This powerful illusion forces the people caught in the area of effect to believe a powerful earthquake is ripping the earth apart. Any creature failing its Int save will be knocked down and see the surrounding creatures and structures do the same. The effect lasts one round, during which any creature caught in the illusion can't move or attack. The specific effect of the illusion depends on the nature of the terrain where it is used.

• Cave, Cavern, or Tunnel: The technique collapses the roof, dealing 80 points of nonlethal damage to any creature caught under the cave-in (Dex DC 15 half) and pinning that creature beneath the rubble (see below). Creatures disbelieving this illusion are unaffected.
  
• Cliffs: Earthquake causes a cliff to crumble, creating a landslide that travels horizontally as far as it fell vertically. Any creature in the path takes 80 points of nonlethal damage (Reflex DC 15 half) and is pinned beneath the rubble (see below).
  
• Open Ground: Each creature standing in the area must make a DC 15 Dex save or fall down. Fissures open in the earth, and every creature on the ground has a 25% chance to fall into one (Dex DC 20 to avoid a fissure). At the end of the technique, all fissures grind shut, causing any creature "falling" in them 90 points of nonlethal damage.
  
• Pinned beneath Rubble: Any creature pinned beneath rubble takes 70 points of nonlethal damage and be unable to move or perform hand seals.

After the illusion fades, every creature within the area that fell for the technique will realize that nothing happened. The user is unaffected by his own illusion.
