SEOUL, Sept 30 (Reuters) - South Korea's industrial production fell by a seasonally adjusted 2.4 percent in August, data showed on Friday, posting the biggest decline in 19 months.
The drop is the sharpest since January 2015 when the index fell 3.5 percent on monthly terms, and is short of a 0.5 percent fall estimated by analysts in a Reuters poll. It rose 2.3 percent from a year earlier.
The August reading follows a revised 1.3 percent increase in July, short of a preliminary 1.4 percent gain reported earlier.
