The biggest fault line of all is measured up to 5,500 km and is found at South East Asia. It is located from Myanmar and runs all around the nearby regions until it reaches Australia. The movement of this fault line resulted in the 2004 India Earthquake that led to a tsunami claiming at least 230,000 lives.
This has been the list of 11 biggest fault lines in the world. If you want to stay away from dangerous earthquakes, then do not live near these fault lines.
