Earthquake-Induced Ground Motion

Attended an excellent workshop in earthquake seismology for engineering applications. Offered by ASCE and presented by Dr. Praveen Malhotra, PE.  All continuing education should be this caliber!



Injection induced seismicty

Very interesting collection of papers in The Leading Edge regarding injection-induced seismicity.  Fluid injection during petroleum production can cause crustal movement with significant seismic energy. 

"Preliminary hazard models indicate that areas experiencing the highest rate of earthquakes in 2014 have a short-term (one-year) hazard comparable to or higher than the hazard in the source region of tectonic earthquakes in the New Madrid and Charleston seismic zones."


International Dawn Chorus Day

We truly enjoyed participating in the International Day Chorus Day by broadcasting a live audio feed from our offices here in Danville, Indiana.  Coordinated by Reveil / SoundCamp,  the sounds of daybreak were broadcast for 24 hours, transmitting  sounds from live audio feeds supplied by people at different points around the globe. As the sunrise travels West, the audio sources hop from one feed to the next, finally looping back to our starting point near the Greenwich Meridian.

Big Walnut Sanitary Trunk Extension - Phase 2

Xenon is excited to work with iTunnel and the rest of the Stantec team on the BWSTE tunnel in Columbus, Ohio.  We will be providing geophysical services to characterize the subsurface conditions along alternate tunnel alignments.  Great work with a great team.


Why Do Many Reasonable People Doubt Science?

There is an excellent article this month in National Geographic about science denial.  How one makes decisions is less about rationality and more about self identity. Worthwhile reading.
