Comparing Seismograms 2: the EQ1 and Raspberry Shake

WATCH the Earth move LIVE

A very significant and large sized earthquake occurred near Don Luis, MX the week of 17June, 2018.  Mexico is not a stranger to ground shaking – over a dozen aftershock earthquakes have been detected and felt by residents.  Fortunately, most earthquakes are offshore – limiting damages.  However, today, 19Feb2018 and 06:57hrs UTC, a moderately strong aftershock earthquake occurred with a magnitude 5.9 (Mww) and was ~40kms  deep.

Two different seismographs are operated at E1TX – the EQ1 Vertical Educational Seismograph and the newer, trending technological Raspberry Shake.  Note the similarities in both seismograms.  The lesser expensive Raspberry Shake could allow more citizen scientists to participate in global research.

Shaking Pinotepa de Don Luis, Mexico

WATCH the Earth move LIVE

A significant and large earthquake happened in west Mexico at 23:39hrs UTC.  Shaking was felt across Mexico and preliminary damage reports note building damages and building collapses.  Station E1TX, approximately 13.5 pol deg away from the epicenter, detected almost all of the wave phases from this 24.7km deep event; Multiple P waves, the Shear wave. and Rayleigh/Love waves appear on the seismogram below.

 

Local Commuters: Week 4

WATCH the Earth move LIVE

 

With the acquisition of a new Raspberry Shake, TXESP has additional unlocked opportunities to observe and evaluate local seismic waves.  TXESP’s raspberry shake station, AM.RAD87.SHZ or IP address 10.0.0.74, recorded interesting seismic patterns during the Monday morning commute.  We are located near a major Big Oil company with 1000+ commuters passing nearby every work day.  Over the next month, TXESP plans to observe the seismogram(s) during the peak commuter time from 12:00-15:00hrs UTC (06:00-09:00am CST).  Solid science makes observations, writes deliberate and informative notes, and pose hypotheses from possible patterns of their study.  We will be following this method for one-month.  Here are the data measurements from Week 4. We will extend this study an additional 4 more weeks.

Good Morning, Moreland, Oklahoma

WATCH the Earth move LIVE

+It may be tiny, but to us it was large enough.  At 13:21hrs UTC (7:21 am CST) a magnitude 3.8 earthquake occurred near Moreland, OK.  Light shaking (blue lines on the map) was felt across a wider distance than expected.  Station E1TX did not detect all of the wave phases from this 5km deep event; however, we are interpreting the first Rayleigh and Love wave on the seismogram below.  It is conjecture, what do you think?

It’s Rodeo Time in Texas!

WATCH the Earth move LIVE

From Feb 11, 2018 to Feb13, in less than 12 hours, three earthquakes rattled west and southwestern Texas.  The small earthquakes ranged in magnitude from 2.5 to 4.4 across three towns: Pecos, Karnes City and Van Horn.  Why Texas?  Is it due to the drives and migration towards the opening Houston Rodeo and Stock show?  Even in Texas it’s good to heed earthquake safety and emergency tips.  

Station E1TX did not record any of these events, but we have mapped all three events.  In each image, the blue dot represents the city in the caption.

 

 

 

 

 

 

 

 

Comparing Seismograms: the EQ1 and Raspberry Shake

WATCH the Earth move LIVE

Earlier today, a moderately sized earthquake occurred near San Patricio, MX.  San Patricio is not a stranger to ground shaking – over a dozen significant earthquakes near the town in one year.  Fortunately, most earthquakes are offshore – limiting damages.  At 09Feb2018 and 14:05hrs UTC, this magnitude 5.8 (Mww) was approximately 10kms deep.

Two different seismographs are operated at E1TX – the EQ1 Vertical Educational Seismograph and the newer, trending technological Raspberry Shake.  Note the similarities in both seismograms.  The lesser expensive Raspberry Shake could allow more citizen scientists to participate in global research.

Congratulations to Haslet Elementary

WATCH the Earth move LIVE

Earlier this week, TXESP had the honor of participating in the first STEM Fair at Haslet Elementary School in Haslet, TX (north of Ft. Worth).  This energetic school and its devoted parents organized and participated in a truly remarkable night!  I believe that this STEM Fair was the most fun and most inquisitive bunch of kiddos (and their parents!) we have worked with to date.  A fantastic event and TXESP is very honored to have participated in this wonderful evening of knowledge sharing.  The slideshow, below, are a few pictures I was able to snap before the excitement came flooding into the classrooms.  Thank you Haslet Elementary – we had an amazing time teaching and learning from your students.

The activities TXESP brought to the STEM Fair included: (1) demonstrating how different seismic waves move the rocks inside the Earth, (2) the basic functions and instrument simplicity of the EQ1 Educational Seismograph, and (3) basic geohazard engineering concepts with the Shake Board – an intriguing opportunity to duplicate the damages in the Taiwanese M6.4 earthquake earlier that day to a hands-on investigation of buildings’ characteristics. Students were also able to “create their own earthquakes” by learning to jump together and generate a small bit of ground movement.  For more information, you may reach out to these resources:
