The strong earthquakes that shook central and southwest Mexico September 2017 (one on the 7th and another on 19th) have brought out a real strength and solidarity in the country's people. This has been visible not only in terms of the waves of volunteers who have taken to the streets of the capital to remove debris and donate supplies, but also in terms of netizens capturing and sharing images from an event that has left the country in shock.

Several people collaborated on a collection of photos documenting the devastation and subsequent aid effort. Among them are photographer Santiago Arau and mountain climber Raul Morales.

Arau has shared numerous photos via Instagram, also left photos for those who wish to use them through the site WeTransfer. Raúl Morales has shared the images through Google.

Below Global Voices reviews some of the most evocative and representative images captured by the pair.

In this photo taken during the first hours of the disaster, Raúl Morales shows civilian volunteers along with members of Mexico’s Navy starting rescue work at a collapsed building .

Day and night the rescue work was carried out at the destroyed buildings, as shown in this image of a property in the south of Mexico City.

The material destruction has still not been quantified yet. Not only are homes effected, but also hundreds of automobiles.

“Anonymous Heroes”, is perhaps the best way to describe the citizens who took responsibility for starting rescue work after the tragedy.

This image gives us an idea of the sea of people that came to the collapsed zones, the majority with the intention of helping, others just as spectators, but all sharing hurt and shock over the scenes they were witnessing.
