Di Dongengan ini ada link ke paper tersebut http://rovicky.wordpress.com/2010/11/10/hubungan-gempa-dengan-erupsi-emang-ada-tapi-apa-artinya/ Dongeng satu lagi tentang relasi temporal gempa-vulkanik yang tidak sederhana ada disini : http://rovicky.wordpress.com/2010/11/13/hubungan-vulkanisme-dan-gempa-1-temporal-relation/
