False Earthquake Alert Causes Panic in São Paulo and Rio de Janeiro
In the early hours of last Friday (14), residents of São Paulo and Rio de Janeiro were surprised by an earthquake alert sent to mobile devices with the Android system. The warning, which indicated a supposed tremor of magnitude 5.5 with an epicenter near Ubatuba, on the coast of São Paulo, caused panic and confusion among users. However, the alert was quickly denied by authorities and geological institutions.
The Android Earthquake Alert System, which uses sensors in phones to detect seismic activity, experienced a technical failure. The Civil Defense of São Paulo confirmed, through its official account on X (formerly Twitter), that there was no record of any seismic activity in the state. The Seismology Center of the University of São Paulo (USP) also corroborated the information, stating that no tremor was detected in the region.
Google, responsible for the Android system, apologized for the incident and informed that the alert system was temporarily disabled while the company evaluates the failure. The alert, which was triggered around 2 a.m., generated a wave of searches on Google, with terms like “earthquake near me” and “earthquake SP” registering peaks of interest.
Despite the scare, authorities reinforced that Brazil is located far from the edges of tectonic plates, making the occurrence of significant earthquakes extremely rare in the country. The incident served as a reminder of the importance of reliable notification systems and the need for continuous improvement of these technologies.
