Can you be sure that an earthquake could not occur in any area?

No, it is not possible to be completely sure that an earthquake could not occur in any area. Earthquakes are caused by the movement of tectonic plates, which can happen in a variety of locations, including those not typically associated with seismic activity. While some regions are more prone to earthquakes due to their geological makeup, it is always possible for unexpected seismic events to occur anywhere. Therefore, preparedness and awareness are essential, regardless of an area's historical seismic activity.
