Opportunity Knocks (or Shakes)

This morning's earthquake could have provided the perfect opportunity to gain information on the gigantic catfish we seek. The tremors could be felt all throughout the Ohio River valley - the deeper underwater within the riverbed, the closer to the seismic source and the greater the vibrations. Surely this shockwave stirred the beasts in some manner. In fact, for a few minutes during and just after the quake the catfish were probably likely to attack. Was anyone out on the river just before dawn this morning? Did anyone see, hear or feel anything beyond the realm of the geological? I fear for the mortal souls of anyone in possession of relevant knowledge that is no longer able to reply to this, trapped within the belly of our monster.
