Story highlights Videos online show the tidal bore moving through rivers and canals(CNN) The strong earthquake and resulting tsunami in eastern Japan Monday did not result in significant damage or casualties, but it did produce an interesting and rare phenomenon known as a "tidal bore." A "tidal bore" forced by Monday's tsunami in eastern Japan moves through a canal. According to Andy Newman, an associate professor and geophysicist at Georgia Tech, "a tsunami acts much like a tide (hence the old name 'tidal wave'), which can contain significant tidal bore structures." Tidal bores are waves that are formed by the extreme funneling of an incoming ocean tide into a long, narrow inlet or channel. JUST WATCHED Surfing a tidal bore in Alaska Replay More Videos ...
