I wanted to share a picture with you of China's Three Gorges Dam. This is the dam they are concerned with in regard to earthquakes and have installed alarms. It is understandable the country of China would want to monitor this dam and it's potenitally dangerous impact if something unexpected happens. The Three Gorges Dam is so huge it shows up on satellites impacting on the water flow even to the ocean. It has and is developing it's own ecosystem. It provides a huge amount of water to the people of China.
