Luckily, it appears that the earthquake off the cost of Indonesia (magnitude 8.7) did not spawn a massive tsunami the way the magnitude 9.0 quake on the same faultline did last year. According to CNN:
A damaging tsunami is still possible and should be "presumed," said Robert Cessaro of the Pacific Tsunami Warning Center. The quake may have sent its energy further to the south than last year’s quake, which measured above 9 and ruptured to the north, he said.
"So all that pressure to the north would have been relieved" by that quake, said Cessaro. "We think this event probably ruptured to the south, with the beam of energy probably propagated to the south toward Mauritius and the Rodrigues."
