1. Reasons behind seismic activity in Delhi:

  • The national capital has felt around 15 low-intensity earthquake tremors in the past two months
  • Many reports quoted some researchers who indicated that these tremors might be the pre-shocks to a big earthquake in the reason.
  • According to the seismic zone map, Delhi and its surrounding areas fall under zone 4, which is considered a high-risk seismic zone.
  • According to the experts Delhi is surrounded by fault lines like Dehradun-Mahendergarh fault and Delhi-Mathura fault situated in nearby areas so, the seismic activity around Delhi is quite frequent.
  • To keep a track of geological movements observatories have been set up all around the world.
  • India has a network of observatories under National Center for Seismology (NCS), Ministry of Earth Sciences, which collects seismic data round the clock.

Earthquake:

The tectonic plates present on our Earth are in a state of continuous motion.
So, when the two adjoining plates collide with each other or rub against each other, energy is generated in the form of waves or vibrations that are felt on the Earth, this is known as an Earthquake.
According to the scientific theory, the Himalayas were formed when the Indian tectonic plate collided with the Eurasian plate and slipped under it.
As per the seismology data, India is currently divided into 4 zones:
Zone 2, Zone 3, Zone 4, and Zone 5.
Zone 5 is considered the most vulnerable to earthquakes, which includes the Himalayan region.
Although Delhi and its surrounding areas are situated on the Indian plate there are no major fault lines in this area. So, the possibility of a big earthquake in Delhi is quite low.

 

2. AI-Powered diagnostic kit for Covid-19:

  • Indian researchers from IIT Hyderabad have come up with an innovative diagnostic kit to combat Covid-19.
  • The researchers have developed a quick and portable test kit powered by Artificial Intelligence. The kit will cost only Rs 350 per kit when produced at a mass level.
  • The kit gives results within 20 minutes for symptomatic and asymptomatic patients without using Reverse transcription-polymerase chain reaction (RT-PCR), which is presently considered the gold standard in testing for COVID-19.
  • The low-cost test kit is easy to carry around.
  • IIT-Hyderabad is the second academic institution in the country to come up with a testing kit for novel coronavirus.

3. Air pollution visualizer app by IIT-Tirupati:

  • Using Augmented Reality (AR)IIT-Tirupati has come up with an android based app to visualize and track air pollution in our immediate surroundings.
  • According to the researchers, this app gives a lively and interactive experience using augmented reality.
  • The GPS imagines the air pollutants present in the users’ area based on the data released by the Central Pollution Control Board and also informs them about sources and health hazards.
  • This app visualizes important air pollutants like PM 10, PM 2.5, NO2, SO2, CO, O3, and NH3.
  • This app can be used in 130 stations across the country link with Central Pollution Control Board. The app is available on Google Play Store but works only on AR Core supported devices.
