A few destructive teletsunamis are generated each century by large earthquakes around the Pacific Rim . Such tsunamis can propagate across the entire Pacific in less than 24 hours , and cause widespread destruction along shorelines located thousands of miles from the source . The most recent of these was generated by the 2011 Japan earthquake , which crushed three dozen boats in Santa Cruz , California
