Individual Event Report
Event #72 - Summary, and parameter estimates with source IDs                                           
There has been some confusion as to the date of this event. Newspaper accounts place the date on May 20, and describe the earthquake as a "smart shock" in Mukilteo and also felt in Tulalip. Holden (1887) gives a date of May 30. Holden cites an account in the San Francisco Bulletin and calls this event "severe". Other catalogs stem from Holden. Rasmussen lists what is probably this event with an apparently erroneous date of June 20.
