern Chile, and the resulting tsunamis killed about 200 people in Hawaii, Japan, and Philippines. The coasts of the US and Australia were also affected.
This main earthquake was a part of a bundle of many other earthquakes that occurred within the same hour. It caused massive flooding, plenty of tsunamis, and even the eruption of a volcano. The volcano, however, erupted two days afterwards.
