Does anyone know how to use the console to trigger a natural disaster?

I've been hit by the Natural Disaster bug once too many times and I'd really like to find a workable fix. The only theory around seems to be to trigger another disaster in the affected region, cancelling out the previous one.

I found a console command to trigger events listed here: http://www.cheatscodesguides.com/pc-...l-2-total-war/

But I can't work out the syntax. The listing reads:

event <start_year[:end_year]> <category[:type]> [<x,y> <scale>] : creates an event

The region I'm going to use is Tunis:

pos 136,63, region id 103 (Tunis Region)

Can anyone tell me what to type into the console please?
