The rest of the country felt the quake but no major damages are reported. Regions like Guanacaste and the Pacific Coast in Costa Rica felt the quake but it was not felt as strong as it was felt in San Jose, Heredia and Alajuela. The Juan Santamaria Intl Airport is working fine and there are no damages reported. The Liberia Airport is working normally and had no damages.
If you are planning to come to Costa Rica, you just need to know that you will not be able to visit the Poas Volcano and any of the attractions close by since this area is chaotic at this time. The rest of the country is fine and there are no major damages and no more earthquakes are expected from this incident.
