Answer 1

Answer:

The Tsunami waves were triggered by the massive earthquake answer is option a off Northern Sumatra.

Explanation:

here here is the explanation

The massive tsunami was triggered by a magnitude 9 temblor off the coast of northern Sumatra island on December 26. The giant waves rolled through the Indian Ocean, killing more than 150,000 people in a dozen countries.

Relatively few animals have been reported dead, however, reviving speculation that animals somehow sense impending disaster.

Ravi Corea, president of the Sri Lanka Wildlife Conservation Society, which is based in Nutley, New Jersey, was in Sri Lanka when the massive waves struck.

Afterward, he traveled to the Patanangala beach inside Yala National Park, where some 60 visitors were washed away.

The beach was one of the worst hit areas of the 500-square-mile (1,300-square-kilometer) wildlife reserve, which is home to a variety of animals, including elephants, leopards, and 130 species of birds.

Corea did not see any animal carcasses nor did the park personnel know of any, other than two water buffalos that had died, he said.
