What to do after an earthquake aftershocks hours, days, or weeks after the main quake?
Aftershocks can cause building damage and falling remains that could hurt you .Make sure that you avoid open flames in defective buildings. Earthquakes can bust gas lines, so don’t use lighters or matches. Earthquakes can cause dangerous tsunamis and flooding so if you live near the coast, stay away from the beach. Drive carefully and plan alternative routes. Structural damage and traffic light outages may make it difficult to get to your destination.
