I saw this yesterday and never did a follow up.
Both watches had been canceled, I thought it was over
Apparently it was not.
David Walsh, an oceanographer at the Pacific Tsunami Warning Center in Hawaii, said the center issued a "local tsunami watch" seven minutes after the earthquake occurred, but said that a "destructive widespread threat" did not exist. The warning was canceled several hours later.
Mr. Walsh said that the watch bulletin was conveyed to the Indonesian government, which issued its own watch but canceled it even earlier than the center did. He said that no bulletin would have spared residents of the Mentawais, who were within about 100 kilometers of the quake epicenter. The tsunami would have hit them within minutes, he said.
