The day the dinosaurs died (2019)

features an interstellar comet (those go much faster than regular comets, you know) which has broken into fragments, and they're all slamming into Earth. One of the fragments is bigger than the Chicxulub asteroid, so it's curtains for everybody! Everybody except the special few who've been selected to go to a military bunker near Thule air base in Greenland to ride it out and then rebuild civilization after it's all blown over.

Since all disaster movies have to feature a parent being separated from their child and/or spouse and frantically trying to find them amidst all the chaos, I'm probably not giving anything away when I mention that plot element.

> a fiery plume, reached halfway to the moon

> fires consumed about seventy per cent of the world’s forests

> tsunamis, acid rain

> After the fires died down, Earth plunged into a period of cold, perhaps even a deep freeze

An almost unimaginable scale of destruction. It's mind-blowing that life continued at all. I would love to know more about how life prevailed through this period, how anything made it through this extreme bottleneck.

As a kid the asteroid theory was relatively new, and we envisioned it in the context of a Nuclear winter - which was also en-vogue in a way. To think of it as an event happening in a matter of hours is shocking.

Imagine a spherical carrying medium, through which a circular shockwave races. At the other end, were it will crash into itself, it will create a overpressure spike, which directs force inwards and outwards. This spike would have come out were today the philipines and south east asia reside.

Back then there was mostly ocean. https://dinosaurpictures.org/ancient-earth#66

So why was volcanism so off ?

The continued volcanism did prolong the hellscape making it the extinction event it was.
