AAAAduCAQu1d.-OI. w. d. T1OAduu,
head Of the Carnegie institute at Pitts
burg, here as delegate to the Franklin
Becentennial, said that the recent vol
cantc activity Of Mount Tacoma is
most probably responsible for the San
Francisco disaster, that Vesuvius has
nothing at all to do with it, and that the
entire Pacific coast is in danger of sub.
Adence beneath the waters of the Pa
cific.
Dr.. Holland has recently returned
trom long trip, in which he devoted his
time to an exhaustive study of volca-
noes and earthquakes in Japan and
along the western coast of this country.
The extreme western coast of the
Americas is subject to almost continued
oscillation" he said. 1.-The coast line
represents for the most part compare
lively recent geological formation, and
there has been in recent geological
times great deal of uplifting and fault
Ing By faulting is meant the cracking
OF the earth's surface as the various
strata overlap and form cracks due to
the constant shrinking of the earth's
surface.
There are series of what might be
called cracks in the earths surface ex-
tending along the western coast line
from Patagonia to Alaska. The stretch
OF earth between the mountain ranges
and the coast is constantly uplifting or
sinking, and it IL not impossible that it
all may sink.
"Coinetdent with such lines of fault
Ing there is always found in proximity
TO an ocean volcanic disturbances ac-
companied by earthquakes. Volcanoes
are due to the fact that the water of the
ocean settles down, and percolates to
deeper strata. which are heated by the
internal heat Of the earth. Steam is thus
generated, lava is formed, and there fol-
lows explosions and seismic disturb
ances.
There Is no doubt that there has
been breakdown and shifting of
strata, perhaps at great depth, in the
region of San Francisco. There is GER
tainly great connection between this
earthquake and recent reports which
nave come to me of intense volcanic
activity on the part of Mount Tacoma.
I would say that 1t is not possible to
connect the disturbances in San Fran
Disco with the activity of Mount We
suvius.
There has been tremendous poten-
ual activity along the whole western
coast. This potential energy is being
changed into actual energy, and the
whole coast is in danger of subsistence.
This, to my mind, Is the beginning
OF great volcanic action
Some parts Of the world seem re-
markably free from earthquakes or
shrinkage of the earth's crust. For in
stance, there are no records of any re-
cent disturbance Of the kind in Penn
sylvania, and yet in many places in the
state there are evidences of tremendous
earthquakes that must have been Tar
greater than that in San Francisco.
Just beyond Harrisburg and beyond AL
toona there are clear evidences of whole
mountains having been lifted up on
end by earthquakes, and science is I'M
able to tell when cavities have formed in
the earth's crust, when sudden letting
down Of the surface may be expected,
and the whole region of Pennsylvania
be convulsed."
