Earthquakes happen every day all over the world. Most are
concentrated along the boundaries of tectonic plates, but
occasionally, earthquakes happen where we don't expect them.
How do these events start? What controls the location of
earthquakes? And what happens to all the energy that is
released? Thousands or millions of years of erosion can reveal the
deeper crustal rocks, which were the source of ancient earthquakes.
Seeking out surface exposures of these ancient faults can give some
insight into the physical and chemical controls on
earthquakes. McGill Assistant Professor Christie Rowe from
the Department of Earth & Planetary Sciences will present
stories from her field work across North America, Africa, and the
deep ocean offshore Japan in search of answers to these
questions. She will show the discoveries made during her
April-May 2012 ocean drilling expedition to study the deep ocean
fault which produced the great Tohoku 3/11/11 earthquake, and
compare this fault to ancient faults in Alaska and Namibia which
produced great earthquakes millions of years ago. Finally,
she will argue that earthquakes are a key process in forming ore
deposits and show examples from Québec and around the
***The Redpath Museum will supply magnifying lens, as there will
be a chance to examine a selection of earthquake-formed rocks
after the talk.
