Did you know the Richter scale goes over 10 and it goes in the negative levels too? Me neither. Or you probably did if you work in the domain. This is a short presentation of the Richter scale, including negative levels. I found this information from Randall Munroe's book "What if?" (the XKCD author) combined with Wikipedia. I thought I'd share because I found it really interesting. Also added my own personal touch.
All credits go to their respective authors.
A speck of dust landing on a table.
A speck of sand falling in a hourglass.
A feather landing on the ground.
Someone pressing a key on a laptop keyboard. Laptop users (myself included) are making a -7 quake each time they type.
A key press on a normal keyboard. Probably for the mechanical keyboard uses it's more.
A penny falling from a dog. Why? Don't know.
An object falling from a nightstand.
A cat falling off from a dresser. Ouch.
A football player running into a tree in your yard. Why would he do that in the first place?
A professional football team running into the side of your neighbor's garage. We should stop questioning why.
Micro earthquakes, not felt, or felt rarely. Recorded by seismographs.
Felt slightly by some people. No damage to buildings.
Often felt by people, but very rarely causes damage. Shaking of indoor objects can be noticeable.
Noticeable shaking of indoor objects and rattling noises. Felt by most people in the affected area. Slightly felt outside.
Can cause damage of varying severity to poorly constructed buildings. Zero to slight damage to all other buildings. Felt by everyone.
Damage to a moderate number of well-built structures in populated areas. Earthquake-resistant structures survive with slight to moderate damage. Poorly designed structures receive moderate to severe damage.
Causes damage to most buildings, some to partially or completely collapse or receive severe damage. Well-designed structures are likely to receive damage. Felt across great distances with major damage mostly limited to 250 km from epicenter.
Major damage to buildings, structures likely to be destroyed. Will cause moderate to heavy damage to sturdy or earthquake-resistant buildings. Damaging in large areas. Felt in extremely large regions.
At or near total destruction – severe damage or collapse to all buildings. Heavy damage and shaking extends to distant locations. Permanent changes in ground topography.
The earthquake caused by the Death Star on Alderaan. In a nutshell: total death.
The Sun could have a magnitude 20 earthquake, although it'd trigger a supernova. It's about the energy release if you packed the earth with hydrogen bombs and detonated all of them at once. Not the best thing to imagine.
I personally found all of this interesting, there are other such odd facts in Munroe's book, definitely enjoyed the read.
