Origin of the filamentary structure in space plasmas

We propose a scenario that filamentary structure appears together with propagating waves on the scale of ion gyroradius. The method is based on two-dimensional ion particle-in-cell (or hybrid) simulation in lo...

A traveling atmospheric disturbance generated by a soil colour change in a high-resolution climate model experiment

The climate model CESM-WACCM is used to study the way a soil colour change of the eastern region of the Sahara affects the dynamics of the troposphere. The soil colour is darkened for 5 days. The difference be...

A post-Tohoku earthquake review of earthquake probabilities in the Southern Kanto District, Japan

The 2011 Mw 9.0 Tohoku earthquake generated an aftershock sequence that affected a large part of northern Honshu, and has given rise to widely divergent forecasts of changes in earthquake occurrence probabilit...

Remarkable ground uplift and reverse fault ruptures for the 2013 Bohol earthquake (Mw 7.1), Philippines, revealed by SAR pixel offset analysis

By applying a pixel offset analysis using RADARSAT-2 SAR data to an inland crustal earthquake that occurred on Bohol Island, Philippines on 15 October 2013, we succeeded in mapping a ground displacement associ...

Geohazards and myths: ancient memories of rapid coastal change in the Asia-Pacific region and their value to future adaptation

Rapid coastal change is common in the Asia-Pacific region yet an understanding of its causes, recurrence times, and impacts is not always clear through the use of conventional geological methods. It is suggest...
