Khaberni - Despite Venezuela's lack of a national early warning system for earthquakes, millions of residents received warnings on their Android phones seconds before the seismic shocks that hit the country on Wednesday, June 27, 2026.
The New York Times launched its report with the story of Jose Flores, who was driving his car with his family in the capital, Caracas, heading to watch a movie when suddenly a loud alert from his wife's Android phone went off, and about 6 seconds later, he began to feel the ground shake.
Initially, Flores thought the uneven road was the cause of the vibration, a common occurrence in Venezuela, but when he saw the light poles swaying, he realized that a real earthquake had occurred, and it was the first time he and his family had received such an alert through Google's Earthquake Alerts system.
The newspaper reviewed how Google's Earthquake Alerts system works, stating that it relies on motion sensors built into Android phones to detect the primary earthquake waves and send the data to Google servers, where it is analyzed within seconds to determine the earthquake's location and intensity, and then send warnings to users in the affected areas.
According to Google, the alerts reached about 11.4 million people before two consecutive earthquakes of 7.2 and 7.5 magnitude occurred, while about 1.4 million people received the highest level of warning, reserved for areas expected to experience the most severe shaking.
The company explained that the system detected the primary seismic waves just 3 seconds after the earthquake began, and was able to confirm its occurrence and send the first alerts after another 6 seconds, before gradually expanding the range of warnings as more data flowed in from the phones.
The article noted that the system's effectiveness depends on the difference in speed between the seismic waves, as the less destructive primary waves precede the secondary waves responsible for most of the damage, giving residents, especially those far from the epicenter, additional seconds to take safety measures.
The system also relies on aggregating data received from a large number of fixed phones in the area, to reduce the chances of false alarms and improve the accuracy of locating the earthquake and its magnitude.
The report indicates that traditional government warning systems, used in countries like Japan, Mexico, Canada, and the United States, are based on networks of ground sensors, while Google's system provides an effective alternative for countries that do not have such infrastructure, benefiting from the widespread use of Android phones, which represent about 70% of smartphones globally.
The service was launched in 2021 in a limited number of countries, and expanded to include 98 countries by 2023.
The article concluded that it is still uncertain whether these warnings saved lives during the Venezuela earthquake, but experts confirm that a few seconds can be enough to give residents a chance to take shelter before the violent shakes arrive, which underscores the importance of early warning technologies based on smartphones in reducing the risks of natural disasters, especially in countries lacking advanced seismic monitoring systems.
