My note -
There was a quote which was mentioned in an article that I read yesterday, that stated, over 800 aftershocks / earthquakes have occurred in the immediate vicinity of L’Aquila since the April 6, 2009 earthquake (of 5.8 or 6.3) that caused such extensive damage. So, I went to find whether that was accurate or not and although I didn’t find that exactly – I did find out it has been a really, really busy place for earthquakes lately, (or aftershocks, depending on how it is considered.) And, I found some really interesting things like how to make a Google map with markers on it and hopefully, how to post it on my blog.
I also found the site for the European-Mediterranean Seismological Centre.
It was great fun until my impatience with Google earth showing me the map points of those earthquakes got the better of me and crashed my computer. I only zoomed in about four or maybe eight times when it came to a completely frozen state. Oh well, and I’m still looking for the fault lines maps of Italy on that site somewhere – with the surrounding territories.
One thing I noticed, was that when I was placing markers on the Google map – it would’ve been really great to have a 3-Dimensional map to have marked the depths and fault structures dimensionally. I’m sure that’s how the geologists are doing it somewhere (where the money isn’t running thin). That would be the way to do it – have a 3-dimensional map and mark the depths at the same time. But, honestly looking at the lay of the land where the earthquake points are occurring – there are some scary facts that easily become evident. There are visible fracture lines in the landscape – even though the Google maps use two year old satellite images, it is easy to see that some jagged shelf lifted straight up in a few places and in others there are obvious rift lines where it looks like a fault can be seen.
Well, it’s interesting to me, anyway. I learned that it is very time-consuming putting those markers on Google maps and I learned that the specialists who spend their time detailing and analyzing satellite photos are definitely making their money, no matter how much they are making – and I learned that there has been a lot of activity in the immediate vicinity of Italy, which was also interesting. I hope the Google map posts – but it doesn’t have all the markers for all the 800-plus earthquakes that have happened in central Italy since April 1, 2009/ (I just can’t get over that number – it can’t be an everyday thing.)
