This is a genuinely astonishing interpretation of statistics.
The reason the average number of deaths in Europe is low is because it's rare. Two of the 25 biggest 20th century earthquakes by fatality (globally) were in Italy, and it's a whole other debate as to whether the Izmit 1999 earthquake was in Europe or not, but for your argument let's say it was. That's just three out of 25, if anyone can find a longer list than this then please share and we'll see if that is the trend or not. I would imagine it is as Europe is mostly safely inside the Eurasian Plate.

The majority of European earthquake deaths (132,000 out of 202,000) happened in 1908, 1915, and 1999. It makes absolutely no sense at all to make this a weekly average, as if it were like road deaths.
There were 71 total eclipses globally in the 20th century. I'm not intending to look through every one of them, so I just checked the years. In 1908, one went over the Pacific from the Marshall Islands to Costa Rica (not near Europe); in 1915, one went from Australia to Japan (not near Europe); and a second in 1915 was also over the Pacific and only visible from Japan. And of course in 1999, one went from a little bit of Cornwall, over Turkey, and on its way to Pakistan.

So that's one example I can find, and that's not even the X that you talk about in the opening post. If there was a correlation, there would be more examples. And let's be honest, a scientist would have spotted it by now as earthquake prediction is notoriously inexact.
