The weakest earthquake recorded is usually referred to as a microearthquake, which typically has a magnitude below 2.0 on the Richter scale. These earthquakes are often not felt by humans and are mainly detected by seismographs.
Somewhere in the 3.0 to 4.0 magnitude range, depending on the geology and, of course, how close you are to the epicenter.
The weakest earthquake ever recorded was in 1962 and it was approximately 0.001643 on the Richter scale. Hope that answers your question Peter I. Staker, National Geographic Seismologist

I think it was New York but I am not totally 100% sure.
You can't actually SEE an earthquake. You can feel it. The feeling of it and the destruction all depends on the magnitude (power) of the earthquake. Seismologists (people who study earthquakes) rate it on a scale from 1-10. 1 is the weakest; you can barely feel anything. 10 can cause buildings to crumble in the blink of an eye. 10 can kill many people and cause many issues for the area that gets hit with this. Take the Japan incident for example. The latest results say that it was an 8.9 magnitude. It caused one of the worst tsunamis in history and destroyed most of Japan.
Well, the weakest earthquakes form at divergent boundaries, therefore, weaker earthquakes form where plates pull apart from each other
Great earthquakes: magnitude 8.0 or higher, capable of causing widespread and severe damage. Major earthquakes: magnitude 7.0-7.9, significant damage likely in populated areas. Strong earthquakes: magnitude 6.0-6.9, can cause damage to buildings in populated areas. Moderate earthquakes: magnitude 5.0-5.9, minor to moderate damage possible, felt by people.
with a tornado, the damage it causes is used to estimated wind speed and assign a rating on the Enhanced Fujita scale (which replaced the Fujita scale), which runs from EF0 for the weakest tornadoes to EF5 for the strongest. With an earthquake, seismometers measure ground vibrations at different distances. This is used to estimate intensity and rate it on the Moment Magnitude scale (which replaced the Richter scale), which has no real upper or lower bounds, but is generally considered to run from magnitude 1.0 to magnitude 10.0
The moment magnitude scale goes as low as 0.0 and any quake that released less than 63 kilojoules of energy would registrer as 0.0 on the Richter scale. Quakes with a Richter value of 2.0 or less were classified as "microquakes" and were almost never detected by human senses.
Hard to answer because there are extremely small earthquakes going on everywhere around the world.
The weakest wind ever recorded was 0.5 miles per hour (0.2 meters per second). This extremely calm wind speed was measured in several locations around the world during times of unusual atmospheric conditions.
