Understanding phreatic eruptions - recent observations of Kusatsu-Shirane volcano and equivalents -

Earth, Planets and Space welcomes submissions to the special issue on 'Understanding phreatic eruptions - recent observations of Kusatsu-Shirane volcano and equivalents -'.

It has been two years since the unexpected eruption of Kusatsu-Shirane volcano (Moto-Shirane) on January 23, 2018. The eruption took place after the 1,500 years of dormancy. It shed light on the difficulty on the prediction of phreatic eruptions but also motivated studies on the long-term and more regional scale studies of the dormant volcanoes. This special issue will include the past and on-going researches on the Kusatsu-Shirane volcano with varieties of disciplines such as seismology, geodesy, geomagnetism, geochemistry, petrology, and risk assessment of volcanoes. We also  welcome papers on the similar volcanoes with phreatic eruptions.

Submission Instructions

Before submitting your manuscript, please ensure you have carefully read the submission Guidelines  Earth, Planets and Space. The complete manuscript should be submitted through the Earth, Planets and Space submission system. To ensure that you submit to the correct special issue please select the appropriate special issue in the drop-down menu upon submission. In addition, indicate within your cover letter that you wish your manuscript to be considered as part of the special issue on 'Understanding phreatic eruptions - recent observations of Kusatsu-Shirane volcano and equivalents -'.
All submissions will undergo rigorous peer review and accepted articles will be published within the journal as a collection.
