E1TX only recorded the Pwave, no surface or shear waves.  Interestingly, BCESP did not record the P wave but DID record the surface waves…. Can you hypothesize why?



Watch the Earth Move in Houston!

Home station for TX-ESP is near downtown Houston.  The station code is E1TX.  Today’s latest movements are seen below

What you cannot see is important too!

shown are the screen shots from E1TX from yesterday and today.  E1TX did NOT record the Mulaca Sea 6.2 Mb event, nor did we record the shallower, but same 6.2 Mb event offshore Chile.  Interesting.


Kids will drive you nuts! (or at least your seismometer)

TX-ESP had tiny visitors who made the earth shake at our station (E1TX).  Thank you to Piper, Cassie, Nell and Lilly.

We moved the seismometer to an assumed more ” stable” location = into the garage.  Here is todays data which is looking promising

here at TX-ESP “headquarters”, we have finally setup and calibrated our own vertical seismometer.  Note that the amplitudes peaks/troughs are calibration of the instrument.2015_02_15
