摘要：We conducted geophysical observations on the French Polynesian seafloor in the Pacific Ocean from 2009 to
2010 to determine the mantle structure beneath the Society hotspot, which is a region of underlying volcanic activity responsible for forming the Society Islands. The network for Tomographic Investigation by seafloor ARray
Experiment for the Society hotspot (TIARES, named after the most common flower in Tahiti) is composed of
multi-sensor stations that include broadband ocean-bottom seismometers, ocean-bottom electro-magnetometers,
and differential pressure gauges. The network is designed to obtain seismic and electrical conductivity structures
of the mantle beneath the Society hotspot. In addition to providing data to study the mantle structure, the TIARES
network recorded unprecedented data of pressure and electromagnetic (EM) signals by tsunamis associated with
large earthquakes in the Pacific Ocean, including the 2010 Chilean earthquake (Mw 8.8).
