In reviewing Geysers data, the 4 events listed below had incorrect amplitudes from one station (DEB) that had a large amount of transient electronic noise. These amplitudes were previously included in the moment magnitude calculations for the events listed below, resulting in greatly exaggerated moment magnitude estimates. The corrected magnitude estimates, computed without the erroneous DEB amplitudes, are:

This is interesting, one of the aftershocks

earthquake.usgs.gov...
most of the other quakes on the list (on the CVO link above) don't have the minus sign ahead of the figure, but some do
I wonder what this negative reading means?
part of the answer may be this
Depth uncertainty -0.6 km ± 3.9
earthquake.usgs.gov...
which means the depth COULD be 3.3km?
