ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 201 
and Main Streets) and stood in the street between the Grand Hotel and the court-house. 
He states that he saw the dome swinging southeast and northwest, tho later in describing 
the motion he added that it was swinging up and down Third Street, which runs south of 
west and north of east. “ With the last swing the ground came up short and stopt,” and 
then the building fell. “All the buildings fell at once; no one first.’”’ The dome of the 
court-house fell east. Down Fourth Street the dust was so great that he could see nothing. 
He is sure that he heard but one crash. 
In general, inquiries as to direction of fall of buildings met no definite answer, or else the 
answer was very definite with no indication of good observational basis. Many told me 
that there was no direction of fall; that the buildings simply crumbled to the ground. 
The Masonic Temple and the Theater, I was told, fell so directly downward “that the 
débris did not extend beyond the walls 10 feet in any direction.” This was substantially 
my observation on passing thru the ruined district on May 1. 
Mr. M. W. Keithby, the watchman at the tannery, F and Second Streets, says that the 
liquor in the vats was thrown straight up and then splashed out on all sides. The tanks 
tipt to the west. A 3-story frame shoe factory on the north side of the tannery grounds 
went completely down — being flattened with but little direction of fall. One of the fore- 
men said that the fall was slightly to the north and that heavy machinery was found close 
to the north wall on the third floor. 
A teamster working in the creek just south of the tannery says that he noticed cracks an 
inch wide and several rods long a few days after the shock. He “thinks the cracks were not 
there before.” 
Mr. Searey, a teacher in the High School, stated that the vibration was east and west. 
In describing the shock, he stated that in coming thru a doorway facing west, he was 
thrown against the north casing. 
A rather large 1-story frame building on Eighth Street with a brick and stone founda- 
tion was shifted N. 3° W. On A Street, near Fifth, a cottage fell to the south. The 
house at Johnson and Mendocino Streets fell to the north, while of the two houses at Men- 
docino and College Streets, one fell southeast and the other north. On Fourth Street, 
near E, a residence fell to the east. On MacDonald Avenue, Mr. Weaver found two houses 
that fell to the north. The lack of harmony in the direction of fall, and the short time, pre- 
vented an investigation of the direction of fall of all the residences wrecked. 
The main Santa Rosa Cemetery, just beyond the city limits on the northeast, was badly 
wrecked, but not to such a degree as the cemetery at Sebastopol. The direction of fall of 
monuments was carefully noted, but no indication of regularity resulted. Of square 
monuments of approximately equal size and conditions, 12 fell north, 10 south, 7 east, and 
13 west. (See plate 80a, B.) 
The most marked physiographic effects in the vicinity of Santa Rosa were found near 
this cemetery. Just north of the cemetery hill is a swampy depression. Part of this 
settled 2 or 3 feet with the formation of a crack along the side, extending for some 200 feet. 
The cemetery is on a low hill which the sexton reports as being sand, gravel, and clay, but 
which shows a rocky outcrop, on the eastern side, near the base. A crack an inch or more 
wide was found on the northern end of the hill near the swamp mentioned above. This 
crack could not be followed for more than 100 feet, altho the sexton reports that at first it 
extended 2 or 3 times that distance. A small water-pipe on the southern part of the hill, 
running north and south, was pulled apart. A pipe on the northern part of the hill, run- 
ning east and west, is reported by Mr. Weaver as pulled apart about 4inches. On the south- 
west of the cemetery hill, Mr. John Livsey reports that several fine cracks formed across 
the road running north and south, and that the dust was blown away near the edges of the 
tracks. He also reports that the trees along the road were swinging very definitely in line 
with the road, which here runs northwest. The only other physiographic effects found were 
at the County Hospital, a little more than a mile north of the cemetery. Here low ground 
at the foot of a small hill sank for some 2 feet and springs were formed. These springs were 
reported as still running the last of July. No connection could be found between the dis- 
turbances at the cemetery and the hospital. In the cemetery a large tank fell to the north. 
The tank was close to the water-pipe that was pulled apart on the north and south line. 
At the Catholic Cemetery, some 2 miles southeast of Santa Rosa, only one monument 
fell out of some 20 of the class that were commonly overthrown at the main cemetery. 
Going farther southeast thru Bennett Valley, no physiographic effects were discovered 
and few chimneys were thrown down. 
Not knowing of Mr. Butler’s trip to the southward, I duplicated part of his work to the 
south of Santa Rosa, on the Petaluma road, with the same results as stated in his report.
