That still doesn't explain as to how such (relatively) small monster could cause such huge quakes. You did however pretty much sum up the total IQ of all of Moga Village into a number less than 200.

If the Ceadus actually wasn't the cause of the earthquakes, then wthat could it have been (besides natural tectonic plate movement)?
