New Zealand -Tongariro
GeoLurking´s plot shows the quakes in the Tongario area NZ. Quote: “This is a plot I did of 3 years of quakes (2009 to 2012) for the Tongariro, Ngauruhoe and Ruapehu area. On the second rotation I opened the depth up to 250 km so you can see the descending slab that feeds the volcanic systems as it melts.” Volcanocafe, July 31, 2012
