The San Francisco earthquake of 1906 badly frightened the guests, but did no structural damage to the hotel. John Farish, a mining engineer staying at the hotel, described the experience: "I was awakened by a loud rumbling noise which could be compared to the mixed sound of a strong wind rushing through a forest and the breaking of waves against a cliff...there began a series of the liveliest motions imagineable, accompanied by a creaking, grinding, rasping sound, followed by tremendous crashes as the cornices of adjoining buildings and chimneys tottered to the ground."
