[quote=Anonymous][quote=Anonymous][quote=Anonymous]Why not talk about the ones in Italy and Myanmar? I don't recall seeing two 6 plus earthquakes in separate parts of the world on the same day. [/quote] It happens frequently. several times in the last month, based on the USGS catalog. In the past year, there were 148 Magnitude 6+ earthquakes globally. That means, close to every other day. If they are random, in a given year, you would expect 23 days per year to have multiple M>= 6 earthquakes, assuming 100% random distribution. (for matlab people, here is how I came up with that: [quote]for i=1:1000 doy=round(rand(148,1)*365); [n,b]=hist(doy,0:365); nx(i)=sum(n>1); end mean(nx) ans = 22.8470[/quote][/quote] Point taken. And most would be epic entered undersea or unpopulated land. My question was more oriented to significant damage and death. [/quote]
