Halifax Explosion


I just got introduced to a bit of history I hadn't previously known.

All rather dramatic!

It would be nice to find pictures of the fragments.

Such a big explosion is likely to ignite all the soot, so the total energy release over ~ 10s interval was likely ~ 5 kt.
Your feet and hands would surely turn into vapor right next to the explosives, not sure about the whole body.

Apparently a cannon was hurled in the air 3km in one direction and an anchor 2km in the other. Both sizable chunks of metal.
Is that what you meant by fragments?

My jaw dropped when I fathomed the quantity of explosive on board and again when I fathomed the horrific way that people died at quite large distances. That's why I posted. The photos are unreal.

I am surprised that I had not heard of this event before.

Google the following, should use up all your "HOLY SHIT!" for the day.

Oppau disaster

PEPCON explosion

A few other "good" ones are:
Heligoland "Operation Big Bang" (1947) - 6.7 Kilotons
Russian N1-5L rocket incident (1969) - between 1-7 Kilotons
Florakis Naval Base Incident (2011) - between 2-3.2 Kilotons

Not man-made but still significant:
2004 Indian Ocean Earthquake (2004) - 26.3 Megatons
Tunguska Event (1908) - Between 10-30 Megatons
Chicxulub impact (66 MYA) - Estimated 100 Teratons
