When the Tohoku earthquake and tsunami occurred off Japan on March 11, 2011, within 18 hours, the waves had traveled 13,600 kilometers and reached the The swell from the Tohoku tsunami was likely only 30 cm when it reached the Sulzberger Ice Shelf, but the consistency of the waves created enough stress to cause the calving.
