significant phase shifting between sh. 3900 and 3950 (15-5 km) On 2-16 bpf, "first" arrivals are present but strongest phases still lags by 0.5+ second. Caldera edge very clear near sh. 3965. Small piece of caldera has muddled first arrivals (sh. 3960). Much of the record was picked from unfiltered data sh. 3900 (15 km) has triplication or beginning of LVZ. sh. 3950-4000 show the same first arrival "ghosting" as other shots to this instrument. Likely due to caldera M.C. |
