since the great disaster.

Nobody ever figured out what caused the runaway chain reaction in the waste dump on Lunar Farside. But it drove the Moon out of orbit.

Here on Earth the quakes and tidal changes had people's attention.

But now that we've recovered, we have to wonder at the fate of the people on Moonbase alpa.


For those who don't get it, September 13th, 1999 is when the Moon was "blasted out of orbit" in Space:1999

Has anyone written any decent fanfic about what happened on Earth beginning with the Disaster?

You know.. doing the maths, I'm not sure if the Moon leaving Earth Orbit would actually create earthquakes and tidal waves.

Firstly, the moon wasn't 'blasted' free... IIRC it was more like a continuous burn, with the waste pits acting like rocket nozzles. There was a scene when the base personnel were all flattened by acceleration, and blacked out for several hours.

The moon is thus accelerating away from the earth, in an orbital transfer manoeuvre, but over about a day or more. So, although the Earth's motion will be slowed fractionally, it won't happen at a fast enough rate that non-liner localised deformation of the crust occurs. [aka, the earth doesn't wobble like a jelly].

What will be a significant problem is the lack of tides.

Obviously, the coastal regions will affected first, with inter-tidal species impacted by loss of habitat. Mangrove swaps will die due to the lack of regular inundation and silting up. Various wading birds will starve or have t seek new food sources as the sands between low & high tide won't be exposed. Some ports will become unusable by shipping due to the lack of high tide.

But eventually the oceans will stagnate and begin to die, as the lack of pelagic turn-over by the tides means the oxygen in the deep ocean column is used up, and isn't replenished. Lack of life in the pelagic deeps, means that upwelling columns of water no longer carry nutrients to the surface, which will starve the food chain. The oceans would eventually turn into scummy de-oxygenated pools of brine, with only simple forms of life managing to survive at the surface.

and without the oceans, land life slowly begins to suffocate due to a lack of photosynthesis and a build up of carbon dioxide.
