Tree ring growth near the Alpine Fault (2 o 2)

Tree ring growth near the Alpine Fault

This close-up of tree rings illustrates how annual tree growth varies. Analysis of closely packed rings in rimu trees near the Alpine Fault has shown that tree growth was poor in particular years: 1210 CE, 1445, 1580 and 1717. Major earthquakes in those years may have arrested the trees’ development.
