The geology of Fiji and its evolution as a volcanic island arc chain are very complex. Originally in-line (Vityaz Arc) and connected with the Vanuatu volcanic island arc chain, there was a complex polarity reversal and separation event (Ontong Java Plateau collision with Solomon Islands and subduction of Samoan seamounts […]
The development of Mineralisation and Geothermal Resources around the Ring of Fire is also impacted by the seismic risks here. The nature of tectonic convergence and subduction zones means that earthquakes are normal events. Open Pit mines have been successfully designed and constructed to withstand strong earthquakes, but there have […]
A normal requirement for many open pit mines is dewatering to remove water inflow as the mine depth extends downward below the water table. Various wells would be located around the open pit perimeter to remove water and to preclude inflows from adjacent areas. Pressure and thermal monitoring boreholes would […]
