Abstract. Background: Monitoring of suicide rates in the recovery phase following a devastating disaster has been limited. Aim: We report on a 7-year follow-up of the suicide rates in the area affected by the Great East Japan Earthquake, which occurred in March 2011. Method: This descriptive study covered the period from March 2009 to February 2018. Period analysis was used to divide the 108-month study period into nine segments, in which suicide rates were compared with national averages using Poisson distribution. Results: Male suicide rates in the affected area from March 2013 to February 2014 increased to a level higher than the national average. After subsequently dropping, the male rates from March 2016 to February 2018 re-increased and showed a greater difference compared with the national averages. The difference became significant in the period from March 2017 to February 2018 ( p = .047). Limitations: Specific reasons for increasing the rates in the recovery phase were not determined. Conclusion: The termination of the provision of free temporary housing might be influential in this context. Provision of temporary housing was terminated from 2016, which increased economic hardship among needy evacuees. Furthermore, disruption of the social connectedness in the temporary housing may have had an influence. Our findings suggest the necessity of suicide rate monitoring even in the recovery phase.

Measurement Line

Numerical modeling of the problem of dam monitoring by the Electrical Resistivity Tomography method is carried out. The mathematical model is based on integral equations with a partial Fourier transform with respect to one spatial variable. It is assumed that the measurement line is located across the dam longitude. To approximate the shape of the dam surface, the Radial Basic Functions method is applied. The influence of locations of the water-dam, dam-basement, basement-leakage boundaries with respect to the sounding installation, which is partially placed under the headwater, is studied. Numerical modeling is carried out for the following varied parameters: 1) water level at the headwater; 2) the height of the leak; 3) the depth of the leak; 4) position of the supply electrode; 5) water level and leaks positions are changing simultaneously. Modeling results are presented in the form of apparent resistivity curves, as it is customary in geophysical practice.
