Assam Earthquake

Relevance: Geography

Context: Several houses and buildings were damaged after an earthquake of magnitude 6.4 on the Richter scale hit Assam.

What is an earthquake?

  • An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. During an earthquake, vibrations caused by the breakage of rock along a fault zone radiate outward from the point of rupture. The instrument used to record and measure these vibrations is called a
  • The location below the earth’s surface where the earthquake starts is called the hypocentre, and the location directly above it on the surface of the earth is called the

What Causes Earthquakes?

  • Tectonic plates are constantly moving due to convection currents triggered by molten lava inside the earth’s crust. This constant movement leads to either the plates sliding against each other or drifting away from each other.
  • When these plates move against each other, there is a point where they interact this point is known as a fault line. This fault line is sometimes known as a fracture in the earth’s crust.
  • The moment the plates begin to move, the potential energy, commonly known as stored energy, is released from the hypocentre. The outcome is an earthquake.

Types of Earthquakes

  • Tectonic Earthquakes– The tectonic plates are capable of moving slowly and gradually. The movement of these plates occurs in different forms; towards each other, away from each other, sliding past each other or colliding with each other. A huge tremor occurs when 2 moving tectonic plates slide over one another. This type of earthquake is known as a tectonic earthquake.
  • Volcanic Earthquakes– These are less prevalent. They typically take place before or after an eruption.
  • Explosion Earthquakes– These are caused by nuclear explosions. They are, essentially, man triggered kinds of earthquakes and represent the biggest impact of modern-day nuclear war.
  • Collapse Earthquakes- They are sometimes referred to as mine bursts. Collapse earthquakes are instigated by the pressure generated within the rocks. This kind of earthquake leads to the collapse of the roof of the mine instigating more tremors.

What is the Richter scale?

  • The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
  • The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
  • Adjustments are included for the variation in the distance between the various seismographs and the epicentre of the earthquakes. On the Richter scale, magnitude is expressed in whole numbers and decimal fractions.
  • In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6.

Green Initiatives

Relevance: Environment

Context: Saudi Arabia has launched the Saudi Green Initiative and Middle East Green Initiative

About the Saudi Green Initiative

  • The Saudi Green Initiative aims to raise the vegetation cover, reduce carbon emissions, combat pollution and land degradation, and preserve marine life.
  • It aims to reduce carbon emissions by more than 4% of global contributions, through a renewable energy programme that will generate 50% of Saudi’s energy from renewables by 2030.
  • As part of the initiative, 10 billion trees will be planted in the Kingdom.
  • Saudi Arabia is working towards raising the percentage of its protected areas to more than 30% of its total land area, representing roughly 6,00,000 sq km, exceeding the global target of 17%.

 About Middle East Green Initiative

  • As part of the Middle East Green initiative, Saudi Arabia will work with the Gulf Cooperation Council countries and regional partners to plant an additional 40 billion trees in the West Asian region.
  • It represents 5% of the global target of planting one trillion trees and reducing 2.5% of global carbon levels.
  • Saudi Arabia will be sharing its expertise and know-how with its neighbouring countries to reduce carbon emissions resulting from hydrocarbon production in the region by 60% and globally by 10%.
  • The aim is to start implementing the plan in the fourth quarter of 2021 and continue for the next two decades.
  • Saudi Arabia will convene an annual summit called the Middle East Green Initiative which will host leaders from the government, scientists and environmentalists to discuss the details of implementation.
  • In partnership with participating countries, innovative methods will be researched to irrigate trees from treated water, cloud seeding and other purpose-driven solutions such as planting native trees which requires support for three years to grow and will then be able to survive on their own with natural irrigation.

About Gulf Cooperation Council (GCC)

  • The GCC was established by an agreement concluded on 25 May 1981 in Riyadh, Saudi Arabia.
  • The GCC is a political and economic union of Arab states bordering the Gulf. Its 6 members are the United Arab Emirates, Saudi Arabia, Qatar, Oman, Kuwait and Bahrain.
  • The GCC Headquarters are in Riyadh, Saudi Arabia.
  • The GCC Charter states that the basic objectives are to have coordination, integration and inter-connection between the Member States in all fields, strengthening ties between their peoples, formulating similar regulations in various fields such as economy, finance, trade, customs, tourism, etc.

Advanced Chaff Technology

Relevance: Science and Technology

Context: Defence Research and Development Organisation (DRDO) develops Advanced Chaff Technology to safeguard naval ships from missile attack.

About Advanced Chaff Technology

  • Chaff is an electronic countermeasure technology used by militaries worldwide to protect naval ships or other sensitive targets from radar and radio frequency (RF) guiding mechanisms of the enemy missile.
  • The chaff rockets deployed in the air reflect as multiple targets for the missile guidance systems and deflecting adversary missiles, thus protecting their assets.
  • Chaff is thin pieces of aluminium, metallized glass fibre or plastic, which either appears as a cluster of primary targets on radar screens or swamps the screen with multiple returns.
  • DRDO’s facility Defence Laboratory Jodhpur (DLJ) has indigenously developed three variants of this critical technology, namely Short Range Chaff Rocket (SRCR), Medium-Range Chaff Rocket (MRCR) and Long Range Chaff Rocket (LRCR).
  • A small quantity of chaff material, when deployed in the air, acts as a decoy and deflects the enemy’s missiles, thereby keeping India’s ships safe.

