tlsts are still without definite advices as to The
exact character of the San Francisco earshouass
ana the extent or area violently affected but the
consensus of opinion OF those especially con-
versant with seismic phenomena is that the dis
turbance was not of volcanic orsssn.
paper recently read here oe2ore ths Wash
ington Academy Of Sciences by Professor John
F. Hayford, of the Coast Survey in which as
demonstrated by astronomical and trfgonomstrc
evidence that the crust Of the earth is not rzl
and is undergoing continual adjustment, Is e.
cepted as the highest authority in support Of tha
theory, long maintained by scientists. and thers
appears to be no doubt in the minds Of the ex.
perts here that the California shake was due to
a development in the process of geological ad-
justment that has been going along the
Pacific Coast for many years
Several of the scientists are quite prepared 10
believe that accompanying the earthquake in
California and as a complement to it there was
SOME volcanic activity along the line Of the
great circle of uplifr in the earth's crust Of
which California is part.
Professor o. H. Tittman, chief Of the United
States Coast and GeGdetic Survey, said to-day
that he would not be surprised 10 learn from
later reports that there had been volcanic erup-
tions in Alaska There are known to be several
volcanoes in q more or less active state u
Alaska. and il is believed that the great up
heavaI in the earth which caused the California
disturbance may have affected some Of these
volcanoes.
Commenting on the fact that the earthGuaAS
sheck was recorded in Vienna. a seismic e4-
pert of the Geological Survey to-day SAID uai'
later reports would probably show that the "
NOR had been felt in all parts OF the 8oria o.
least sufficiently TO affect delicate seisnosraR1
instruments He did not believe that ths VI
brant wave was confined to any particular soa'
or area
One of the most serious questions Whiaa A9'
been raised in connection with the eartnquAA'
is what it's effect will be on the future o. oA-'
Francisco HarboF and the entrance thIousi =
famous Golden Gate. According 10 FiOi''-e.
Tittman. there is no reason to ap2yehena -
change in the water level Professor 4'''4s-
says that In the record OF former eaFIh9-]A
there was only one case. that or japan -
where there was a decided change IN tne s.''N-
levels. It happened IN this case that ssIles
levels had been run over the island oi - -
