Through lack of knowledge, I am not in a position to pass an opinion on the possibility of a hollow earth though it would certainly make more sense than that of the “accepted” Heliocentric version of the place in which we live. Given the geographical distribution of these occurrences, where earthquakes have taken place in pretty much all the corners of our world, with certain areas experiencing significantly higher frequency of occurrence, the inside would resemble that of a moles habitat, albeit at a much lower depth.
There are those that believe that nothing happens in our world without a reason, whether that reason is for fear, control, power, wealth or a combination of all of the aforementioned. Interesting though when you look to find recommendations or policies implemented after any of these” Disasters” that they usually involve massive investment in infrastructure from both public and private sectors as in the case of mandatory seismic upgrading. Re the “ fires “ which have and continue to occur again, in California, Canada, China, Australia and many areas of our world, again there are those who believe that they are man-made, caused by DEW and accelerants.
As someone once said in response when asked : “Why do these things happen in the world “
“They happen because someone wants them to happen”
