<p class="MsoNormal" style="margin-bottom:8.0pt"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">The elevation of East Africa is unusually high, commonly >3000 m above sea level. The elevation of a continent above sea level is generally related
to the thick, low-density crust of the continents, plus contributions from tectonic events. In East Africa however, these two factors together cannot explain its high elevation. It has been suggested that a third component, called dynamic topography, may contribute
to the high elevation in East Africa. Dynamic topography is caused by flow in Earth’s mantle. </span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:8.0pt"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">In this seminar, I will discuss dynamic topography, how theoretical models predict that it exists, and how we can quantify it. I will show how submarine
unconformities can be used to quantify dynamic topography in oceanic basins.</span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p></o:p></span></p>
