Individual Event Report
Event #112 - Summary, and parameter estimates with source IDs                                           
Known only from the handwritten report of the weather obeserver at Eola, Polk County, who said: "A slight shock of an earthquake felt in Salem". However, this report gives coordinates of 'Latitude - 44 degrees, 5", Longitude - 123 degrees, 5"', which would place it in present-day Lane County, not Polk. We do not know the location of Eola
