Hello Carol, See if you can locate a copy of California Earthquake of April
18, 1906 published by Carnege Institution of Washington 1908 reprinted in
1969. This is the reprint of the report of the California State earthquake
Investigation commission with Chariman Andrew C. Lawson providing an account
of the earthquake. It includes 13 pictures of the damage in the Santa Rosa
area with remarks. For example, (Page-199) Santa Rosa-- Prof. R.S. Holway
made a study of the effects of the earthquake at Santa Rosa and the
surrounding territory. According to the text, Sanata Rosa had the most
extensive damage of any city in the earthquake and was only second to
Sebastopol (where the Burbank farm was located). In the event you cannot
locate the report, I have included the text below.
----------------------------------------------------------------
To your question:
>Burbank we have a form with the above title which appears to
>be something that was given to citizens asking them to be observers
>of quakes, to record the data on the form, and it also has a list
>of earthquake intensities (Adapted Rossi-Forel)
The California Earthquake Report contains a record of after-shocks. What you
have may be one of the data collection sheets used to obtain consistent data
(I'm guessing her)that may have been sent out in one of the three circulars
mentioned below. The tables in the report contain the following headings, do
they match to what you are looking at?
Record of after-shock includes: Day, Beginning of shock, Duration,
Intensity, Locality, Remarks
Here is the text that goes with the tables. (Page 410)
"The list of after-shocks given below has been compiled by A. 0. Lcuschner
from all reports that have come to hand. These reports include not only
communications in answer to the three circulars sent out, but also other
reports by interested observers. In addition many shocks in the list were
taken from the separate reports printed in this volume. For the sake of
completeness the shocks reported by Prof. Alex. McAdie in his monthly
reports of the California Section of the Climatological Service of the
AVeather Bureau have also been included. A number of shocks have been
inserted in the first proof from Prof. Alex. MeAdie's Catalogue of
Earthquakes on the Pacific Coast 1897-1906.1 It should be stated, however,
that this list by no means represents a complete enumeration of all
after-shocks felt in California since April 18. In general, it may be said
that the list becomes increasingly incomplete with the lapse of time since
the great earthquake. This is particularly due to the efforts made by some
of the newspapers to suppress all news regarding earthquakes in California.
The list may be considered complete only for Berkeley, California, where
several observers have endeavored to record every shock. As a rule the
observer's name is included in the last column, initials being used for
observers who have reported more than one shock. A key to the initials is
given at the end of the list. The times are expressed in Pacific Standard
Time."

Report Data about Santa Rosa and the Burbank Farm.
The following is taken directly from the text (Page-205)
"Mr. G. K. Gilbert also visited the Burbank farm at Sebastopol, and
contributes the following note referring in part to the cracks discust by
President Jordan:
Mr. Luther Burbank gave me an account of personal experiences and of various
phenomena at Santa Rosa, and I record such items as are supplementary to
Professor Holway's report. Mr. Burbank was awake at the time. He immediately
got out of bed, but found he could not stand, and settled back against the
bed, holding on to the window casing and bedpost. The initial impulse was
from the west, and during the first portion of the earthquake the motion was
oscillatory, east and west. Then it became oscillatory north and south, and
at the close there was a complex motion which he compared with that of a
vessel in a choppy sea. From the window he saw trees waving, and after the
tremor had ceased he seemed to see a continued disturbance in the foot-hills
at the east, as tho the tremor was retreating in that direction. He said
that practically every one in Santa Rosa who was on foot at the time was
thrown to the ground, but that men on bicycles were not upset. During more
than 30 years' residence in Santa Rosa he had felt about 130 earthquakes.
None were comparable in violence with the recent one, tho several had broken
chimneys. A number of earthquakes which were felt generally in Santa Rosa
had not been felt at all in Sebastopol, and he thought that Santa Rosa was
peculiarly subject to shocks.
A shock was felt in Santa Rosa on April 17, 1906.
Mr. Lawrence, foreman on Mr. Burbank's farm at Sebastopol, stated that men
standing or walking at the time of the shock were thrown from their feet, as
were cows and horses. The small house on the Burbank place was moved from
its foundations a fewr inches downhill, and Mr. Lawrence mentioned a number
of houses which had moved various distances, the direction in every case
being downhill. On the Burbank farm a small landslide occurred, a layer of
moist soil only a few feet in thickness moving down the slope, introducing
bends in various lines of cultivated plants. I saw another feature of this
sort on an adjacent farm, and was told of others which I did not visit.
In a general note on the intensity of the earthquake, appended to detailed
observations which have been incorporated in the foregoing account of the
distribution of intensity, Mr. G. K. Gilbert says:
In general the violence seems to have been less in Petaluma than in
Sebastopol, Santa Rosa, or Maacama, notwithstanding the fact that it is
nearer the main fault. As compared with Sebastopol and Santa Rosa, however,
Petaluma seems to be on relatively firm ground, excepting a small district
bordering the marshes. In a general way, I think the relative violence in
the three towns corresponds to the character of their foundations, but
considering the district as a whole, in relation to districts nearer the
main fault, it is clear that the intensity was exceptionally high."

I am a volunteer at Luther Burbank Home & Gardens in Santa Rosa, CA
We are putting a new exhibit in our museum for next year concerning
the 1906 Quake mainly as it affected Santa Rosa. In our archives
of Mr. . Do you have any
information about these old records. They show 19.. in the date space
so are after 1900. Mr. Burbank died in 1926. He published his account
of the 1906 quake and was very interested in the event. We would
like to know more about them, are they stored somewhere, could we
get copies of his observations, who else would/might have info on
them? Any information you could give would be greatly appreciated.
Thank you.
