The analysis in this Twitter thread correlates the observed degree of damage with the distance from the explosion. It comes up with an estimated 240 tons TNT-equivalent, though naturally this comes with a considerable margin of error.
...
This Twitter thread is making the point that the explosiveness of ammonium nitrate can vary significantly depending on how it is stored. 2750 tons of AN at 20% efficiency gives 550 tons TNT.
...
This range is also apparently consistent with the explosion registering as a 3.5 seismic magnitude.
...
There are still a great many unknowns, and none of this should be mistaken for the real analysis which will come later, but these disparate sources of information all seem to agree with each other, to a first approximation.. -
Some insane footage out there
Number 5 or 6 I think it is is brutal.

The white swirling cloud was the shock wave condensing moisture in the air

'stored since 2014' - one person a day could take home a kilogram and a bit, sprinkle it on their garden and the problem would have gone...

@antipodean really? i thought someone said it was only last year, storing something so obviously dangerous for that long...wow

The article I posted says apparently the authorities were told it was dangerous but did nothing. Oops

pretty sure an article I read indicated port authorities had been warning of the risk for many years??

Those poor people. There will be many lives lost; lots of injured people; homes destroyed. Not to mention the long-term impact on people's physical and mental health.
I hope the people of Beirut get all the help they need.
What an bloody awful year this is. What's next? Locusts? Frogs? Three days of darkness? If I believed anything written in the Bible, I'd be thinking the apocalypse is coming.

Worth remembering that bad things have always happened, we just hear about them all now. Also, by every measure this is the best time to be alive.
It helps me to keep perspective when these awful events hit closer to home.
These videos are just incredible. You can see people on the streets and in cars that just have to have been killed. Nothing they could have done.

Quite a lot of reports on radio on way to work - Doctors who rushed in to work only to find their hospital gone etc.
Everyone involved in port management for the last six years under house arrest. I guess that's if they have a house. Estimated 200K homeless - at least temporarily

Incredible!
I wonder if there is anyone in Beirut that is around 70/80 that has lived there their whole life. Imagine what was going through their head when they heard/saw the explosion.
Terrifying
