The 2011 off the Pacific coast of Tohoku earthquake brought severe damage caused not only by the tsunami but also by the ground motions. The present manuscript summarizes the source mechanism/process and the characteristics of ground motions around eastern Japan during the earthquake. For the last two years after the earthquake, many researchers have devoted their efforts to analyzing and discussing the source and ground motions. New findings from some recent works are also cited. We, furthermore, introduce characteristics of ground motions at some typical damaged sites, where no records of ground motions were obtained during the main shock, using time histories of after shocks.

This was conducted to examine the effects of brown seaweed (wakame) on blood pressure and serum biochemical parameters in hypertensive subjects. Of the 37 elderly out-patients with hypertension who started the study, 36 of them completed it. This study was a randomly assigned, case-controlled one. Nineteen patients received a daily dose of 5g of dried wakame powder packed in 12 capsules. Eighteen gender-matched subjects with age difference±2 years, and starting time of participation within±2 weeks, were selected as the control group. Patients visited the clinic every 4 weeks. The observation period was 8 weeks. In the wakame group, the average amount of wakame ingested was 3.3g. The systolic blood pressure (SBP) in this group dropped 13mmHg below the baseline (p<0.01) after 4 weeks, and 8mmHg (p<0.05) after 8 weeks. The diastolic blood pressure (DBP) decreased by 9mmHg (p<0.01) after 4 weeks and by 8mmHg (p<0.05) after 8 weeks. In the control group, no significant changes were seen in either SBP or DBP. However, the differences in reduction in SBP and DBP were significant between the wakame and control groups. Regarding clinical chemistry data, hypercholesterolemia in the wakame group decreased by 8% after 4 weeks. No other abnormal changes were observed in either group. We conclude that wakame has beneficial effects as a supplemental regimen in the treatment of hypertension.
