I don't think that comparison works.

There, you had relatively short duration disasters where very soon afterwards, coordinated efforts were dedicated to putting the pieces back together.

Now, most of the press and leadership seems to be thinking only about how to manage the health related consequences of an ongoing crisis. I really don't hear anyone strategizing how to put the pieces back together or how to contain the crisis (note that I did not say contain the disease) so things don't fall apart so completely. There is a profound absence of thought amongst those in decision-making positions, at least insofar as I can see.

Everyone can go right back to work after the event is over in a few minutes.

This more comparable to a nuclear bomb where the area is still radioactive and people cannot go back without PPE.

Edit: and like another reply said, this isn't local, so it's more like multiple nuclear bombs in multiple countries across the globe.

So they don't stop all the time. Those events you gave did not cause 3 billion people to be forced to stay at home. A tsunami or earthquake is isolated to a particular place. It may affect a few million. This is a different order of magnitude
