Individual Event Report

Event #451 - Summary, and parameter estimates with source IDs
The BSSA is cited as a source for this earthquake: "A shock at Medford, Oregon. - A slight earthquake is reported from Medford, Oregon. It occurred at 12:40 p.m. March 15, 1913: no damage was done." The Medford 'Mail Tribune' is more verbose but in good general agreement with the BSSA,although a "Y" shaped pavement crack about ten feet long was said to have been caused by the earthquake. It describes the earthquake as lasting five seconds.

Transcription: An earthquake of five seconds duration, in two distinct shocks, was felt in Medford Saturday by Professor P.J. O' Gara and a score of others. The tremblor created no damage aside from the cracking of the pavement on a main street. The first shock was felt at 12:40 and was of two seconds duration. The second came fifteen seconds later and lasted for 3 seconds. As far as the weather department records show this is the first shock in the valley. The effects of the shock were most perceptibly felt in the Garnett- Corey building. The elevator man reported that the cage rocked and that the cable swung back and forth, as if a man was shaking it with his hands. In Dr Taylor's office in the same building dishes rattled and some dropped from the shelf to the floor. Mrs Phil Hammi was one of those who noticed the quake. Prof O'Gara was seated at his desk when the first shock came, and instinctively looked at his watch. His first impression was that the building had been struck by some heavy object. A few seconds later the second quake came. "The course of the quake seemed to be from the north to the south", said Prof O'Gara, "and was probably caused by a slippage of rock in the earth. The disturbance was secondary and the parent quake might have been in the middle of the Pacific Ocean. As far as I have been able to find the seismograph stations at San Francisco and Seattle failed to record any disturbance". Very few people knew that an earthquake had visited the city, and the crack in the pavement on East main street was a mystery. It is "Y" shaped and about ten feet long.
