- Summary
- In 2017, with the beginning of phase II of the project, we carried out various geophysical studies focusing
on the Terror Rift, where tectonic earthquake events are highly active. Employing teleseismic
data from Jang Bogo Station, we computed a three-dimensional P-wave seismic velocity model beneath
the Terror Rift and Jang Bogo Station and found two low velocity anomalies beneath the Terror Rift
and Mt. Melbourne area. As a result, we discovered a low velocity layer to be evident in the lower
parts of the Terror Rift and confirmed that the rift activity oriented in the East-West direction was caused
by hot mantle material from its buoyancy moving into the cold lithosphere and spreading in the East-
West direction,
To compute a model with higher resolution and measure tectonic activities at the Terror Rift, 5 ocean
bottom seismographs will be deployed during the 2017-18 summer Antarctic field season, and yearround
data will be retrieved during the 2018-19 summer Antarctic field season.
