The one-station detector used for the Arkhangelsk bulletin is based upon a three-component power detector combined with visual identification of corresponding P and S phases. The azimuth is then determined by the P phase through polarization analysis, and the epicentral distance is calculated based ...

We tackle the limited detection capability of global networks in the Antarctic region by implementing different single station approaches, substantially augmenting the number of detected earthquakes during the sequence of volcano-tectonic earthquakes. We apply the Lassie detector (https://gitext.gfz-potsda...
Takehiko Hiwatari for his help in measuring radionuclides with the gamma spectrometer and germanium semiconductor detector. This study was funded partly by the Ministry of the Environment, Government of Japan. Author Contributions T.H., H.Y., S.M. and H.S. planned and designed the present ...
An X’Pert Pro PANalytical diffractometer equipped with an X Celerator detector with a Cu X-ray tube (λ= 1.54 Å) and using a Ni-filtered Cu Kα radiation source was used. The diffraction patterns were recorded under the following conditions: current intensity of 30 mA, voltage ...
