24:0 EARTHQUAKES ON THE PACIFIC COAST 



1895. May 21; San Jose-Mount Hamilton. 



[The telephone operator in San Jose reported a sho'jk of earthquake 

 in San Jose about 10.45 a. m. W. W. C. and JR. H. T. (at Mount 

 Hamilton) noticed rattling about that time, but felt nothing-. The 

 duplex instrument shows a slight mark, probably from this shock, 

 of 1 mm. (earth's movement 14 mm). — N. \V. Later it Avas learned 

 that the nitroglycerin works at Pinole, Contra Costa County, had 

 exploded at 10.40 on that morning. Doubtless the shock noted 

 above was due to this explosion. Pinole is nearly 60 miles in an 

 air line from Mount Hamilton.]

[A newspaper account from New Whatcom, Wash., says Mount 

 Baker (40 miles away) has been smoking or steaming, and that 

 a new peak has appeared between the dome and south peak, vis- 

 ible at New Whatcom with the naked eye. Note. — This report has 

 not been verified. — C. D. P.] 



1895. June 15; Port Townsend, Wash., Jnne 16. 



[Chimacum, a small farming center 4 miles from here, was terribly 

 shaken last night at 8 o'clock by the falling of a huge meteor, 

 which burst with a loud noise, and after causing a small-sized 

 cyclone of several minutes' duration, buried itself deep in the 

 muddy bottom of a neighboring lagoon. The meteor struck with 

 force enough to break crockery in farmhouses 3 miles away and 

 created great terror among the residents. Ten hours after the 

 occurrence the waters of the lagoon were stil] bubbling and seeth- 

 ing, and were found to be hot. Systematic dragging of the 

 lagoon failed to bring up any traces of the celestial messenger. — 

 S. F. Examiner, June 17, 1895.]

" One shock of intensity II or III, northeast and southwest, third- 

 story brick house." — C. D. P. The duplex instrument shows a 

 single displacement of the earth of about V2 mm. in a northeast 

 and southwest direction with several very small vibrations at 

 the end.
