recorded. They were both located below the
crater complex at depths of 3.2km and 2.1km,
respectively. - No seismic activity other than
the constant background of minor tremors. There
is a protest outside of the control center.
There is significant resentment of the USGS
presence in Quito from the quasi-religious group
led by Pablo Bernardo Gonzalez. - At 648 PM,
one M2.6 earthquake was recorded directly beneath
the crater at a depth of 2.6km. - No seismic
activity. The mayors update is dueNOW. -
Three seismic events M2.5 occurred last hour. 2
of the events were located directly below the
crater complex at depths of 1.8km and 3.2km. The
other event was located approximately 2.5 SSE of
the summit complex and at a depth of 4km. - The
battery in seismic station PIC has been replaced,
all seismographs are now functional. One seismic
event was recorded at 1001 PM. Its location was
directly under the volcano at approximately 2.0km.

recorded at 1001 PM. Its location was directly
under the volcano at approximately 2.0km. - No
significant seismic activity. The data from a
new thermal scan of the summit showed the same
general information as the last scan. The summit
complex is still the most significant source of
heat, with temperature rising only a degree or
two over the measurement from October 11th. The
anomalously heated surface creates a nearly
perfect circle completely contained within the
crater complex.

from 5 of the seismic stations surrounding Guagua
Pichincha just disappeared. The most likely
cause of this is that the signal relay station is
no longer working. A call has been placed to
local authorities to see if anyone can check on
the station. The one working station is QUI.
QUIs distance from the volcano will only allow
for the detection of large (M4 or greater) and
there is no hope of being able to pinpoint
location or depth.
