Geothermal gases result from degassing of magma chambers underground and fluid-rock interactions within a geothermal reservoir, these gases are most commonly carbon dioxide (CO2), hydrogen sulfide (H2), and methane (CH4).
Putaputa ake ai te hauwhatu i te tahenga o ngā hau i ngā wāhi nukutoto i raro i te whenua me ngā taukawekawe o ngā wai me ngā toka i roto i te māpuna hanawhatu. Ko te nuinga o aua hauwhatu ko te hauhā (CO2), ko te hauwai pungatara (H2S), ko te mewaro (CH4).
Hydrogen sulfide (H2S) is the geothermal gas that we smell in Rotorua particularly around Sulfur Point and Kuirau Park coming to the surface with geothermal fluid in hotpools as well as steam.
Rangona ai te hauwai pungatara i Rotorua nei, ā, ka tino rangona taua hauwhatu nei i Motutara me Kuirau e puta ake ana i te waiwhatu o ngā ngāwhā me te korohū hoki.
