Question

As reported in the journal “Tectonophysics” in March 2015, the world’s largest known asteroid impact zone is located in 
1. Africa
2. Australia
3. South America
4. North America

Answer 1

Correct Answer - Option 2 : Australia

The correct answer is Australia.

• Asteroid impact zone
  • The impact zone was discovered during drilling as part of geothermal research, in an area near the borders of South Australia.
  • Scientists have discovered a 400 km-wide impact zone from a huge meteorite in central Australia which is the largest asteroid impact zone ever found on Earth.
  • A team led by Andrew Glikson from the Australian National University (ANU) found the impact zone from a huge meteorite that broke in two, moments before it slammed into the Earth in central Australia.
  • The crater from the impact millions of years ago has long disappeared.
  • But researchers found the twin scars of the impacts, the largest impact zone ever found on Earth — hidden deep in the Earth’s crust.

• Tectonophysics
  • The prime focus of Tectonophysics will be high-impact original research and reviews in the fields of kinematics, structure, composition, and dynamics of the solid earth at all scales.
  • Tectonophysics particularly encourages submission of papers based on the integration of a multitude of geophysical, geological, geochemical, geodynamic, and geotectonic methods with a focus on:
  • Kinematics and deformation of the lithosphere based on space geodesy (e.g. GPS, InSAR), neotectonic studies, tectonic geomorphology, and geochronology.
  • Structure, composition, and thermal state of the crust and mantle and their evolution in various time scales based on geophysical and geochemical studies.
  • Structural geology, folding, faulting, fracturing, analysis of stress and strain, and rock mechanics.
