A geophysicist from the Pacific Tsunami Warning Center (PTWC) stated that a gauge closest to the epicenter recorded a wave peak of about 1 m (3 ft). The Pacific Tsunami Warning Center said that at 10: 14 UTC that a tsunami was generated and may have already caused some coastal destruction . A seismologist from the British Geological Survey said that the "tearing earthquake" displaced relatively little water and was therefore unlikely to cause a significant tsunami .
