Google warned millions before Venezuela quake: Can your Android phone save lives during earthquakes?

Google’s Android Earthquake Alerts System sent warnings to users before strong earthquakes hit Venezuela. Here’s how the smartphone-based early warning technology works.

Millions of Android users in Venezuela reportedly received earthquake alerts on their smartphones moments before powerful tremors shook the country, renewing global interest in how Google’s earthquake warning technology functions and whether smartphones can help save lives during natural disasters.

The alerts were triggered ahead of the strong shaking caused by the powerful earthquakes that struck Venezuela this week. However, experts have clarified that Google did not predict the earthquakes. Instead, the company’s system detected the initial seismic activity and rapidly issued warnings to people located in potentially affected areas.

How Google’s Android Earthquake Alerts System works

Google’s Android Earthquake Alerts System uses the accelerometers built into billions of Android smartphones. These sensors, typically used to detect device movement and screen orientation, can also identify ground vibrations associated with earthquakes.

When multiple Android devices in the same region detect similar vibrations simultaneously, anonymised data is sent to Google’s servers. Algorithms then analyse the information to estimate the earthquake’s location, magnitude and expected intensity. If the system determines that significant shaking is likely, alerts are automatically sent to users in affected areas.

The technology works by detecting primary seismic waves, or P-waves, which travel faster and are generally less destructive than secondary waves, known as S-waves. Since internet signals travel much faster than seismic waves, alerts can reach users seconds before the strongest shaking arrives.

Why a few seconds can make a difference

Although the warning window is often brief, experts say even a few seconds can be crucial during an earthquake. Such alerts can allow people to move away from hazardous areas, stop dangerous activities, seek cover or prepare for stronger shaking.

During the recent earthquakes in Venezuela, some residents reported receiving alerts on their phones shortly before the tremors intensified, giving them additional time to react.

How to enable earthquake alerts on Android

Google says Android earthquake alerts are available in many countries, including India. To receive these notifications, users need an Android device running Android 5 or later, active internet connectivity and location services enabled.

To check whether earthquake alerts are enabled:

  1. Open Settings on your Android smartphone.
  2. Search for “Earthquake alerts”.
  3. Ensure the feature is turned on.
  4. Keep both location services and mobile data or Wi-Fi enabled.

Google emphasises that the system is designed as a supplemental early warning service and may not detect or alert users about every earthquake. It does not predict earthquakes before they begin but aims to provide precious seconds of advance warning once seismic activity is detected.

Uniform rules for WhatsApp, Telegram under review as Centre examines legal aspects

The Centre is reviewing responses from WhatsApp, Telegram and Zoho Bharat Eye over username-based messaging features, with a notification on uniform rules likely within 20 days.

The Centre is reviewing responses submitted by WhatsApp, Telegram and Zoho Bharat Eye regarding their username-based messaging features, as the government evaluates whether regulatory action is required. A notification on the issue could be issued within the next 20 days.

MeitY examines responses from messaging platforms

According to sources in the Ministry of Electronics and Information Technology (MeitY), WhatsApp, Telegram and Zoho Bharat Eye have responded to government notices concerning username-based messaging features.

The ministry’s legal team is scrutinising the replies to determine whether any existing legal provisions have been violated and whether any clauses can be invoked for regulatory action or sanctions.

Speaking on the sidelines of the launch of a cybersecurity report on Monday, MeitY Secretary S. Krishnan confirmed that WhatsApp’s response had been received over the weekend and is currently under examination.

“The reply was received last week. We are examining the response and action, if any, will be taken after that examination,” he said.

Government stresses uniform regulatory approach

The government has maintained that any regulatory framework introduced in connection with username-based messaging will apply equally across all messaging platforms rather than targeting any single service.

Union Minister Ashwini Vaishnaw has indicated that a notification on the matter is expected within the next 20 days. The ongoing review is focused on examining the legal implications rather than being a purely policy exercise.

Why the government raised concerns

MeitY had issued notices to WhatsApp, Telegram and Signal after expressing concerns that username-based messaging, which allows users to communicate without sharing their phone numbers, could be misused for impersonation, phishing, identity theft and so-called “digital arrest” scams.

Earlier, a WhatsApp spokesperson said the platform is primarily designed as a private messaging service that helps people stay connected with friends and family.

The review forms part of the government’s broader efforts to strengthen online safety, curb the misuse of digital communication platforms and ensure that any future regulations are implemented uniformly across messaging services.

Xbox announces 3,200 layoffs as Asha Sharma outlines major restructuring plan

Xbox has announced plans to lay off 3,200 employees over the next year while introducing a major restructuring programme that includes management changes, studio restructuring and cost-cutting measures.

XBOX layoff

Xbox has announced plans to reduce its workforce by 3,200 employees, representing around 20 per cent of its total staff, over the coming year as part of a broader restructuring programme linked to Microsoft’s increased investment in artificial intelligence.

According to an email shared with employees by Asha Sharma, the company will begin the process immediately, with 1,600 employees leaving on Monday, while the remaining job reductions will take place during FY27. The company also plans to divest four gaming studios and is preparing to separate from another.