 Difference between chaff and flares:

  • Both chaff and flares are defensive countermeasures deployed by military aircraft. The purpose is to confuse radar-guided or infrared-guided anti-aircraft missiles fired so that they could be diverted.
  • Chaff is composed of much small aluminium or zinc coated fibres stored on-board the aircraft in tubes. In case the aircraft feels threatened by any radar tracking missiles, chaff is ejected into the turbulent wake of air behind the plane.
  • Flares however are useful in distracting the heat-seeking missiles. Mostly magnesium pellets are ejected from the tubes to ignite while being followed by an aircraft behind. The flares burn at more than 2000 Fahrenheit and emit high amounts of infrared light.

 About DRDO

  • DRDO is the R&D wing of the Ministry of Defence, with a vision to empower India with cutting-edge defence technologies and a mission to achieve self-reliance in critical defence technologies and systems, while equipping our armed forces with state-of-the-art weapon systems and equipment following requirements laid down by the three Services.
  • DRDO was formed in 1958 from the amalgamation of the then already functioning Technical Development Establishment (TDEs) of the Indian Army and the Directorate of Technical Development & Production (DTDP) with the Defence Science Organisation (DSO). Today, DRDO is a network of more than 50 laboratories.
  • DRDO is India’s largest research organisation. It has a network of laboratories engaged in developing defence technologies covering various fields, like aeronautics, armaments, electronics, land combat engineering, life sciences, materials, missiles, and naval systems.

Oxygen Concentrators

Relevance: Science and Technology

Context: PM CARES to fund 1 lakh portable oxygen concentrators.

What are Oxygen Concentrators?

  • An oxygen concentrator is a medical device that concentrates oxygen from ambient air. Atmospheric air has about 78 per cent nitrogen and 21 per cent oxygen, with other gases making up the remaining 1 per cent.
  • The oxygen concentrator takes in this air, filters it through a sieve, releases the nitrogen back into the air, and works on the remaining oxygen.
  • This oxygen, compressed and dispensed through a cannula, is 90-95 per cent pure. A pressure valve in concentrators helps regulate supply, ranging from 1-10 litres per minute.

How are concentrators different from oxygen cylinders and Liquid medical oxygen (LMO)?

  • Oxygen concentrators are the easiest alternatives to cylinders but can only supply 5-10 litres of oxygen per minute (critical patients may need 40-50 litres per minute) and are best suited for moderately ill patients.
  • Concentrators are portable and unlike LMO that need to be stored and transported in cryogenic tankers, need no special temperature. And unlike cylinders that require refilling, concentrators only need a power source to draw in ambient air.

About PM CARES Fund

  • The Prime Minister’s Citizen Assistance and Relief in Emergency Situations Fund were created on 28 March 2020, following the COVID-19 pandemic in India. The fund will be used for combat, and containment and relief efforts against the coronavirus outbreak and similar pandemic like situations in the future.

Breakthrough infections

Relevance: Health-related issues

Context: Breakthrough infections amongst fully vaccinated healthcare workers in Kerala is emerging as a new concern.

What are Breakthrough infections?

  • Vaccines are hailed to be the greatest weapons against the invisible enemy SARS-CoV-2 that causes COVID-19. However, there remains a bleak possibility that the virus may find a way to attack those who have already been inoculated. This scenario is known as ‘vaccine breakthrough infection’ where the pathogen infiltrates the immune response generated by the vaccines.
  • The chances of infection after full vaccination are relatively less. In India, just 0.04% of such re-infection cases have been reported so far, according to the country’s apex medical body the Indian Council of Medical Research (ICMR).

Why do breakthrough infections happen?

  • No vaccine is 100% effective against any viral disease. Hence, all types of vaccine, be it Moderna or Pfizer or Covaxin and have small chances of causing breakthrough infection. In addition, it must be noted that vaccines are a shield against severe forms of COVID-19 and not an infection. They reduce the chances of disease-related mortality and help patients recover fast.
  • It takes at least two weeks for vaccines to develop an immune response after getting the shots. Therefore, during this period, the chances of contracting the virus are equivalent to the person who has not received the shots.
  • There are also chances that the emerging mutant forms of the coronavirus may trigger infection again and evade the defence response induced by vaccines.

About ICMR

  • The Indian Council of Medical Research (ICMR), New Delhi, the apex body in India for the formulation, coordination and promotion of biomedical research, is one of the oldest medical research bodies in the world.
  • The ICMR is funded by the Ministry of Health & Family Welfare. The Council’s research priorities coincide with the National health priorities, such as control and management of communicable diseases, fertility control, maternal and child health, control of nutritional disorders, etc.
