Following a magnitude 7.1 earthquake on 19 September, International SOS and Control Risks are advising members in the capital Mexico City and Mexico, Morelos, and Puebla states to exercise caution, follow all official directives, plan journeys accounting for disruption and implement recommended health precautions.

The earthquake has resulted in loss of lives and caused major damage throughout Mexico City and areas nearby including damage to buildings, electricity and telephone network outages. Aftershocks of varying magnitudes could pose a risk to life and property and cause further damage to already weakened structures.

Travel advice

- Expect damage and disruption; follow all official directives, including health and security. Carefully consider the need to journey to affected areas. Members should liaise closely with local sources prior to making a decision to travel and balance the need against the impact of any natural hazard event.
- Travel in affected areas should only be undertaken with careful a risk assessment and forward planning, which should cater for a likely shortage of power and some basic supplies, accommodation and transportation as well as communication difficulties. Travellers should aim to be self-sufficient and should ensure that they have back-up communications systems in place should landline/mobile/internet networks fail.
- Roads may be blocked or subject to closure by the authorities with little or no notice. Reconfirm the status of routes and ensure that your vehicle is appropriate for the terrain.
- Avoid re-entering damaged structures.
- Localised travel disruption is possible. Liaise with local contacts and reconfirm status of routes before setting out.
