What is the largest earthquake that can possibly happen on Earth? A magnitude 10? Magnitude 11? Today's video will in the first 30 seconds answer this question and give a detailed explanation on where exactly such an earthquake could theoretically happen. This all is being narrated through the knowledge and opinion of a geologist. Estimates on asteroid diameter, velocity, tnt energy equivalent, initial crater depth, and effects from the impact (including earthquake magnitude generated and wind speeds generated) in this video were sourced using the calculator at https://impact.ese.ic.ac.uk/ImpactEarth/ImpactEffects/, which was used with permission.
