California is earthquake country, and residents of Los Angeles can now get some critical warning, when conditions are right, after a quake has started and seismic waves are heading their way.
The long-delayed system, called ShakeAlertLA, is the first of its kind in the United States.
Earthquake alert systems like this save lives, said Jeff Gorell, deputy Los Angeles mayor for public safety, as he demonstrated the application on his smartphone.
“When an earthquake starts, the first waves that go out are called P-waves,” he said. They serve as a warning and “are not the damaging, destructive waves” that will follow.
The alert system, which relies on data from seismic sensors throughout the region, could offer up to 90 seconds of warning for quakes of magnitude 5 or larger.
Even a few seconds can make a difference, said Los Angeles Mayor Eric Garcetti, as he rolled out the ShakeAlertLA smartphone app in January. Alerts let people know to drop, cover and hold on, as they are instructed to do in earthquakes.
Mexico City system
An alert system is in place in Mexico City that let residents brace for a mild shaker in early February after an earthquake struck Chiapas to the south. The quake was barely felt in the capital, but residents were ready.
The system doesn’t always help, however, and it did not with the magnitude 7.1 earthquake on Sept. 19, 2017, that killed hundreds in and around the Mexican capital. The quake’s epicenter was too close to offer warning.
Distance to epicenter crucial
Alert systems work when there’s enough distance between the earthquake’s epicenter and a center of population, said Thomas Heaton, professor of engineering seismology at the California Institute of Technology (Caltech).
“So, if you can recognize that an earthquake has started … you can give some area that’s about to be shaken strongly a heads up that says, ‘There’s an ongoing earthquake, and oh, by the way, it’s headed in your direction.’”
California is riddled with geological fault lines that periodically rupture. The largest, the San Andreas Fault, can give rise to massive temblors, including the San Francisco quake in 1906, which may have killed 3,000, according to later estimates.
A section of the same fault shifted in 1989, causing a magnitude 6.9 earthquake that killed more than 60 in Oakland and nearby communities. Smaller fault lines can also cause large temblors, including a previously unknown fault beneath the Northridge section of Los Angeles, where a magnitude 6.7 quake killed more than 60 people in 1994.
The ShakeAlertLA app offers users critical information after a temblor has started, said Deputy Mayor Gorell, “just enough so that they can digest it and then react to it, without overwhelming them with information or frightening them,” he said.
Advanced alert systems are also in place in Japan, and while the systems have limitations, authorities there say they have saved lives.
Los Angeles officials say preparing for earthquakes requires work on many fronts, including encouraging residents to prepare disaster plans and stock emergency supplies.
Preparations also require upgrades to old buildings. Los Angeles now has nearly 13,000 so-called soft-story buildings, with wide windows or doors on lower floors that need bracing. These buildings are vulnerable to damage or collapse if struck by seismic waves of a certain type or intensity.
Nearly 1,700 buildings have been upgraded to modern earthquake standards, and another 3,500 have been issued permits for retrofitting. It’s a race against time, officials say, because massive shakers rock the region periodically. The last big quake in Southern California, in 1857, reached magnitude 7.9, and could have killed thousands in a modern city.
The alert app can help, said Heaton, who noted that when the ground “starts to shake, you have no idea whether it’s going to get bigger, or whether it will stay small. Usually it stays small,” he said, “but you don’t know.”
Heaton said the system will give you an indication of what to expect, and also let emergency workers know where to send help after a quake has struck.
ShakeAlertLA is being rolled out in phases in the U.S. West coast states of California, Oregon and Washington, which are all vulnerable to earthquakes. (VOA)

The festive season is a time of joy. Some people truly love it, but for many, it can trigger feelings of loneliness and anxiety. Feeling lonely is common and completely normal -- whether or not we're living through this pandemic. The social pressure to "be happy" can be relentless, but it is important to take a proactive approach to meet not only our emotional needs but also to maintain our mental stability and well-being. With the pandemic, holidays are likely to be challenging, instead, meet them head-on with a renewed dedication and a proactive mindset to avoid 'holiday blues'.
Kanchan Rai, Mental and Emotional Well-being Coach, Founder, Let Us Talk, mentions ways to turn your loneliness into action this season:
Say yes to socializing: When we are experiencing loneliness, it can be easy to slip into the habit of saying no to social activities. Seclusion can make it challenging to feel driven and the mere thought of physically seeing people can lead to stress. Hence it is recommended to saying yes to mingling to help build your confidence. Something as simple as going for a walk with a friend or chatting with your loved ones over the phone can make a huge difference.

Devote your time to others: An effective way to beat loneliness amidst the holidays is by helping others who are less fortunate. The good cause will remind you of all you have to be appreciative for. This will help you to be a part of something larger, thus immersing yourself in the true spirit of the holiday season.

Make the most of technology: For those with distant loved ones, technology can prove to be an enabler in helping to keep family traditions alive. For instance, celebrate the festive cheer virtually or opening festive gifts on video calls amidst all family members. Taking a moment to network with someone, communicating about shared interests or fond memories, even if it's online, can play a major role in reminding us of the good times.

Get distracted with healthy coping strategies: Distraction can be useful when it's done with the intention of proactively giving yourself a break. For instance, it is recommended to watch a movie to take your mind off stressful thoughts instead of drinking many glasses of wine to forget aloofness. Taking a break will help prevent burnout and will enable you to deal with problems better.

Don't be afraid to speak up: Confiding in reliable friends or relatives about how you feel can often lift the weight off your shoulders, thus making you feel less isolated. It can also be helpful to consult your counsellor if the seasonal isolation has been impacting your emotional well-being. Counselling can help in building your confidence and will facilitate you to discover coping strategies to process any issue. (IANS/ MBI)

Ahead of the Windows 11 launch, Microsoft is rolling out some updates to Edge that include the addition of tab groups. Users will be able to assemble collections of tabs to make their browser a little less chaotic.
To create a group, hold the control button and choose the tabs you want to include, then select "Add tabs to new group" from the right-click menu, Engadget reported on Friday. Users can customise the label with a different colour for each group. When users hover over a tab, they will be able to see a preview of the web page as well.
Microsoft Edge is also getting some handy shopping features, the report said. The browser can give swift access to reviews and ratings for more than 5 million products. When users are on a product page, they can click the blue tag on the address bar and see expert reviews from reliable sources, as well as the average consumer star rating from various retailers.
When they do figure out what to buy, Microsoft aims to help them complete the transaction a bit faster. The new personalised news feed called Microsoft Start is integrated into the browser. Users will see headlines and articles relevant to their interests from a range of publishers when they open a new tab. (IANS/ MBI)
