East coast buildings have no resistance to earthquakes. Therefore, aftershocks take place immediately after a strong earthquake can cause damage here. The earthquake on March 23 made Washington's iconic tower - Washington Memorial - cracked. US officials announced to close the building indefinitely. Meanwhile, the top of the National Cathedral cathedral is headless.

Many schools and buildings throughout the area were also slightly damaged.
