We compared the number of M > 2 earthquakes in an area, including the island of Crete, Greece, to the number of admissions to the Psychiatric Inpatient Unit of the University of Crete (IPU/UoC), during the period 2008-2010. We found that when earthquakes with M >= 6.4 occurred in the region examined, the number of monthly admissions to the Acute Care Unit of the IPU/UoC, N-AA, reached lowest values, whereas this number increased when the monthly number N-E of small (M < 3) earthquakes increased. We also found a positive correlation between the total number of monthly admissions N-A and N-E (r = 0.601/P = 0.001). When a daily resolution analysis was performed for the month with the highest value of N-E, we found that an abrupt increase in the number of small earthquakes was followed by an increase in the number of admissions after similar to 2days (during that month, from a total of 71 patients, 38/10 people were diagnosed with schizophrenia/bipolar disorder). We hypothesize that seismic activity might be a significant contributing factor influencing the frequency of admissions of psychotic disorders in Crete in the period 2008-2010 and that the beneficial/adverse effects are related to the anomalous electric field/extra low frequency-ultra low frequency emissions.
