Shattered Earth (aka Cloudy Mountain)

A peaceful town turns into a living hell when friction on the Indian Ocean plate triggers a devastating earthquake causing buildings to tumble and sinkholes to open. A retired railway soldier and his son, an explosive demolition engineer, go deep into a solution cave to rescue trapped survivors. But a second quake is due to follow in a few hours.... To save the whole town from being buried by landslide, the only way out is to blast the tunnel that they have built for 10 years.
