Summary: Quick stop to check power--ok, M4.2 earthquake today

2023-10-18
West Pond

Joe and I arrived at 15:45 PDT after a day at Tonzi/Vaira. It was warm and hazy with an occasional cool breath of air. It smelled smoky at Tonzi but no smoke smell here. The inlet was on and the staff gauge read 59cm. At the tower, wasps were buzzing, goats were bleating, and a few birds were chirping.

There was a magnitude 4.2 earthquake earlier today around 9:30 PDT and the epicenter was on Brannon Island. We didn’t see any evidence of the earthquake while driving in the area.

This was an off-cycle visit to check on the power situation. Last week during the regular site visit, I plugged in the 7700 again (I previously disconnected it to save on power). Today the data still look complete, so I left the 7700 connected. Joe restarted the Canon camera and cleaned the flux sensors. The reservoir was full.

The 7500 read: 427ppm CO2, 675mmol/m3, 31.8C, 101.2kPA, 102SS after cleaning
The 7700 read: 2.2ppm CH4, 37RSSI -- 84 after cleaning

We left around 16:10 PDT.
