Note: it is difficult to stop the following graphs from updating so that they may not show the phenomena that I saw.  I have attached some images that may be more relevant


Adak, Aleutian Islands, Alaska)






Pohakuloa, Hawaii, USA)




Yuzhno Sakhalinsk, Russia)




Idaho Springs, Colorado, USA)

How many of the above are natural events?
