Folasaga
I le viliina o le ea, afai e faigata tele se fau mo le sao i se fasi toso, e masani lava ona fa'aaogaina le samala DTH.O lenei meafaigaluega na fausia mo le eliina ma le eliina.O le pito o le 'pisinisi' - o le fa'amau fa'amau - o lo'o fa'apipi'i i fa'amau fa'amau,' fa'atasi ai ma alavai ua fausia e fa'ataga ai le alu atu o le ea fa'amalosi.A oomi le samala i le eleele, ona fa'amalosi lea o le samala (pei o se vili auala) e ala i le ea fa'amalosi e fafaga i lalo o paipa vili.Ma, a'o fa'avili le meafaigaluega i totonu o le pu, e fa'agaoioia faamau i luga o le fa'avae atoa o le pu.O le tele o samala e taamilo i le saoasaoa o le 20 i le 30 taamilosaga i le minute, ma ta e mafai ona ta i fua faatatau e oo atu i le 4000 i le minute.O lapisi e masani ona feula (feula) mai le pu i le pito o paipa vili taitasi.O samala a le DTH e sili ona aoga i fau maa malo e pei o limestones poo basalts;fa'amalulu, fa'a'au'au fa'alelei e matele e pupuni ai ala o le ea po'o poloka le piston fa'ase'e.
Ae ui i lea, o samala DTH e matua taugata tele ma o lea e sili ona lauiloa i tagata faʻatau pisinisi.
