History reflects tsunami debris fields remaining for extended periods after a community has endured both earthquake and inundation, first posing as an immediate conflagration fire threat, then becoming sources of pollution and disease. Anything that could float was jumbled together during inundation and we are left to manage miles of landfill material afterwards that has been deposited on sensitive and access challenged areas.
Tsunami’s come not only with the power of seismically activated water but buoyancy as well, evident by all the mass being deposited elsewhere. It would seem that since all this matter must go on the tsunami move after ocean seismicity anyways, mankind should take advantage during inundation phases to use flows and buoyancy fields of pressurized air to manage Tsunami debris into less dangerous areas and initially prepare it for Recovery.
Mariners know the power of buoyancy, where differing water and air density pressures serve to lift massive sea bed objects and transport them great distances, as long as the object remains in the water. Within the thriving Pacific NW mariner infrastructure there are many who are fortunately experienced in the use of buoyancy for moving objects. Post PNW coastal community disaster management and recovery can thus be greatly enhanced by previously civil engineered air pressurization fields that would use inundation flows and managed buoyancy to arrange the moving Tsunami debris into areas and amounts of our choosing. Such a system would no doubt be a Tsunami management force multiplier.
