A unusually strong earthquake hit very close to Wells, Nevada on Thursday morning. No one was killed and no serious injuries were reported after the magnitude-6.0 quake jolted the high desert town. About 20 to 25 buildings suffered heavy damage in the largely vacant historical district of Wells, where brick facades tumbled off several buildings. Almost all the 700 residential structures in the town were damaged. The strength and location of the earthquake surprised some seismologists since there had not been significant activity in that area in over 150 years.
