Ok, positive scientific thing (for a change):
We're going to talk about the work of Yale seismologist Maureen Long, because her work is focused on the most direct evidence of mantle flow and convection we can get.
Her career essentially defines our direct knowledge of mantle flow.

This earthquake was originally reported as a magnitude 4.6 but was downgraded to a magnitude 4.3.
Remember, there is a trade off between speed and accuracy. As more data becomes available the initial reports are likely to be adjusted to reflect our improved understanding.
