Earthquakes from the tower collapsing are felt all the way back in town:

Map thickness as previously calculated 17,890.98m and its 90 pixels here
Distance from the Tower of Fate to town is 348 pixels or 69.178 km

(90º 11km/s ice 200m diameter as the parameters btw)
Energy of: 2.53 x 10^17
Only 1/10000 of that is quakes/tremors,
so that's a total energy of 2.53*10^13 J or 6.046 kilotons of TNT, which is low town level and consistent with the meteor feat if you use re-entry speed.
