Video recorded inside the Washington Monument shows the earthquake shaking its structure and people running down the stairs as debris falls from the ceiling.
The National Park Service released video on Monday (September 26) from three security cameras mounted inside the monument 500 feet above ground level.
The video shows the monument's walls shaking as the earthquake hits, chunks of stone falling from the ceilings and tourists rushing to evacuate through a stairwell.
The 5.8 magnitude earthquake that shook much of the East Coast in August cracked stones near the top of the Washington Monument.
The Washington monument remains closed to the public until further notice as the National Park Service continues inspecting the earthquake damage.
