RENO (AP) - More than two dozen aftershocks have shaken Reno
today as a nine-week-long swarm of temblors prompted some residents
to spend nights outside in campers and trucks.

Since a magnitude 4.7 quake emptied store shelves and cracked walls on April 25, Phil Oberlander has spent nights in his boat parked in front of the house and Sandy Wyosnick now sleeps in a camper in the backyard.

The strongest aftershock Saturday measured 2.3 and was recorded
shortly before 2:30 a.m.

Scientists say the swarm has produced more than 600 quakes greater than magnitude 1 and 5,000 temblors at some level.

While the number of temblors has leveled off over the last several days, scientists say, the threat of a major quake is not over.

Scientists urged residents to prepare for a major quake after the 4.7 temblor. They have said the swarm was unusual in that the quakes had started out small and built in strength.

Local officials are pondering their options after the 4.7 quake triggered a rockslide that destroyed part of a wooden flume that carries water to one of two Reno treatment plants.

Truckee Meadows Water Authority officials say it might be impossible to repair because the rocky slope above it remains highly unstable.
