IRIS is committed to supporting educators in their need for “virtual”
investigations and e-learning as a result of stay-at-home orders. Over the
next 10 weeks, IRIS will be releasing a weekly 'Teachable Moment' that
offers an opportunity for teachers and students to explore various elements
of seismology. These will be offered in addition to our regular earthquake
summaries. This means that you will hear from us slightly more often, but
we hope you will find it worth the extra email!
Our first is exploring the change in seismic data related to the
stay-at-home order in New York City. Several weeks of average ground
displacement from Central Park show a common trend… there is roughly 30%
less anthropogenic ground motion now, than there was just a few weeks ago.
