Nov 18: A North Korean nuclear test in 2017 was so powerful that it moved the surface of Mount Mantap, the test location, as the explosion was 17 times more powerful than the bomb that destroyed Hiroshima, a team of researchers from the Indian space agency said.

The three-member team of Indian Space Research Organisation (ISRO) comprising K.M. Sreejith, Ritesh Agarwal and A.S. Rajawat has published their research paper in the Geophysical Journal International.

According to the researchers, the nuclear explosion resulted in sizeable surface deformation while the flanks of Mount Mantap experienced displacements of up to 0.5 metre along the line-of-sight of Japanese satellite ALOS-2.

Based on the satellite data, the researchers predicted that the explosion yield was about 245 to 271 kilotonnes as compared to the 15 kilotonne bomb used on Hiroshima in 1945.

As there were no seismic data, the researchers looked up to the skies to use the satellite data to measure the variations of the test site surface.

The researchers used the synthetic aperture radar (SAR) data from the Japanese satellite ALOS-2.

According to the researchers, the explosion test was done at a depth of 542 metre below Mount Mantap.

New Delhi, Mar 16: Due to the coronavirus pandemic, most airlines in the world will be bankrupt by the end of May and only a coordinated government and industry action right now can avoid the catastrophe, said global aviation consultancy firm CAPA in a note on Monday.

"As the impact of the coronavirus and multiple government travel reactions sweep through our world, many airlines have probably already been driven into technical bankruptcy, or are at least substantially in breach of debt covenants," it stated.

Across the world, airlines have announced drastic reduction in their operations in the wake of the coronavirus outbreak. For example, Atlanta-based Delta Air Lines stated on Sunday that it would be grounding 300 aircraft in its fleet and reduce flights by 40 per cent.

The US has suspended all tourist visas for people belonging to the European Union, the UK and Ireland. Similarly, the Indian government has suspended all tourist visas and e-visas granted on or before March 11.

CAPA, in its note on Monday, said, "By the end of May-2020, most airlines in the world will be bankrupt. Coordinated government and industry action is needed - now - if catastrophe is to be avoided."

Cash reserves are running down quickly as fleets are grounded and "what flights there are operate much less than half full", it added.

"Forward bookings are far outweighed by cancellations and each time there is a new government recommendation it is to discourage flying. Demand is drying up in ways that are completely unprecedented. Normality is not yet on the horizon," it said.

India's largest airline IndiGo -- which has around 260 planes in its fleet -- said on Thursday that it has seen a decline of 15-20 per cent in daily bookings in the last few days.

The low-cost carrier had stated that it expects its quarterly earnings to be materially impacted due to such decline.

CAPA said the failure to coordinate the future will result in protectionism and much less competition.

"The alternative does not bear thinking about. An unstructured and nationalistic outcome will not be survival of the fittest.

"It will mostly consist of airlines that are the biggest and the best-supported by their governments. The system will reek of nationalism. And it will not serve the needs of the 21st century world. That is not a prospect that any responsible government should be prepared to contemplate," the consultancy firm said.

Mumbai, Jun 3: With an expected increase in wind conditions up to 120 kilometres, cyclone Nisarga is likely to make landfall on the north coast of Maharashtra later today, as per the Indian Meteorological Department (IMD) on Wednesday.

"Wind conditions will further increase up to 100-110 gusting to 120 kmph as conditions are favourable for intensification. The higher sea surface temperature and low vertical wind shear favoured the intensification of severe cyclonic circulation," said IMD in a series of tweets.

Explaining the nature of wind speed, IMD further tweeted, "Eye diameter is about 65 km as observed through Radar. thus the diameter has decreased during past 01 hours indicating intensification of the system. hence wind speed has increased from 85-95 kmph to 90-100 kmph gusting to 110 kmph."

Several National Disaster Response Force (NDRF) teams have been deployed across Maharashtra to ensure preparedness for the impending cyclone. A total of eight teams have been deployed in Mumbai, five teams in Raigad, two teams in Palghar, Thane, and Ratnagiri and one team in Sindhudurg, said NDRF.

Besides, five NDRF teams were airlifted by IL-76 from Vijaywada for Mumbai on June 2, as per the Indian Air Force (IAF)

"Around 60 per cent of people, from the coastal areas around this area, have gone to their relatives' places. The remaining ones have been sent to the evacuation centre. We have also taken into account the COVID-19 guidelines and ensured social distancing," NDRF officer Shiv Parada Rao, deployed with his team in the Dahanu area, spoke to ANI.

"From the information we have received cyclone Nisarga is likely to hit here by tonight. The exact time is not confirmed yet. We are taking all preparedness measures to tackle the situation," he added.

NDRF teams also conducted evacuation in Alibaug during the early hours on Wednesday morning, as per NDRF Director General SN Pradhan.

As per the 5 am bulletin released by IMD, cyclone Nisarga was heading towards north Maharashtra coast at a speed of 11 kmph. It was about 200 km South -SouthWest of Alibag and about 250 km south-southwest of Mumbai at 2.30 AM today, stated the bulletin.
