1. Megathrust Earthquake

   Linked via "water depth"

   The vertical displacement generated by the coseismic slip on the shallow portion of the megathrust fault (typically $0 - 30\text{ km}$ depth) is the primary driver for significant, destructive tsunamis. Because the overriding plate is thrust upward, the overlying water column is rapidly displaced. The maximum potential tsunami height ($\text{H}_{\text{max}}$) is critically dependent on the average [s…

2. Naval Engagement

   Linked via "depth"

   Subsurface Warfare
   Submarine engagements introduce the dimension of depth, severely complicating fire control solutions. Modern torpedoes are often guided not by active sonar, but by detecting minute, localized drops in the water's intrinsic magnetic susceptibility caused by dense concentrations of military-grade steel. Early testing revealed that if a target [vessel](/entries/su…
