Tomography of the 2011 Iwaki earthquake (M 7.0) and Fukushima nuclear power plant area Solid Earth DOI 10.5194/se-3-43-2012 14 February 2012 High-resolution tomographic images of the crust and upper mantle in and around the area of the 2011 Iwaki earthquake (M 7.0) and the Fukushima nuclear power plant are determined by inverting a large number of high-quality arrival times with both the finite-frequency and ray tomography methods. The similar structures under the Iwaki source area and the Fukushima nuclear power plant suggest that the security of the nuclear power plant site should be strengthened to withstand potential large earthquakes in the future.

Magnetopause displacements: the possible role of dust Annales Geophysicae DOI 10.5194/angeo-29-2219-2011 1 December 2011 Large compressions of the magnetopause are proposed to occasionally result from temporary encounters of the magnetosphere with dust streams in interplanetary space. Such streams may have their origin in cometary dust tails or asteroids which cross the inner heliosphere or in meteoroids in Earth’s vicinity. Read more
