Damage
Damage in Olympia from the earthquake was estimated between $500,000 and $1 million by Governor Arthur B. Langlie.[5] Eight buildings on the State Capital campus were damaged by the earthquake, as well as the Old Capitol Building in downtown Olympia.[6] A 23-ton cradle on the east tower of the Tacoma Narrows Bridge fell 500 feet (150 m), injuring two men. The earthquake caused geysers to explode along the railroad track in the Tacoma tidal flats and in Puyallup.
In Seattle, nearly every building in the Pioneer Square neighborhood was affected in some way, with damage ranging from lost parapets to entire floors and in some cases entire buildings needing to be demolished over the following years. Most buildings still show the scars of earthquake damage and the mostly hasty repairs made to them.[citation needed]
Chimneys throughout western Washington collapsed.[7] Severe damage were recorded at schools in Adna and Napavine, and structural losses to buildings in Centralia's downtown district. The earthquake caused catastrophic loss to two schools in Chehalis, a state training school for youths and West Side Elementary; neither were rebuilt.[8][9]
Eight people were killed, including young crossing guard Marvin Klegman who shielded a second-grader from falling bricks.[7] At least 64 people were injured, and the total damage is estimated at $25 million.
