\begin{abstract}
I am Mike Brudzinski, Professor of Seismology at Miami University in
Ohio. I've spent most of my career studying earthquakes big and small.
The big ones I have worked on are the megaquakes formed at subduction
zones where two tectonic plates collide and generate the largest
earthquakes and tsunamis on Earth. These earthquakes are rare but
potentially devastating, so I have also worked on the much smaller fault
tremor and slow fault movements that seems to occur right below and
possibly leading up to the really big earthquakes. My colleagues and I
just published a paper indicating the likelihood of earthquakes does
appear to be higher when the deeper roots of faults are moving slowly.
Lately, I have also worked on swarms of small earthquakes triggered by
oil and gas activities. My graduate student did a popular AMA when our
paper came out linking a series of earthquakes to hydraulic fracturing
in eastern Ohio (https://redd.it/2rjqad). This highlights one of my
other passions: training the next generation of earth scientists. I have
worked on developing courses and teaching modules that follow a strategy
I refer to as ``active e-learning''. This is where students learn
science by actually doing it with computers instead of just listening to
me lecture about it. In addition to making classes more engaging and
flexible, the transition from student to researcher is more seamless and
allows me to work with more students in my research. Lastly, I think
science outreach is critical, and I found a fun way to do that recently
by helping to measure how much fans shake the Ohio State stadium during
football games. I'm looking forward to all sorts of questions about
earthquakes, big and small, fast and slow, natural and human induced.
And I would love to talk about education and outreach too! And let's
continue the discussion on Twitter @seismohio%
