Washington: Scientists have formulated a new algorithm to identify minor earthquakes which previously remained unknown the large ground motion measurement databases.

Even though microquakes are not life-threatening and don’t affect buildings or property much, their observation could help scientists better identify where bigger earthquakes could strike.


The algorithm, which is inspired by a popular song matching app called ‘Shazam’, is called Fingerprint and Similarity Thresholding, or FAST. Smaller quakes, which are not detected using conventional methods, and don’t even register as earthquakes, can be detected through this technology.

Waveform similarity was used extensively in seismology in the past decade through a process called template matching. This technique matches the seismic wave pattern of an earthquake to past recorded wave signatures in the database, explained Greg Beroza from Stanford School of Earth, Energy & Environmental Sciences.

However, to utilize this process, scientists need to know what signal they are looking for beforehand. The technique is also a time-consuming one.

Places such as Oklahoma and Arkansas could greatly benefit from this technology, as they have seen a rise in the number of minor quakes, which have been linked to hydraulic fracturing, or ‘fracking’. FAST could help properly identify risk areas.

The FAST technology needs to be tested over long time periods with a number of seismic stations to effectively predict when and where bigger quakes would strike.

The UK government on Thursday announced that it will move India from the red to the amber list on Sunday, in the country's latest update to the 'Red-Amber-Green' traffic light ratings for arrivals into England amid the Covid-19 pandemic.

This means the visit visas for the UK from India are open, in addition to other long-term visas that have remained open. But travellers from India arriving in England can complete a 10-day quarantine at home or in the place they are staying (not mandatorily quarantine in a managed hotel).

Pakistan has failed miserably to protect Hindus, their interests.

A Hindu temple in Pakistan's Punjab province was reportedly vandalized by hundreds of people after a nine-year-old Hindu boy, who allegedly urinated at a local seminary, received bail, a media report said on Thursday.

According to the Dawn news report, the incident took place on Wednesday in Bhong town, about 60 km from Rahim Yar Khan city.

Besides the vandalization, the mob also blocked the Sukkur-Multan Motorway (M-5), the report added.

Citing sources, Dawn news said that a case was registered against the minor on July 24 based on a complaint filed by a cleric, Hafiz Muhammad Ibrahim, of the Darul Uloom Arabia Taleemul Quran.

The sources said that "some Hindu elders did tender an apology to the seminary administration saying the accused was a minor and mentally challenged".

But, when a lower court granted him bail a few days ago, some people incited the public in the town on Wednesday and got all shops there closed in protest, the report quoted the sources as further saying.

A video clip showing people wielding clubs and rods storming the temple and smashing its glass doors, windows, lights, and damaging the ceiling fans went viral on social media.
