Earthquake Spell

Earthquake Spells are powerful elemental spells used to trigger an earthquake.

History
When Arthur was about to be executed by Odin and Morgana, Merlin cast a spell to trigger an earthquake. Arthur and Percival defeated their captors in the resulting confusion and they, Merlin, Mithian, and Rodor escaped.

Effects
To cast this spell, Merlin chanted the incantation aloud, then struck the earth with his open palm to trigger the quake.

The full extent of the damage caused by this spell is unknown. The tomb began to shake and parts of the ceiling fell in, but the structure did not collapse. Interestingly, the quake seemed to be confined to the tomb itself and did not affect the area around it (Another's Sorrow).
