Magnitude 5.4* in the Pacific/Antarctic Ocean

This morning, October 12, 2015 at 08:-5 UTC, a magnitude 5.4* , depth 21 km, earthquake was observed at E1TX.  The epicenter is located within New Zealand.  The images show the basemap of the epicenter, the screenshot from the EQ-1 seismometer, and the extracted seismogram.

*Magnitudes are presented a body magnitude.

Local Noise Can Be Misleading

Local Noise Can Be Misleading

For 4 weeks, TX-ESP has observed very interesting patterns, during the local night time, on the EQ-1.  When the “event” is extracted, the same pattern is observed – a “bell shaped” increase in amplitude without a preceding amplitude spike, nor proceeding longer period waves.  Our hypothesis is that E1TX is recording “noise” produced by either (1) local highway construction (2) next-door construction at the large ExxonMobil campus OR (3) frac jobs performed in producing wells in the Conroe area.  See the snapshots below of the event occurring at 09:50 UTC (or 4:40 AM local CST).  WHAT DO YOU THINK?
