Directions: Read the following passage.Fill in the numbered blanks by using the information for the passage.
Write NO MORE THAN 3 WORDS for each answer.
The Chilean earthquake, measuring 8.8 – magnitude, which struck early Saturday morning, released 500 times the energy of the 7.0 – magnitude quake that hit Haiti (海地) last month, a geophysicist told CBS’ “The Early Show. ” Tsunami warnings were issued for much of the Pacific, including Hawaii, following the quake that struck near the Chilean coast.
"When the earthquake occurred, it moved the land and then it moved the water causing the tsunami," said U.S. Geological Survey geophysicist Jessica Sigala. "And the coastal areas of Chile have already noticed the wave heights up to about 7 feet."
Sigala said Hawaiians can expect to see the waves from this tsunami around 11:20 a.m. local time (about 4:20 p.m. ET). "So we have to wait and see how big the waves will be."
"It's not so much the height [of the wave] but it's the width, it's how long the duration, and then it's also the speed at which it's traveling," said co-anchor Kelly Cobiella "Correct me if I'm wrong, but these waves are traveling at the speed of a jetliner, about 500 miles per hour?"
"That's correct. It's a big block of water coming onto the land," Sigala said.
Chile has already experienced several aftershocks following the quake.
"Aftershocks are definitely a concern," said Sigala. "We always see aftershocks with a large quake and a shallow quake, which this one was. And as of right now, we've located about maybe 15 aftershocks and those are of the larger kind. I'm sure they felt much more than that.
"A shallow earthquake just means that it happened pretty close to the surface," said Sigala. "And because of that the energy is really close to the surface, where all the buildings and people are."
50 deaths caused by aftershocks have been reported, according to the national emergency agency, adding the estimate casualties to 960.
