                     An Overview of Recent Volcanic


                     Activity Worldwide











                     In order to provide a general overview of recent   eruptions. Anything  beyond  that  list  cannot  be

                     in this book the following list was compiled from   records  of  eruptions  over  time  and  in  many

                     this  table,  many  containing  volcanoes  with  a   academic texts or other public sources. Given the

                     reflecting  reasonably  reliable  records  of  volcanic   during the Holocene.
