The Instituto Nacional De Prevencion Sismica listed some 57 Argentine (mag =>5.0) earthquakes that occurred between 1780 and 1995. Of this figure, 32 occurred in the 12 months beginning January 20 of those 9/56 years in Table B this appendix (significant: p < 10-4). 

A notable seasonal trend in the timing of these events could not be established.
