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. Indonesian authorities also issued a statement saying that the likelihood of a tsunami was low.
