There are a range of apps and programs that monitor global earthquake activity, and you can get access to these on your Android, iOS, or home PC. Social media plays a huge role alerting people about earthquakes & tsunamis in their area, but there are so many earthquakes worldwide that sensors, and control centres are set up all over the planet to measure this seismic activity. Each of these centres communicates their data with each other, and they share it publicly too. There are a number of programmers and developers who have built apps that read this information, and allow you to get alerts of the tsunamis and earthquakes as they happen. Although not every earthquake is life threatening, its handy to have these apps installed on your pc or mobile phone, just incase you have to take action with a large one, such as the recent Nepal earthquake.
