The Beam-Quake that hits Gilead

A Beam-Quake is the destructive event that happens when one of the six Beams that holds up the Dark Tower is destroyed.

They leave giant fissures across the landscape, destroying anything that lies along its destructive path. The fallen city of Gilead which sat along the Eagle-Lion Beam is partially destroyed when the Beam breaks.

Another Beam-Quake is seen during the events of Song of Susannah, due to the destructive work of the Breakers.

in The Wolves of the Calla the Bear-Turtle beam cracks, causing an earthquake that Roland and his tet feel when they're palavering with father Callahan.
