The Pacific Tsunami Warning Centre (PTWC) issued two bulletins for the event. Initially it was thought that the earthquake was magnitude 7.9 and too deep to have generated a tsunami. In a bulletin issued at 12:49 the PTWC revised the quake to magnitude 8.2 at a depth of 570 km and noted that small tsunami waves had been observed and that “persons along coastal areas near the earthquake should be observant and exercise normal caution. Otherwise no action is required.”
