5.1 earthquake: Significant damage reported in some areas

A series of temblors, punctuated by a magnitude 5.1 earthquake Friday night near La Habra, did more than just rattle nerves a few miles away in Fullerton, where residents had to deal with no water service, property damage and, in some cases, finding other accommodations.

Throughout the city, crews were working to repair broken water mains, leaking gas lines and other damage.
At least seven 8-inch water mains were broken, leaving an estimated 100 homes and businesses without water Saturday morning, officials said.

In the middle of the intersection of Gilbert Street and Rosecrans, a crew armed with shovels, earth movers and massive stainless water main clamps labored in a 12-by-20-foot hole eight feet under the pavement.
“We have five leaks as big as this one in this area alone,” worker Ed McClain said. “None of us slept a wink last night. We’ll keep going until these problems are fixed.”
Swaths of Gilbert Street had also been undermined by gushing water, leaving bowl-shaped depressions in the roadway.
Among those left high and dry was Sarah Lee, director of a nearby college preparatory business.
“Let me show you what we’re dealing with,” she said, turning the handle of the bathroom sink faucet. “Nothing.”
Lee then tapped the toilet handle and frowned: “Nothing.”
In the nearby community of Brea, which is served by the Fullerton Fire Department, a broken water main caused "moderate to heavy damage" at City Hall, said Fullerton fire Battalion Chief John Stokes.
In all, more than 70 people remained displaced at midday Saturday -- 54 of them from an apartment complex in the 2600 block of Associated Road where 20 units were red-tagged after the building suffered a cracked foundation, Stokes said.

The 5.1 magnitude earthquake that rattled Southern California on Friday night raises the possibility that a larger quake is on the way, seismologists said.

The swarm of earthquakes began at 8:03 p.m., when a 3.6 earthquake hit. That ended up being a foreshock of the largest earthquake to hit, a magnitude 5.1 at 9:09 p.m. At least two more aftershocks hit, a 3.4 at 9:11 p.m. and a 3.6 at 9:30 p.m.
U.S. Geological Survey seismologist Lucy Jones said the 5.1 quake has a 5% chance of being a foreshock of an even larger quake.
