Precursory tilt changes associated with a phreatic eruption of the Hakone volcano and the corresponding source model

open access: yesEarth, Planets and Space, 2018
The 2015 unrest of the Hakone volcano in Japan, which began on April 26, generated earthquake swarms accompanied by long-term deformation. The earthquake swarm activity reached its maximum in mid-May and gradually calmed down; however, it increased again

Palaeoecology and palaeophytogeography of the Rhynie chert plants: further evidence from integrated analysis of in situ and dispersed spores [PDF]

open access: yes, 2018
The remarkably preserved Rhynie chert plants remain pivotal to our understanding of early land plants. The extraordinary anatomical detail they preserve is a consequence of exceptional preservation, by silicification, in the hot-springs environment they ...

Infrasonic wave accompanying a crack opening during the 2015 Hakone eruption

open access: yesEarth, Planets and Space, 2018
To understand the initial process of the phreatic eruption of the Hakone volcano from June 29 to July 01, 2015, we analyzed infrasound data using the cross-correlation between infrasound and vertical ground velocity and compared the results of our ...
