KW: Ian was just saying that it seems like there are more earthquakes in the world than usual. What do all these earthquakes mean? For me, in addition to my empathy for Haiti and Chile, a desire to help, and some apathy caused by the overwhelming nature of it all, I know I have questions about if the pattern of earthquakes has a reason, and if the pattern of earthquake devastation should cause a certain, pro-active response.
Don’t have all the answers yet. But, I did find a good article in the Wall Street Journal (of all places) which seems to explain the nitty gritty details about what is happening with the plates in the earth to cause these earthquakes. And, the article also notes that some very human causes — like megacities and poverty — actually affect the outcomes, death, and consequent drama of the quakes. I think it is interesting that the last big earthquake near that same fault line in Chile was observed and reported on by Charles Darwin in 1835.
The Darwin connection reminds me how important it is to have enlightened people concerned with science and nature, including folks who write about those topics on various levels. It brings to mind for me the wonderful, scientific roamings and ramblings* of Georgiana, The Duchess of Devonshire, in the 1800’s, and the scientific travels and studies of Isabella Bird in the 1900’s (as brought to my attention by the play Top Girls.)
