What Can We Do with Earthquake Early Warning?

Have you ever heard about the long-expected earthquake called “The Big One” and how to deal with the earthquake early warning? It is a hypothetical earthquake with a magnitude of 8.0 or higher, which is believed to happen in areas that have not been active for several decades in California. The scenarios of this earthquake forecast that it will occur near densely populated areas.

An earthquake of great magnitude, close to megalopolis, would be generating great intensities and increasing the probability of damage to basic infrastructure such as electricity, water, gas, communication routes, among others.

But there is good news: Quakes Alerts, better known as Earthquake Early Warning,  are systems that warn you before the quake strikes, with both devices for companies and apps for the public!


The history of earthquakes in the San Andreas Fault is remarkable and its consequences have been catastrophic, causing millionaire losses and numerous deaths. The most important earthquakes occurred in: 1608, of magnitude 7.7; 1857, of magnitude 7.9; 1906 (The Great San Francisco Earthquake), of magnitude 7.8M; 1989 (Loma Prieta, SF), of magnitude 6.9; 1994 (Northridge), of magnitude 6.7.

Those earthquakes happened with no early warning, but today if earthquakes with similar characteristics reoccur, we have the opportunity to foresee an earthquake coming thanks to notifications that quickly warn us.

Nowadays, millions of people live along the San Andreas Fault, even just a few feet away. The population density and large buildings, which did not exist in previous years, have shown that earthquakes, such as those occurred in 1989 and 1994, caused great damage and reminded us that the seismic hazard exists.

What can we do?

Quakes Alerts arrived to offer notifications seconds before the earthquake strikes. In recent years, hundreds of sensors have been placed near areas where significant earthquakes can occur; and those sensors are capable of detecting the first seismic waves, as well as assessing and predicting how strong the movement will be to issue warnings. With the new Earthquake Early Warning System, you will now have the ability to act seconds before feeling the shake, and you will be able to:

  • Know that an earthquake has already started.
  • Have time to “drop, cover and hold on”.
  • Close gas keys.
  • Pause delicate production processes.
  • Automatically open emergency exits.
  • Turn on electricity generators and emergency lights.
  • Warn your loved ones that an earthquake is on its way.

Quake Alerts were created to reduce economic losses and minimize the risk of disaster.

It is important to mention that an Earthquake Early Warning is not an earthquake prediction, but an alert system and that the warning time depends on how far you are from the epicenter.
