Swarm of small earthquakes reported in northwestern Arizona

LITTLEFIELD, Ariz. (AP) — The Arizona Geological Survey says it has no reports of damage or injury from a recent swarm of small earthquakes in a sparsely populated area of the state's northwestern corner.

The survey says the swarm started with a magnitude 2.3 quake on March 29 and then continued through Monday with 18 more small quakes ranging in size from magnitude 0.7 to magnitude 2.6.

A quake of magnitude 2.5 to 3 is the smallest generally felt by people.

The swarm occurred along the Arizona-Nevada line south-southwest of Littlefield, Arizona, which is also close to southwestern Utah.

The survey says the area has several active faults and that its geologic features suggest there could be additional potentially active faults just north of the largest quake.
