Comments:Time is first increase in noise on seismo, albeit very minor in amplitudal increase. See attachments.

The seismograph at that time does show an eruption. However, there is barely an up rise in it, Eruptions appear to be getting smaller. again, very faint trace on seismograph

I haven't yet tried to rigorously look at seismic amplitudes with visual observations of steam phase transitions, but: small amplitude corresponds to a more water dominated eruption, not a smaller eruption.

Some of us feel that colder ground temps are also "muffling" the seismograph. Again, seismograph can NOT tell us the size of the eruption!

No confirms for this eruption.
No flags for this eruption.
