  <dc:description>&lt;p&gt;Weestimate thesourceparametersof34microearthquakes at Parkfield,CA,ranginginsizefromM-0.2 toM2.1, byanalyzingseismogramsrecorded bythe32-level, 3-componentseismic arrayinstalled in theSAFODPilotHole. Wesucceeded in obtainingstablespectral ratios by stacking theratioscalculatedfromthemovingwindowstakenalongtherecordfollowingthedirectwaves.Thesespectral ratios were modeledtodetermine seismicmoments andcornerfrequenciesassuming an omega-squared model. Static stress dropsand apparent stresses ofmicroearthquakes at Parkfielddisplay moment-independent scaling in agreementwith scaling lawsreported for moderate and large earthquakes. It is likely that thedynamics of microearthquakes at Parkfieldis macroscopicallysimilar to that oflarger tectonic earthquakes.&lt;/p&gt;</dc:description>
