Hello Oleg - Thank you for thinking of ways to make volcanoes safer. However, bombing and depressurizing volcanoes isn't feasible. Erik Klemetti has a pretty good blog post about it here: http://bigthink.com/eruptions/why-would-you-ever-bomb-a-volcano Thanks, Cheryl -------- Oleg Karapishchenko wrote: I wrote an article about how you could control volcanic eruptions and save lives. "Volcanoes Under Control" I would be glad if you could take a look. https://ideagenweb.wordpress.com/2017/03/06/volcanoes-under-control/ Have a good day. -- Cheryl Cameron Geologist, Alaska Volcano Observatory Alaska Division of Geological & Geophysical Surveys voice: 907-451-5012 fax: 907-451-5050
