Comparable in energy to a B-53 nuclear bomb, minus the radiation. https://en.wikipedia.org/wiki/B53_nuclear_bomb https://en.wikipedia.org/wiki/B53_nuclear_bomb

So a 14 km blast radius it seems.

  Unless it lands in the ocean in which case tidal waves, and if on land, probably an earthquake/shockwave.

    A comparable ocean impact would be the 2004 Indian Ocean earthquake, which was about 3x more energetic.

      I'd assume quakes transform much more energy into tsunami waves than meteorite hit does.

        That is not correct. Earthquakes' energy doesn't all go to displacing water and hence generating tsunamis. An ocean impact is significantly more efficient at transferring energy into tsunamis. https://www.sciencedirect.com/science/article/abs/pii/B9780444515520000163 https://www.sciencedirect.com/science/article/abs/pii/B97804...

        Interesting, I would assume surface wave dissipation to counteract that compared to seabed origin.

      2004 Indian Earthquake was 9.1-magnitude, so it was about 150 megatons of TNT.
      - ortusdux 2y ago
        The USGS estimated 1.1×10^17 Newton-Meters of energy, which converts over to ~26Mt TNT. https://web.archive.org/web/20100404013939/http://neic.usgs.gov/neis/eq_depot/2004/eq_041226/neic_slav_e.html https://web.archive.org/web/20100404013939/http://neic.usgs....

What I just learned from ChatGPT… Asteroids mostly contain the same naturally radioactive elements we find in Earth's rocks - mainly potassium, uranium, and thorium in very small amounts. When they hit Earth, they don't typically create radiation hazards. Scientists have checked out famous impact sites like Meteor Crater in Arizona and found normal radiation levels. While impacts can briefly create some radioactive isotopes through the collision process, it's really the impact's explosive force that does the real damage, not radiation.
