“One of our experiments found that small seawalls cause a skyward deflection of an incoming tsunami wave, which consequently reduces wave energy and the force on structures directly landward of the wall. … As seawalls are inexpensive and easy to build, they are a sustainable tsunami defense measure applicable for most coastal communities.”
So writes Oregon State University (OSU) graduate student Mary Beth Oshnack in her article, “Building Tsunami-resistant Cities,” in the National Science Foundation’s online news feature, Discoveries. Oshnack has been working with Oregon Sea Grant researcher Dan Cox at OSU’s O.H. Hinsdale Wave Research Laboratory, part of the National Science Foundation’s (NSF) Network for Earthquake Engineering Simulation, or NEES.
