ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 293 
(D. Stirling.)—In the Pajaro Valley, on the McGowan ranch, at a bend of the river, 
an acre or more of orchard has sunk about 2 feet. At Moss Landing, where the river runs 
parallel with the shore line, the strip of land is seamed for miles. A crack, or rather a 
sink, about 20 feet wide and 4 or 5 feet deep ran under the buildings and rent them 
asunder. The office building between this crack and the river has been moved 
bodily — land and all — about 12 feet toward the river. Some of the cracks run into 
the ocean. At Neponset and Salinas the piling under the county bridges was moved in 
some of the bents at least 10 feet toward the river. A section man who stood in the midst 
of the cracks at the end of the Neponset bridge was drenched with spurting water. 

SALINAS TO SAN LUIS OBISPO AND WESTWARD. 
Effect of the Shock on Alluvium (G. A. Waring). — Altho the Salinas river bed sank 
nearly 6 feet at King City, and the wide sandy bottom at Three Mile Flat was much 
cracked, the southernmost extension of continuous cracks along the bank was found to 
be about 2.5 miles south of Gonzales bridge. From here to the mouth of the river the 
cracks are parallel with the river banks. 
The movement at Gonzales bridge was mostly on the west bank of the stream. A wire 
fence trending north and south was torn 6 inches apart here, and wooden piles at the 
southwest end of the bridge, said to be driven down 75 feet, have been torn loose and 
moved from plumb, their original upright position. At the northeast end of the bridge 
the piles are undisturbed, but the surface soil and a wire fence have moved relatively 
18 inches northward. (See fig. 59.) 
North of Gonzales bridge the fissures are mostly on the west side of the stream channel, 
and reach a maximum width of 18 inches. No evidence of shearing could be found. In 
the creek bottoms west of Chualar, sand craterlets begin to appear and become numerous 
along the stream northward. 
Near Agenda, in the lowlands, is a cracked area nearly a mile from the river, probably 
along an old water course; while sand craterlets are scattered thru the orchards. At 
Spreckels the movement caused much damage to flumes, sewers, and water-mains; and 
from here to Blanco the deep soil of the adjacent fields is much cracked and in places 
sunken and dotted with sand craterlets. 
The county bridge south of Salinas was rendered unsafe by the movement of the piers 
at the southern end. (Plate 123.) On the west bank near the bridge a series of peculiar 
eracks have torn up the road and adjacent field, along what is probably the path of an old 
water course. These are shown in plates 136, 137. ; 
Between Blanco and Neponset the cracking and settling of the low land flooded the 
adjacent fields and gave rise to stories about the Salinas River having risen several 
feet. The “boiling up” of the water thru sand craterlets was also soon distorted into a 
story about the water of the Salinas River being boiling hot. Both the railway and 
county bridges at Neponset were moved, the northern concrete piers of the former 2 
inches east and the central wooden pier of the latter apparently 4 feet south. 
From Morocoho to Moss Landing fissures rarely show in marshy land, but the narrow- 
gage railway track has been shifted a few inches in several places. At Moss Landing 
many small cracks occur in the mud on the west side of the river, and the condition of 
the wharf indicates an eastward movement of the sand-spit. (See plates 1348, 135A, B.) 
It is reported that at places along the pier where the water was formerly 6 feet deep, it 
now has a depth of 18 or 20 feet. North of Moss Landing the ground settled nearly 2 
feet in places, as shown by marks on railway piles at several slough crossings and by the 
sagging of the track below grade line in several other places. The stretch of narrow-gage 
track parallel to the coast has been disturbed for nearly its whole length; in some places 
it is wavy, in others the entire roadbed has shifted. At one point about 5 miles south of
