Since the strongest earthquake in the history shook the Western Coast of America, a seismologist named Samantha Hill takes her country through the most horrible natural disasters. Working with a geologist Jordan, Samantha becomes a symbol of courage and durability. However, when tsunami wipes Waikiki off the face of the earth, her apprehensions about the consequences of earthquakes come true. The areas which were seismically quiet for many centuries become awake now. A ski resort vanishes in a deathly cloud of smoke and ashes, boiling water comes out of the earth and floods a valley, the Guver dam breaks and frees the water floods of a great destructive power; and the Rashmore Mountain explodes in the hell of melted lava.
