Google Issues Apology After Earthquake False Alarm in Brazil

A technical glitch in Google's Android warning system mistakenly alerted users in São Paulo and Rio de Janeiro to a non-existent earthquake.

Google's Android earthquake alert system sent out a false alarm for a 5.5 magnitude earthquake near São Paulo early Friday morning.
The alert caused widespread concern, waking residents in São Paulo and Rio de Janeiro, though no seismic activity occurred.
Google has temporarily disabled the earthquake warning system in Brazil and is investigating the cause of the error.
The Brazilian Civil Defense confirmed that there were no earthquake-related incidents and denied the occurrence of any seismic event.
Google's system uses smartphone sensors to detect vibrations and send alerts, but the company clarified it is meant to complement, not replace, official warning systems.
