Satellite technology can provide near-immediate warning of earthquakes that may trigger tsunamis. The warning time depends on the distance of the epicenter from the coastline. Notifications are sent to coastal communities predicting arrival times of tsunamis that could reach them within hours. It is important to know your home's location relative to the coast and sea level, have evacuation routes planned with your family, and practice those routes before a disaster occurs. Creating a family disaster plan designating meeting places and emergency contacts can help reunite family members should they become separated during an evacuation.
