The nearly 9 million people, officially dwell in Mexico City permanently, live daily with the likelihood of earthquakes of varying magnitude, given the seismically active zone where Mexico City is located. Although there is a vast early warning system, very few people that have the alarm device at home, especially since these devices are too expensive for the average income of the population. Today, Andy Meira, an amateur science and engineering, claims to have found the solution to this problem.
The year was 1985, when an earthquake shook the Federal District, claiming the lives of about 10 thousand people. Some years more afternoons at the beginning of the 1990s, the country established a sophisticated system capable of recording data from more than one hundred sensors distributed in the center and the west coast of Mexico, from Jalisco to Oaxaca, called System Mexican Seismic Alert. So, if tectonic danger, the system issues warning signs that the Government transmitted to the population through radio and television. Of course, the alarm can not reach those who are not found at that time in front of the television screen, or a radio speaker.
Therefore, soon after, also an instrument called SASMEX, a special receiver that is installed in homes and offices, and any alarm current replica was implemented. However, the device and its installation cost ranges from $ 1,300, expensive enough for most households and small businesses in the Mexican capital.
Andy Meira designed a device capable of using the signal transmitted by the SASMEX system that activates an audible and visual warning of seismic hazard, but it costs about 26 times less than the receiver 'official'. This important innovation called 'Grillo', has the size of a tennis ball, it can be sold for $ 50 and is easily installed.
Meira noted that the invention has proven effective when, in April 2014, alerted him and his family about an earthquake of 7.2 magnitude with its epicenter in the state of Guerrero, a half minutes before they began the first tremors. Through a public campaign in social networks, and the economic boost of a collaborative company, Meira managed to raise enough funds to build the first 175 devices.
