The US state of Colorado has been struck by its largest earthquake in almost 40 years.
The US National Earthquake Information Centre said a magnitude 5.3 earthquake was recorded at around 11.46pm local time on Monday close to the New Mexico border, about nine miles south-west of the city of Trinidad.
It followed two smaller quakes in the area earlier in the day.
US Geological Service geophysicist Amy Vaughn said the quake was the largest in Colorado since a magnitude 5.7 was recorded in 1973. That quake was centred in the north-western part of the state.
A spokesman from the Las Animas county sheriff's office said a few homes had been damaged in the quake and officials were investigating reports of rockslides along a road.
