A moderate magnitude 5.2 earthquake has struck southern Mexico, the country's seismology service says, triggering alarms and evacuation procedures in the capital although there were no immediate reports of casualties.

The tremor, which was centred in the southwestern state of Guerrero, was felt lightly in Mexico City shortly after 9am local time on Wednesday and hundreds of people left office blocks and gathered in the streets. No damage was reported.

The country is still recovering from a pair of large earthquakes that caused widespread damage in September.

Wednesday's quake was originally measured as a 5.3 magnitude.
