Back in July, an earthquake rocked Metro Manila. Unbeknownst to most but noticed by some, a globally renowned company was helping everyone through the natural incident: Google. In the few minutes leading up to and during the 6.7 magnitude earthquake, Android users received important alerts warning them of the ongoing tremors. Though it wasn’t the dreaded Big One, the alert afforded attentive users a few precious seconds to either seek appropriate cover or stop doing dangerous tasks.

Incidentally, the tech surrounding Google’s earthquake alert system wasn’t just hastily built on ongoing databases or social media. Google actually packed in a fully responsive earthquake sensor for Android phones.

Faster than an earthquake

The forever-increasing speed of technology has always been a contentious element since the rise of smartphones. Developers and users alike have wondered how accurate or quick our favorite devices can warn us of things happening around us. There’s even an XKCD comic about how Twitter can warn us of an earthquake minutes before it reaches the reader.

Over the years, technology has developed new ways to deliver alerts. From simple weather apps to city-wide messaging systems, users can receive warnings in a timely fashion. Practically nothing is a surprise anymore with the right technology.

That said, Google has successfully developed a new system that can rely on other Android smartphones to accurately tell whether or not an earthquake is happening.

A quake detector in your pocket

Speaking to Android Police, the feature’s lead engineer Marc Stogaitis described how Google’s earthquake sensor leveraged other devices to tell users about the quake. It all revolves around the different sensors built inside your phone.

As it is, every smartphone comes with a host of sensors to support its different functions. A light detector can seamlessly adjust brightness and camera settings, and a gyroscope can support compasses, for example. With earthquakes, the biggest element to ponder on is a smartphone’s movement and vibrations during an earthquake.

According to the lead engineer, figuring out the metrics for detecting an earthquake wasn’t a problem. After decades of accurate seismograph technology, developers already have an idea on what they need to measure.

However, the technology does not stop there. Naturally, there are hiccups to relying on just a single (or even every) phone’s data. For one, a city-wide messaging system can set off everyone’s phone in a single area, potentially causing false positives. Plus, relying on a single phone is definitely tricky. There are multiple actions which can cause vibrations akin to an earthquake.

Crowdsourcing a quake

The feature doesn’t rely on just one phone. It doesn’t tap into every Android phone in an area either. Instead, it collates data from phones plugged into a charger. Naturally, a plugged-in phone is the most reliable barometer in terms of battery reliability. They won’t die out in the middle of an earthquake and ruin a source of data. Additionally, charging phones are often stationary. They won’t be affected by motions that mimic earthquakes.

Google “listens” to charging devices in an area. If the subset meets the criteria for an earthquake, the company quickly determines the earthquake’s epicenter (based on approximate location) and magnitude. Once the system declares that a quake is indeed happening, it sends out an alert to nearby devices and gives them the time needed to seek shelter.

The alerts naturally prioritize people nearer to the epicenter. But, of course, the speed will ultimately depend on the phone’s connectivity. A phone hooked up to a building’s fast Wi-Fi connection will receive alerts faster than a commuter’s phone on data while going through a tunnel.

Still, the short time that the alerts give users is enough to save themselves from a precarious situation. Though the feature can potentially warn users of quakes minutes in advance, Stogaitis says that it will more realistically push alerts five to ten seconds before the incident. However, five seconds is enough to go under a table and have some sort of protection against falling debris.

Still keeping things private

For anyone worrying about how Google is handling their data, Stogaitis says that the company removes all identifiers from the data except for approximate location. And, despite that, Google still maintains that the feature will be the most accurate that it can be. Either way, the feature will be useful for any earthquakes in the future.

The earthquake sensor is available for any Android phone running Lollipop and above. Naturally, the feature still necessitates that users turn on emergency alerts on their phone.

WhatsApp will let you hide all your secret chats with a password

Passwords can even have an emoji

Secret chats is a boon to the online community. However, while the feature can protect your conversations from online snoopers, nothing can stop anyone who grabs your phone and goes through all your apps. Now, WhatsApp is finally adding an extra layer of protections for those who use secret chats on the platform — a secret code.

For anyone engaged in secret conversations, a password seems like a no-brainer. While the feature has been a long time coming, its launch is still welcome today. With the new version, users can hide all their secret chats with a passcode.

Plus, the passcodes are more unique than most. Rather than just a short PIN or a traditional password, users can use emojis too. Allowing emojis can add an even more secure lock to those private conversations.

Once secured, the locked chats will no longer pop up by default on WhatsApp’s main feed. While users can still toggle their visibility on and off, users will have to input their secret passcodes into the app’s search bar to see their list of secret chats.

While the feature is still rolling out now, users already have existing options to lock individual chats away from prying eyes. These measures include fingerprint scanning, face recognition, and good ol’ passwords. The new feature is more meant to hide all of them at the same time, especially when a shoulder snooper can just spot locked chats right from the list.

Google Messages adds new features similar to iMessage

Photomoji sounds familiar

It’s been a great month for RCS. Recently, Apple, the messaging standard’s longstanding rival, finally announced support for RCS coming in 2024. Now, it has reached another huge milestone: 1 billion active users, according to Google. To celebrate, Google has announced new features coming to Messages.

RCS has been the standard for Google’s Messages for a while now. However, despite reaching a significant number of users over the years, Messages has often trailed Apple’s iMessage in terms of features. Today, Messages is finally getting a healthy infusion of the latter’s newer developments.

For one, the new Photomoji feature can turn your photos into message reactions. Using the onboard AI, Google can automatically turn the subject of any photo for use in the app. Messages will also save these for future use. Now, while this might sound familiar for iOS users, Google will not require users to turn photos into stickers before using them in iMessage.

Users can also change the color of their bubbles, digging at the ongoing green versus blue debate between iOS and Android.

Additionally, Voice Moods will allow users to add an emoji to sent voice messages. Even before playing them, recipients will already have an idea what the tone of the message will be. And speaking of the format, Google also improved the audio quality for voice messages.

Finally, Messages will have Screen Effects going forward. Like other messaging platforms (like Messenger and Viber), typing certain phrases such as “I love you” will cause the screen to react appropriately. In Viber, for example, typing “happy birthday” will cause balloons to fly up from the bottom.

These updates are slowly rolling out through a beta version coming to select countries and devices.