Business reset planned amid financial challenges

In her message to employees, Sharma said the company’s current financial position required significant changes, stating that Xbox’s business was operating at substantially lower margins than comparable platform and publishing companies.

She said the layoffs were not a reflection of employees’ commitment or abilities but were part of a wider effort to strengthen the company’s long-term business.

The workforce reduction comes as Microsoft continues implementing AI-focused cost-cutting measures across its operations. Overall, the technology company is reportedly cutting 4,800 jobs, with Xbox accounting for the largest share.

Sharma also described the gaming sector as experiencing one of its most challenging hardware periods and said the company needed to “reset Xbox” to improve its future performance.

Company to streamline operations and reduce management layers

As part of the restructuring strategy, Xbox plans to simplify its organisational structure, revise its content portfolio and improve platform operations.

According to Sharma, the company currently loses 64 cents for every dollar invested annually, making operational efficiency a key priority.

She said Xbox would increasingly support independent game creators by offering open development tools and broader audience access.

The restructuring will also see Mojang and King report directly to Sharma. She said both studios have evolved into major gaming platforms with large monthly active player bases and will play a central role in Xbox’s future strategy.

To improve decision-making, the company plans to significantly reduce its management hierarchy. Sharma said some departments currently have as many as 14 management layers, which slow down operations. Xbox aims to reduce this to no more than five layers, and in some cases, only three.

The company will also reduce vendor spending by 50 per cent as part of its cost-saving measures.

Helen Chiang promoted to Chief Operating Officer

Alongside the restructuring announcement, Sharma confirmed the promotion of Helen Chiang to the newly created position of Chief Operating Officer.

Chiang will oversee profit and loss responsibilities across Xbox’s content, hardware, platform and services divisions while reporting directly to Sharma.

According to Sharma, the new operating structure is intended to improve investment decisions, strengthen accountability and better integrate the company’s various business units.

Despite the ongoing restructuring and job cuts, Sharma said Xbox remains committed to long-term growth and plans to continue investing heavily in the business, while placing greater emphasis on disciplined spending and strategic priorities.

WhatsApp gets more time to respond on username feature, rollout in India put on hold

WhatsApp has been granted more time to respond to the government’s concerns over its username feature and has assured that it will not launch the feature in India until discussions are completed.

Meta assures the government that the feature will not be introduced in India until ongoing consultations are completed.

Meta-owned WhatsApp has been granted an extension to submit its response to the Centre regarding its proposed username feature, while assuring the government that it will not roll out the feature in India until discussions on the matter are concluded.

According to sources, the government has allowed WhatsApp three additional days to file its response after the company sought more time. The original deadline for the reply was Friday.

The proposed username feature would allow users to connect with others without revealing their phone numbers, a move that has raised concerns within the government over its potential impact on cyber safety.

Last week, the Centre issued a notice to Meta questioning the feature, expressing concerns that it could increase online fraud, phishing attempts, impersonation, and so-called “digital arrest” scams. The government also directed the company to pause the rollout until consultations are completed to its satisfaction.

Sources said representatives from Meta met officials from the Ministry of Electronics and Information Technology (MeitY) on Friday following the issuance of the notice. During the discussions, WhatsApp reportedly assured authorities that the feature would not be introduced in India before the consultation process is completed.

The government has also asked Meta to explain why action should not be initiated under the Information Technology Act and the relevant rules if the proposed feature is found to compromise user safety. It reminded the company that WhatsApp, as a significant social media intermediary, must comply with due diligence obligations under Indian law.

A WhatsApp spokesperson had earlier clarified that the username feature is not yet live and is expected to be introduced gradually later this year.

The company said it has built several safeguards into the feature to prevent impersonation. According to WhatsApp, usernames of public figures, government entities, celebrities, and verified Meta accounts have been reserved so that they can only be claimed by their legitimate owners. It also said lookalike variations of such usernames are being restricted.

WhatsApp also clarified that users will still need a phone number to create and use a WhatsApp account. The username feature is intended only as an alternative way for people to connect.

The company added that users would need to know another person’s exact username before initiating contact. It also plans to limit how many new users an account can message, prevent repeated attempts to guess usernames, and use automated systems to detect impersonation and abusive behaviour.

To help users identify unfamiliar contacts, WhatsApp said it will display contextual information whenever someone sends a message through a username for the first time. Users will be informed whether the sender is a new account, an existing contact, someone who shares a mutual group, or a person located in another country before deciding whether to respond.

Following its notice to WhatsApp, the IT Ministry also issued notices to Telegram and Signal, seeking details on how their existing username-based systems address concerns related to fraud and impersonation. While WhatsApp has around 500 million users in India, Telegram has a significantly smaller user base.

In recent days, Meta and Telegram have also come under regulatory scrutiny on separate issues. The government recently issued a notice to Meta regarding child sexual abuse material appearing in Instagram advertisements, while Telegram was directed to strengthen action against the circulation of pirated films, OTT content, and other copyrighted audio-visual material on its platform.
