Scientists predict serious earthquakes in the Himalayas

January 1, 2013

Singapore, Jan 1: Scientists have warned of more great earthquakes — of the magnitude 8 to 8.5 — in the Himalayas, especially in areas with their surface yet to be broken by a temblor.

A research team led by Nanyang Technological University (NTU) has discovered that massive earthquakes in the range of 8 to 8.5 magnitudes on the Richter scale have left clear ground scars in the central Himalayas.

This ground-breaking discovery has huge implications for the area along the front of the Himalayan Mountains, researchers said in a statement.

Paul Tapponnier, a leading neotectonics scientist, said that the existence of such devastating quakes in the past means that quakes of the same magnitude could happen again in the region in future, especially in areas which have yet to have their surface broken by a temblor.

The study showed that in 1255 and 1934, two great earthquakes ruptured the surface of the earth in the Himalayas. This runs contrary to what scientists have previously thought.

Massive earthquakes are not unknown in the Himalayas, as quakes in 1897, 1905, 1934 and 1950 all had magnitudes between 7.8 and 8.9, each causing tremendous damage. But they were previously thought not to have broken the earth"s surface - classified as blind quakes - which are much more difficult to track.himalayas

However, Mr. Tapponnier said that by combining new high resolution imagery and state-of-the-art dating techniques, they could show that the 1934 earthquake did indeed rupture the surface, breaking the ground over a length of more than 150 kilometres, essentially south of the part of the range that harbours Mount Everest.

This break formed along the main fault in Nepal that currently marks the boundary between the Indian and Asian tectonic plates - also known as the Main Frontal Thrust (MFT) fault.

Using radiocarbon dating of offset river sediments and collapsed hill-slope deposits, the researchers managed to separate several episodes of tectonic movement on this major fault and pin the dates of the two quakes, about 7 centuries apart.

Mr. Tapponnier warns that the long interval between the two recently discovered earthquake ruptures does not mean people should be complacent, thinking that there is still time before the next major earthquake happens in the region.

In a bid to help struggling small businesses in Covid-19 times, Facebook has introduced Shops to help set up a single online store for customers to access on both Facebook and Instagram.

While Facebook Shops is being rolled out from Wednesday, the company will introduce Instagram Shop, a new way to discover and buy products in Instagram Explore, this summer, starting in the US.

The social networking giant also announced that it will invest in features across its family of apps to inspire people to shop and make buying and selling online easier.

"Creating a Facebook Shop is free and simple. Businesses can choose the products they want to feature from their catalogue and then customise the look and feel of their shop with a cover image and accent colours that showcase their brand," Facebook said in a statement late Tuesday.

Any seller, no matter their size or budget, can bring their business online and connect with customers wherever and whenever it's convenient for them.

People can find Facebook Shops on a business' Facebook Page or Instagram profile, or discover them through stories or ads.

"From there, you can browse the full collection, save products you're interested in and place an order — either on the business' website or without leaving the app if the business has enabled checkout in the US," informed the company.

Last month, Facebook announced $40 million in grants for 10,000 small businesses in the US to help them get through these challenging time.

The grants will go to small businesses in 34 locations where Facebook employees live and work.

The company said that in Facebook Shops, users will be able to message a business through WhatsApp, Messenger or Instagram Direct to ask questions, get support, track deliveries and more.

In the future, they will be able to view a business' shop and make purchases right within a chat in WhatsApp, Messenger or Instagram Direct.

Later this year, Facebook will add a new shop tab in the navigation bar, so people can get to Instagram Shop in just one tap.

Facebook said it is making it easier to shop for products in real time.

Soon, sellers, brands and creators will be able to tag products from their Facebook Shop or catalogue before going live and those products will be shown at the bottom of the video so people can easily tap to learn more and purchase.

"We're starting to test this with businesses on Facebook and Instagram, and we'll roll it out more broadly in the coming months," said the company.

Facebook is also working with partners like Shopify, BigCommerce, WooCommerce, ChannelAdvisor, CedCommerce, Cafe24, Tienda Nube and Feedonomics to support small businesses.

Mumbai, Jun 12: Following an overwhelming response for the mega rights issue of Mukesh Ambani-owned Reliance Industries, the partly paid-up rights shares are set to debut on stock exchanges on June 15.

The biggest ever Rs 53,124 crore rights issue was subscribed 1.59 times and received bids worth Rs 84,000 crore on June 3.

Reliance said the rights issue saw a huge investor interest, including from lakhs of small investors and thousands of institutional investors, both Indian and foreign.

In 2019, Ambani said in the Reliance's annual general meeting that the company will be net zero debt by March 2021. The company is on course to achieve its target ahead of the deadline.

"In spite of the COVID-19 crisis and the lockdowns, the due-diligence by Saudi Aramco for the planned investment in the O2C business is on track as both the parties are committed and actively engaged," he said recently.

"With a strong visibility to these equity infusions, Reliance is set to achieve net zero debt status ahead of its own aggressive timeline. We believe rights issue was a part of the company's strategy of deleveraging its balance sheet," said Ambani.

Washington, Jan 7: Facebook will ban deepfake videos ahead of the US elections but the new policy will still allow heavily edited clips so long as they are parody or satire, the social media giant said Tuesday.

Deepfake videos are hyper-realistic doctored clips made using artificial intelligence or programs that have been designed to accurately fake real human movements.

In a blog published following a Washington Post report, Facebook said it would begin removing clips that were edited--beyond for clarity and quality--in ways that "aren't apparent to an average person" and could mislead people.

Clips would be removed if they were "the product of artificial intelligence or machine learning that merges, replaces or superimposes content onto a video, making it appear to be authentic," the statement from Facebook vice-president Monika Bickert said.

However, the statement added: "This policy does not extend to content that is parody or satire, or video that has been edited solely to omit or change the order of words."

US media noted the new guidelines would not cover videos such as the 2019 viral clip -- which was not a deepfake -- of House Speaker Nancy Pelosi that appeared to show her slurring her words.

Facebook also gave no indication on the number of people assigned to identify and take down the offending videos, but said videos failing to meet its usual guidelines would be removed, and those flagged clips would be reviewed by teams of third-party fact-checkers -- among them AFP.

The news agency has been paid by the social media giant to fact-check posts across 30 countries and 10 languages as part of a program starting in December 2016, and including more than 60 organisations.

Content labeled "false" is not always removed from newsfeeds but is downgraded so fewer people see it -- alongside a warning explaining why the post is misleading.
