The 2001 Taupō Fault Belt Seismicity as Evidence of Magma‐Tectonic Interaction at Taupō Volcano

Abstract The Taupō Volcanic Zone (TVZ) is the southern extent of Tonga‐Kermadec volcanic arc and encompasses Rift, with two structures accommodating extension through central North Island New Zealand via magmatic tectonic processes, respectively. Interplay between components TVZ Rift are evident at volcano, which exhibits periods increased seismicity on a decadal scale. One period occurred in 2001 outside caldera adjacent Fault Belt. We use seismological analysis to detect characterize Belt seismicity, aligns clusters close active faults, was preceded by large cluster earthquakes beneath Lake Taupō's Western Bay. This temporal change local stress field imply that intrusion Bay initiated unrest fault belt. Our suggests this may have silicic reservoir it represents an example interaction regional deep mafic systems Taupō.
