Abstract	Registros instrumentales extensos de precipitacion son de amplia utilidad ya que permiten evaluar el comportamiento de eventos extremos como las sequias a multiples escalas temporales. La ciudad de Santiago de Chile posee un registro historico desde el ano 1867, siendo uno de los mas antiguos y completos de America del Sur. En este estudio se analizo la ocurrencia de sequias definidas por umbrales de precipitacion (moderadas, severas y extremas), considerando los meses de abril - octubre entre los anos 1867 - 2015. Los resultados muestran un incremento en la ocurrencia de toda clase de sequias desde 1930, y un incremento de sequias consecutivas de 2 a 4 anos sin precedentes dentro del periodo instrumental. En adicion, un incremento de sequias extremas ha sido registrada desde el ano 1950 en los meses de mayo a julio, revelando condiciones invernales mas secas para la ciudad de Santiago.
