Google has expanded its Android Earthquake Alerts System from 98 to more than 200 countries and regions, extending access to mobile-based earthquake warnings and introducing plans to provide users with more detailed information during seismic events. Announced on October 15, 2026, the expansion includes additional locations such as Panama and Guatemala. Google said the system has delivered more than one billion alerts since its launch in 2021, making it one of the largest mobile-based earthquake detection networks. The technology is designed to give people a few seconds of warning before significant shaking reaches their location, allowing them to take protective action when time is limited.
The system uses accelerometers built into Android smartphones to detect vibrations that may indicate an earthquake. When multiple devices in an area register similar movement, the system analyses the information to assess whether an earthquake is occurring and can distribute alerts to nearby users. This approach allows smartphones to contribute to earthquake detection in areas where conventional seismic monitoring infrastructure may be limited. Google says users in supported regions can receive one of three types of alerts, depending on the estimated shaking intensity. The “Be Aware” notification informs users that an earthquake has been detected nearby when light shaking is expected. The “Be Ready” alert warns of potentially stronger shaking and encourages users to prepare, while the full-screen “Take Action” alert provides immediate safety guidance when moderate to heavy shaking is anticipated.
Google is also preparing an update to the “Be Ready” notification that will provide additional information to help people understand an earthquake and respond appropriately. The planned improvements include a map showing the radius of detected shaking, an estimate of the earthquake’s magnitude, recommended safety actions and a button linking to further information as it becomes available. These additions are expected to roll out over the coming months. By placing more context directly within the alert, Google aims to help users assess the situation without relying solely on a brief notification. However, earthquake detection and warning systems cannot guarantee that every event will be detected or that every user will receive advance notice. The time available to respond can vary according to the earthquake’s location, the distance from the affected area and how quickly the event is identified.
The expansion highlights the growing role of consumer devices in disaster preparedness, with smartphones serving not only as communication tools but also as part of a distributed detection network. Google CEO Sundar Pichai has pointed to the system’s use during earthquakes in Venezuela, where people outside the epicenter reportedly received alerts before shaking reached them. Android earthquake alerts are available in Pakistan, although availability and delivery can depend on device settings, connectivity and regional support. Users can check the feature by opening their phone’s Settings and navigating to Safety and emergency, then Earthquake alerts. Google advises keeping Wi-Fi or mobile data enabled to receive alerts. The company’s latest expansion increases the system’s reach, while the planned improvements aim to make warnings more informative and useful during emergencies.
