Individual Event Report
 
| Event #400 - Summary, and parameter estimates with source IDs                                             | 
 
| This event is represented in most catalogs, but no magnitude has been assigned  to it. The handwritten weather records from Port Townsend say "1907 July    28     2:20 AM       Earthquake  quite heavy."  Milne cites the British Colonist, and says that many persons in Victoria and Port Townsend were wakened.  Townley and Allen found similar information in the San Francisco Chronicle. One of the accounts from Reid's scrapbook is garbled, and appears to be a mixture of this event and that of Jan. 11, 1909.  Newspaper accounts should probably be researched. |
