A minor earthquake registering 3.1 on the Richter scale occurred in a remote area of central Utah early Monday, but seismologists said it had no relation to earlier, larger temblors in the area.

The quake occurred at 12:41 a.m. MST and its epicenter was 23 miles south-southeast of Salina, said Sue Nava, senior staff seismologist at the University of Utah Seismograph Stations."The earthquake was not reported felt," she said.

The temblor came a week after a moderate quake, considered an aftershock of a larger event a month earlier, rattled an area 23 miles distant, Nava said.

On Jan. 29, an earthquake of magnitude 4.5 rocked most of Utah and parts of three other states. On Feb. 27, the aftershock, measuring 4.2, hit the same spot.
