This paper discusses the need for reviewing and updating the seismic hazard studies in Colombia following the catastrophic effects of the Tohoku earthquake March 11th, 2011 in Japan, knowing that: a) Insufficient seismological instrumentation Colombia; b) Insufficient information on active fault lines; c) Lack of implementation in the area of the tsunami, in spite of having suffered several in the twentieth century, especially the magnitude Mw = 8.8 of January 31, 1906; d) The Colombian earthquake-resistant construction standard is not conservative; e) Results of research show pga values greater than the current standard.
