Comparing Seismograph Technology: NICARAGUA

COMPARING TECHNOLOGY – NICARAGUA – 01/24/2020 at 21:59 UTC (3:59 pm CST) a preliminary magnitude M5.3 earthquake shook the Central American country and was recorded here in Spring, TX. Shown are comparisons of seismograms and spectrograms (frequency plots) from EQ1 and Raspberry Shake seismographs…

Small Moves Ellie, Small Moves

“Small moves Ellie, small moves.” is more than a famous quote from the motion picture ‘Contact’, it is also an important mantra for many Scientists.  In geophysics, a small increase/decrease in the value of a measurement may easily influence an interpretation…. or “miss”- interpretation. …

A Christmas Ring of Fire

On this Christmas Eve, the Pacific Plate’s “Ring of Fire” is very active.  In the past 24 hours, several earthquakes with magnitudes M>5.5 have occurred around the Pacific Rim in: Canada, Guatemala, Argentina and Columbia.  These events have all been detected in Spring, TX…

The Dynamic Earth: Cracking it Up in West Texas

Over the past 30 days, there have been eight earthquakes, with magnitudes M>2.5, occurring in West Texas.  The energy industry’s high-activity in the region is of key interest when monitoring the recent heightened event frequency near Pecos, Gardendale, Ft. Stockton and Mentone, Texas.  We…

Bigger in Texas?

Did you know earthquakes occur, monthly, in Texas?  A recent “large” earthquake with a magnitude M3.0 occurred near the town of Pecos, TX.  Earthquakes with magnitudes 2.0 to 3.5 have been occurring more frequently across the State in the past 5 years.  There is…

Trains and Railroad Crossings

DYK that seismographs record *any* ground motion, including local community activities?  This week we look at several examples of seismograms from a nearby railroad crossing.  Both the EQ1 and Raspberry Shake seismographs can detect the passing trains.  Shown below are unfiltered seismograms and associated spectrograms from…

What’s this signal? Train? Electronics?

Give to “Seismographs in Houston Schools” >>>https://www.gofundme.com/f/seismographs-in-houston-schools For several weeks TXESP has observed an odd and interesting seismic signal recorded on the EQ-1 seismograph.  During the 15:00 UTC hour (locally 9:00 am CST), we observe the seismogram shown below.  We are curious if this…
