Two large earthquakes have struck western Mexico within hours, shaking buildings as far away as the capital and sending people rushing out of offices on to the streets.
The first, in the western state of Michoacan had a magnitude of 6.5, at a depth of 20km, on Wednesday, Reuters reports.
The second quake, off Baja California, early on Thursday was stronger at a magnitude of 6.9 and shallower at a depth of 10km.
There are no reports of casualties or serious damage.
A 7.4 magnitude quake struck on 20 March, damaging hundreds of buildings in the southwest. That was followed by dozens of aftershocks.
