Fig. 1.

Compilation of GPS-corrected interferograms derived from ALOS/PALSAR images. The red star is the epicenter of the 2011 Tohoku earthquake. Active fault traces and volcanoes are indicated by thick black lines and red triangles, respectively. Thin black lines are prefectural boundaries. Precise orbit data are used for all the interferograms. An inset at the bottom right focuses on the crustal deformation due to the northern Ibaraki earthquake (Mj 6.1). White dots indicate earthquakes shallower than 30 km, which occurred from 11 March to 4 April. The beach ball diagram in the inset is from NIED (National Research Institute for Earth Science and Disaster Prevention) Earthquake Mechanism Search (http://www.fnet.bosai.go.jp/event/search.php?LANG=en).
