Grillo Sensor Performance

Grillo Sensor Network in Mexico

Grillo sensor nodes have been active in Mexico since 2017. You can see all the data here. This network is mainly distributed along the pacific coast where most earthquakes occur.

Here you can see the distribution of magnitudes that have been recorded, from 3.5M to a few M7s. The sensors were installed in rural villages, hotels, government buildings and schools and have been constantly transmitting data 24/7.

Earthquake Records

Surprisingly, the MEMs accelerometer featured in the Grillo and OpenEEW sensor nodes is very capable of capturing both large events and small events (>3.5M on average). Here you can see recordings taken from both a M7.4 and a M3.8:

In both cases the seismograms are clear and well defined.
