Changes in hot spring temperature and hydrogeology of the Alpine Fault hanging wall, New Zealand, induced by distal South Island earthquakes

et al. 2014

Thermal springs in the Southern Alps, New Zealand, originate through penetration of fluids into a thermal anomaly generated by rapid uplift and exhumation on the Alpine Fault. Copland hot spring (43.629S, 169.946E) is one of the most vigorously flowing, hottest of the springs, discharging strongly effervescent CO 2 -rich 56-58°C water at 6 AE 1 l sec À1 . Shaking from the Mw7. ) from intermediate-field distances was independent of variations in spectral frequency, without the need for post-seismic recovery. Observed temperature and fluid chemistry responses are inferred to reflect subtle changes in the fracture permeability of schist mountains adjacent to the spring. Permanent 10 À7 -10 À6 strains recorded by cGPS reflect opening or generation of fractures, allowing greater quantities of relatively cool near-surface groundwater to mix with upwelling hot water. Active deformation, tectonic and topographic stress in the Alpine Fault hanging wall, where orographic rainfall, uplift and erosion are extreme, make the Southern Alps hydrothermal system particularly susceptible to earthquake-induced transient permeability.

“…These changes have been numerous: water level changes, drying up and flooding of (water) wells, and changes in water chemistry (Lee et al 2013;Muço et al 2012;Semmane et al 2012; Ratnapradipa et al 2012;Reddy et al 2011;Waggoner 2011;Benmenni and Benrachedi 2010;Liu et al 2010;Malakootian and Nouiri 2010;Mokhtari 2010;Lei et al 2008;Yaltirak et al 2005;Claesson et al 2004;Lamontagne 2002;Tokunaga 1999;Ogoshi et al 1996;Rojstaczer et al 1995;Whitehead et al 1984/85).

Many studies have examined earthquake's impacts on hydrological changes such as drying up and flooding of (water) wells, fluctuation of groundwater levels, and changes in water quality. This paper aims to present water quality changes in the aftermath of a November 2010 earthquake in Kraljevo. Water quality changes followed hydrological, geological, and geomorphological changes. The water parameter concentrations were measured before the earthquake in 2010 and after that in 2010 and 2011, as well as 2009 and 2012. The data from two hydrological stations were used: Kraljevo Zapadna Morava and Kraljevo Ibar. The Canadian Water Quality Index was applied for the calculation of water quality. This method defines the overall water quality and the specific quality of water used for drinking, aquatic habitats, recreation, irrigation, and livestock. A significant decline in the quality of water used for aquatic habitat and a less significant one in the overall quality and the quality of water used for irrigation was recorded in the hydrological station Zapadna Morava. Increased heavy metal concentrations were detected, which caused water quality impairment. A minor decline in the overall water quality and the quality of water used for aquatic habitats was recorded in the hydrological station Kraljevo Ibar.
