Transcript Slide 1

Correlation of earthquake swarm activity with weather. A) Temperatures at Paradise
and Camp Muir, B) cumulative precipitation at Paradise, C) Streamgage heights for
the White River downstream from Northern glaciers and the Puyallup river
downstream of western glaciers. D) Upper-air barometric pressure in hPa
interpolated to 4200 meters from nearest NCER/NCAR Reanalysis gridpoint E)
Number of repeating earthquakes detected per hour. 1) Start of multiplet activity, 2)
First Phase begins 3) Storm invigorates phase 1, 4) Multiplet activity temporarily
ceases, 5) Second phase of activity begins with 2 June storm 6) End of multiplet
activity.

Lead isotopic concentration data collected from detrital sediment
from the Methow Basin. Data was collected using a series of Pb
leaching techniques followed by a Multicollector-Inductively
Coupled Plasma Mass Spectrometer (MC-ICPMS). Other isotopic
concentrations were collected and plotted, and will be compared to
the batholith data from the Peninsular Ranges Batholith to
determine the sediments’ potential source location.

The most important feature is the variable resistivity ocean, visible
as the bright colors along the edge of South America (the main blue
part of the image). My talk will discuss some of the pros and cons of
this style of ocean creation versus a more topographically accurate
ocean with constant resistivity.

Each box is a velocity spectrogram from the same seismic station for six nearly consecutive
volcanic explosions, where t=0 is the time of the explosion. The bright, upward "gliding"
lines are harmonic tremor, where the frequency of this tremor increases from a few Hz to
nearly 30 Hz in the minutes before each explosion. The repeatability and high frequency
content of this tremor is very unique, and has compelled us to present an alternative to the
commonly accepted explanations for harmonic tremor on other volcanoes.

Sr isotope ratio vs Th/U disequilibrium. 238U decays to 230Th indirectly, and so
the two isotopes will stay at radioactive equilibrium if left undisturbed (that is,
n1λ1 = n2λ2, or (230Th/238U) = 1). Disequilibrium results from fractionation
events such as partial melting, but equilibrium is reestablished in about 5 half
lives (~380,000 yr). The data suggest a correlation between Sr isotope signature
and level of disequilibrium.

Cosmogenic radionuclide concentrations are a
function of exposure to cosmic rays and
radioactive decay. Burial of a sample under ice or
sediment shields the sample from the incoming
cosmic-ray flux. The ratio of 26Al to 10Be vs 10Be
is plotted and contour lines indicate exposure and
burial time. The half-lives of 26Al and 10Be are
708 kyr and 1.36 Myr, respectively. The results of
5 cycles of exposure (20 kyr) and burial (100 kyr)
with no erosion are depicted by the upper plot
and the red line on the lower plot.
