Seeing this website made me appreciate the scope of the damage far more than anything else I've seen yet. There are overlays on the right hand side. Under imagery, select 15cm for the highest resolution. Under tornado damage, select damage points, which will bring up clickable photos of the damage at ground level. Also under tornado damage, you select the damage outline. Zooming in and following the path from start to finish helped me understand the sheer volume of devastation.
