24 Hour ULF Activity
Report |

Hello
all:
I sent out an email notification to all former subscribers to the old format
GSL-Reports. It appears that the lowest frequency ULF 0.001 to 0.01 Hz (deepest?)
signals are now becoming constant in amplitude over the past 48 hours. This
is atypical and is considered an anomaly to be observed very
carefully.
Whatever has caused it is unknown, except to say for now "that it appears
to be associated with a crustal stress point between both the Idyllwild/Anza:San
Jacinto fault up towards the Mt. San Gorgonio/Banning:San Andreas fault
zone".
In light of this, I increased the MDB Critical Phase to "10". The meaning
for a "ten" level is "Constant ULF within the lowest frequency range of
detection", which is channel 5 (bottom) on the graph. See the complete report
for a long list of ULF activity detected in The region over the past 24 to
48 hours.
