COMPARISON WITH OTHER SEVERE EARTHQUAKES IN SAME REGION, 443 
The shock was from southwest to northeast. The ground opened from 6 inches to 
2 feet, and water with sand was ejected to a height of from 1 to 3 feet. North of the 
village a ridge of ground 3 feet wide was raised 2 feet. By the time the shock was over, 
nearly the whole place was in ruins. Near Hayward’s Hotel the hill shifted a good deal, 
and a crack opened for several hundred feet. On the hills there were several new springs. 
In the first 12 hours after the main shock there were 36 after-shocks. Between Hay- 
wards and Mission San Jose there were numerous cracks, so that it was difficult to drive 
a stage between the two towns. (Alta California, Oct. 22-25, 1868.) 
Mt. Eden. — All the shelving on south side of the 2 stores of the town was thrown 
down. (Alta California, Oct. 22, 1868.) 
Alvarado. — Shocks were violent. The ground opened in several places and water 
issued. (Alta California, Oct. 22. 1868.) 
Centerville. — A dwelling-house was partly destroyed and 2 stores were wrecked. 
Hotel settled 2 feet. (Alta California, Oct. 22, 1868.) 
Roberts’ Landing.—“ Our house broke in three pieces, each part falling outward. <A 
boiler of hot water was on the stove, and with the first deafening jolt, the hot water 
came my way, giving me a bath I have never forgotten. Horses fell to the ground and 
men clung to some quince trees near. 
“Captain Petersen, of the steamer San Lorenzo, who is now deceased, was walking 
along the road to Roberts’ Landing when he heard a great rumble off across the fields 
toward San Leandro. He lookt quickly in that direction, and over a mile away could 
see the great wave rapidly approaching. He rushed to the side of the road and had 
caught hold of the fence by the time the shock broke. Near him on the road a 6-mule 
team was drawing a load of grain, and all the mules fell flat and could not regain their 
feet until the great jolt was over. During the 3 or 4 succeeding days there were 150 
shocks; none, of course, with anywhere near the extent of the heavy one.”’ (R. C. Vose.) 
Decoto. — Opposite Decoto a crack appeared about one-third of the way up the slope. 
It opened 10 or 12 inches at the surface and faulted about as much on the plains side. 
The level lands waved like the ocean, and the waves seemed to approach from the south. 
(Mr. Decoto.) 
Tyson Lagoon, south of Niles. — A tank swayed north, then south, and fell. The 
lagoon parted lengthwise down the middle and threw water and mud both ways. After 
the earthquake the lagoon was dry for 3 years. It has no outlet. Rumblings preceded 
the main shock and many of the after-shocks. (Mrs. Wm. Tyson.) 
A crack went thru the old Shinn place, crost the Centerville-Niles road about 0.6 
mile southwest of the Southern Pacific Railway track, and past thru the Tyson Lagoon. 
(H. Tyson.) 
Niles. —The water from the tank slopt nearly east. Rumblings preceded the after- 
shocks. These were more severe than in April, 1906. (C. Overacher.) 
A crack past thru the Shinn and Tyson places. (C. Bonner.) { 
Irvington. — Thru the north side of town a erack split the hillside, opening 7 or 8 
inches and showing a fault of 8 or 10 inches. It crost the country road 500 feet north 
of the Southern Pacific Railway depot. Its trend was N. 45° to 50° W. From these 
low hills the crack seemed to pass over into the tule ponds north of town. The Tyson 
Lagoon dried up after the quake. The rumbling preceding the shock came from the 
north. (R. B. Crowell.) 
The railroad tracks north of the station were badly twisted for several hundred yards. 
(M. Torry.) 
In one place the crack on the hillside divided, and formed a narrow island, 8 or 10 
feet across, which dropt below the general level of the sod 8 or 10 inches. Springs were 
opened up on Mission Peak. (H. Crowell.) The crack which past thru the town con-
