In an earthquake-prone area, it has been many years since the last earthquake along a fault. should residents be concerned about a future earthquake? explain.

Yes, residents living in an earthquake-prone area should be concerned about a future earthquake, even if the last earthquake had been many years before. Remember, an earthquake-prone area is an area that has frequent earthquakes (earthquakes that happen all the time). So, even if an earthquake hasn't happened in a few years, it doesn't mean that it won't happen again. If you live in an earthquake-prone area, make sure to always have emergency supplies with you at all times, and in case of a major earthquake, stay with an adult, and make sure that you have water and food.

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.
