The Grillo (Spanish for Cricket) box aims to provide a low-cost, earthquake warning system for citizens in some of Mexico's biggest cities including Mexico City.

The device is the creation of inventor Andres Meira (pictured). It works by tapping into signals sent out by SASMEX, one of the most advanced seismic sensor systems in the world.

Meira created the Grillo device after moving to Mexico City with his family. The Mexican capital is particularly vulnerable to seismic activity given its proximity to major fault lines on the country's Pacific Coast.

Mexico City has endured devastating earthquakes over the years. A particularly strong quake flattened parts of the city in September, 1985.

Upwards of 10,000 people were killed during the 1985 quake, while hundreds of thousands of homes were damaged or destroyed.

The 1985 shock prompted the Mexican government to invest in the SASMEX early warning system, but many people still don't receive warnings because there are not enough receivers to broadcast them.

The Grillo box aims to change that and at $50 is less than one sixth of the price of current devices, which are mainly located in public buildings like schools and hospitals.

The Grillo Active is Meira's next big idea for earthquake early warning systems. Rather than rely on data from SASMEX, it will pick up seismic movement itself and send alerts to smartphones and specially designed apps.

Meira expects between 500 and 1,000 Grillo Active boxes to be placed close to fault lines and areas of interest around Mexico. Because the devices are cheap and are easy to produce, he believes the technology could easily be transferred to other parts of the world.
