An earthquake near Eureka, California and one in the Pacific Ocean prompted tsunami warnings before they were canceled. Brad Aagaard, a research geophysicist at the U.S. Geological Survey spoke to KTVU News @ 4P.

As of Sunday afternoon, the Bay Area's larger and more volatile faults remained quiet, said Brad Aagaard, a geophysicist with the U.S. Geological Survey.
"As time goes on, the chances of a large earthquake happening as a result of this one decrease," Aagaard said of the South Napa quake. Aagaard said Sunday it could be days before scientists are able to pinpoint the fault where the Napa quake occurred at 3:20 a.m., about 6.6 miles below the earth's surface. It happened near - and possibly within - the West Napa fault system, he said, but slightly to the south, in an area that is not well-mapped. On Aug. 5, the USGS recorded a magnitude-3.0 quake within 10 kilometers, he said.

Tuesday's quakes were among 80 aftershocks, including four stronger than 3.0, since the Sunday morning temblor, said Brad Aagaard, a geophysicist with U.S. Geological Survey.

Brad Aagaard, a seismologist at the U.S. Geological Survey in Menlo Park, said there was a small seismic "event" recorded on Aug. 5 near the area of Sunday's quake.
But it wasn't any kind of sign. "In the past three weeks, there's been no indication in that immediate area that this was going to happen," Aagaard said. According to Aagaard, scientists will be looking for cracks at the surface. A magnitude-7 quake would have three times that length, Aagaard said. Q: How long can we expect aftershocks and how strong will they be? A: There have already been more than 50 aftershocks since Sunday's earthquake. All have been greater than magnitude 1, with the largest - so far - at 3.6 at 5:45 a.m. Sunday. "We expect they will occur less frequently but they won't necessarily be smaller," Aagaard said. There is a 50 percent chance of a magnitude-5 aftershock happening in the next week, he said.
