In the eyes of the world, Mexico has been one of the countries that has suffered the natural phenomenon of an earthquake on a larger scale.

An investigation by Become Atlas reflects that between the years 1900 and 2016, Mexico ranked number 9 along with Afghanistan, India and Greece among the countries most prone to earthquakes.

These natural phenomena, which affect populations around the world, have inspired the development of technologies that detect earthquakes, prevent tragedies, and help victims.

In addition to transferring information at high speed, optical fiber serves to detect movements on the ground, according to Berkeley National Laboratory in California.

The cables send out pulses of light with data along the plastic fibers of the cables and if there are any imperfections in the filaments of these, a little light travel back to the source.

It is thanks to this phenomenon that researchers can detect and study the damage that seismic waves create in the fibers and thus alert about seismic activity.

In 40 seconds, this module with motion sensors detects the onset of an earthquake and connects to a GPS system for detect the epicenter of the earthquake and predict its magnitude.

The tool, called Geodetic First Approximation of Size and Timing (G-FAST) was developed in Washington, USA and has been used mainly in Chile to predict seismic activities.

In 2018, a group of researchers from the American Chemical Society developed a portable device capable of “Smell” and locate people buried under rubble after an earthquake.

The device has three sensors highly sensitive to acetone, ammonia and isoprene, which are also metabolic products that the body emits through the breath and the skin.

The best thing about this gadget is that “it is small and inexpensive,” according to the professor. Sotiris Pratsinis, who leads the group of researchers.

Anti-earthquake bricks

This is a invention of Spanish origin that has generated acceptance in different countries and is known as seismic brick or self-centering brick.

Each block has has 2 holes at the top, 6 steel rods at the bottom that connect to the holes in the brick below (as if they were LEGO pieces) and 4 legs that separate them at the correct distance.

The design increases the strength of the bricks and makes it difficult for them to be knocked over in accidents or earthquakes.

Survival capsule

This is an invention 100% Mexican, created by the engineer Reynaldo Vela.

The Chapter K 107, made of titanium powder alloys with steel, it has a parallelepiped (or egg) shape as it is one of the most stable and impact resistant geometric figures.

Inside the capsule, users will find a refrigerator, a drinking water system, an oxygen tank and a GPS system.
