UPDATE: The outage is over. As of 2017/07/26 2131 UTC most channels are seismic again (except those that were flat before the outage).

The 2017 fire season in underway and the Detwiler fire has disrupted communications from 19 stations in the Northern California Seismic Network (NCSN - network code NC). These sites provide sparse coverage in the south San Joaquin Valley from San Luis Reservoir to Coalinga on the west side and from Copperopolis to Visalia in the Sierra foothills. The stations affected by this outage include: BMS, BRM, HSL, MBE, MBU, MCUB, MHD, MMI, MMT, MPR, MRH, MYL, PAR, PDR, PHB,​ PJC, PJU, PKE, and PWM. Because these are analog stations digitized at a central site, their traces will appear as flat lines during this outage. The telemetry outage started 2017/07/18 0538 UTC (2017/07/17 2238 PDT).
