Konstantinos Michailos from the Australian National University and co-authors have found that clusters of earthquakes occur near to the Fox Glacier/Te Moeka o Tuawe, Franz Josef Glacier/Ka Roimata o Hine Hukatere, Tasman Glacier/Haupapa and Murchison Glacier/Te Hiwai. What is more, the shallow earthquakes at these locations have seasonal cycles, generally peaking in winter, summer, or both. Digging even deeper, they found that for the Murchison Glacier/Te Hiwai earthquake cluster there was a correlation with high rainfall events. The hypothesis they present for this rainfall-seismicity relationship is that when general strain rates within the basement rocks are high, increased groundwater pore-water pressure caused by large rainfall events can be enough to trigger earthquakes. This is a convincing story, but they also point out that the spatial differences in rock types, groundwater depths, strain rates, glacier dynamics, snow-induced land deformation and monitoring equipment means that the rainfall-earthquake relationship is not clear-cut everywhere. So for the Murchison Glacier/Te Hiwai area it may be reasonable to tack earthquake occurrence onto the end of the weather forecasts. Elsewhere there is still some work to be done before “weather” based earthquake forecasts might be applied.
