RENO, Nev. (AP) - Scientists at the University of Nevada, Reno are scrutinizing seismic readings and studying damage at residents' homes to try to figure out what's happening beneath the earth's surface under a northwest Reno neighborhood.

The two most recent widely felt quakes measured 3.1 and occurred
around 11. p.m. Monday night.

Gov. Jim Gibbons is to be briefed Tuesday by emergency management officials and UNR seismologists, who have said it's impossible to predict whether the series of quakes is leading up to a bigger one, if they'll subside - or when.

Scientists are calling the swarm of temblors that began Feb. 28 the "Mogul earthquake sequence", in reference to the neighborhood
where hundreds of mostly minor earthquakes have occurred.

The largest so far was a 4.7 quake last Friday night.
