3. Seismic Noise Survey at Mt. Tsukuba (February 9)

By Dr. Takumi Hayashida, Senior Research Scientist, IISEE

 

Mt. Tsukuba, located about 10 km north of BRI, is one of Japan's 100 famous mountains.

The mountain is composed of hard rocks and is located away from urban areas with high cultural seismic noise, making it a suitable site for seismic observation.

7. Research Paper by Dr. Hayashida et al. Online in Geophysical Journal International

By Dr. Takumi Hayashida, Senior Research Scientist, IISEE

 

Vs30, the average S-wave velocity in the upper 30 m from the ground surface, is widely used to indicate ground-motion amplification.

One way of the on-site Vs30 estimation is to conduct a microtremor survey.
