San Jose Tribune, January 14, 1857:

"At about four o'clock on Friday morning last, Jan. 9th., a pretty severe shock of an earthquake was felt in this city, and a still stronger one on the same morning at about half past eight. The vibrations were from East to West, and continued for the space of nearly if not quite, a minute. The San Francisco papers state that the shock was felt there at a few minutes after 8 o'clock; and a telegraphic dispatch from Sacramento announced that it came off in that city between 7 and 8. If such was the relative time of the occurrence of the phenomenon, we would request our friends in Sacramento on the next repetition of the performance, to send us a telegraphic dispatch forthwith; which will enable us all in this section of the State to be prepared for the catastrophe. Those of us particularly who dwell in houses of brick or adobe, would much prefer to step out on such occasions into the street, and there quietly wait for the wagging, rather than to be surprised within four trembling walls of untried solidity, and compelled either to watch suspiciously the vibrations, and calculate our chances of being buried beneath the ruins of our own domiciles, or else to compromise our dignity by rushing incontinently forth into the open air."
