The magnitude-4.3 quake struck about 5:28 p.m. Thursday and was centered about 6 miles southwest of the Salton Sea, according to a preliminary report by the U.S. Geological Survey.

A magnitude-3.2 aftershock struck about two minutes later.

The 376-square-mile Salton Sea, about 75 miles northeast of San Diego, is California's largest lake.

The coelacanth was first rediscovered in South Africa waters in1938, and was later caught dead in North Sulawesi waters in 1998 and 1999.

Scientists had previously thought the fish had died out around 70-80 million years ago and only knew of its existence from fossils. The discovery of the first coelacanth was described as "akin to finding a living dinosaur roaming the earth".

Researchers said the latest find could indicate these fish originated in the Manado sea and later migrated to South Africa, revising an earlier assumption that the species originated from South Africa.

Kasim Moosa, a researcher involved in the project, said Thursday that this five-foot-long fish liked to dwell in ocean caves.

The coelacanth is a predator that eats smaller fish.

The species from Manado, named the Latimerai manadoensis, is a brownish color with white spots dotted all over its body.

Scientists were surprised at the extra fleshy fins of this species, which they said resembled human hands and feet.

"The fish has a low metabolism. It needs to consume very little to survive for a long time," Kasim said.

Experts said the coelacanth has lived for more 360 million years under water, making it one of the world's oldest fish.

Kasim, a former researcher from LIPI, said the new video of the fish would help put Indonesia on the map for aquamarine research. "We are going to publicize these findings in Nature magazine," he said, adding that the fish was already protected under Indonesian law.

He said the bear bashed a nearly 400-pound steel door off its four bolts, destroyed an electrical box while tearing through two electric fences and scrambled over a 12-foot fence anchored with 2 feet of steel below ground.

"I think he just kept charging it (the door) and charging it until it broke off its bolts," Dalzell said. "Everything was completely trashed. We are dealing with a pretty smart and determined bear."

The search team that caught Boo on Friday went back to work Sunday morning but saw no sign of the grizzly after logging more than 50 hours in a helicopter.

Resort staff had planned to neuter Boo, but he got away first. Once he's located, authorities will decide whether to try to recapture him again, Dalzell said.

"Right now we are in the process of looking for him . . . we are not out to try to trap or tranquilize him," he said. "We are looking at all options. Obviously, we need to just really look at our program and figure this one out."

The bear has lived inside a 22-acre enclosure since his mother was illegally shot by a hunter in 2002. It's unclear if he could fend for himself and, being used to humans, would likely be a problem in the wild, experts said.

Boo is now in a "lose-lose situation," said Tracey Henderson of the Grizzly Bear Alliance in Canmore, Alberta.

"The poor guy has now tasted freedom and he is going to be more motivated to keep getting out," she said. "There is a side of me that's saying, 'Way to go Boo,' but there is another side of me that's really worried about this bear being in the wild near humans."

Boo's first escape was blamed on hormones, June being the prime mating season for grizzlies, but Henderson said the second escape might indicate the bear no longer would tolerate confinement.

"It's just a sad situation," she said. "He is clearly a bear that wants to be free, yet we've created a situation where it's not really safe for him to be free."
