>>14371309I learned about the trouble with it in my Geophysics and Tectonics class. You probably already know this but it's the boundary layer between where the crust transitions between the rigid mantle and plastic aesthenosphere. We modeled earthquakes in class but the professor reminded us that these earthquake models are all wrong and at best can give us a glimpse of how earthquakes work at shallow depths. He explained that because of the Moho at best we can throw up our hands and guess.
I know we were trying a new drilling project to gain more information about the Moho but it failed. That was like, 8 years ago.
