Opportunities in agriculture, business and employment attracted more settlers into the area, particularly during the year 1957 and 1958. The influx of settlers was given more impetus when the Samar Mining Company (SAMICO) constructed the existing SAMICO road from Bobuan to its wharf in Pamintayan. By 1959, Bayog was already quite big for a barrio. So another barrio was created which is now the present barangay Kahayagan. When the municipality of Buug (also a former barrio of Malangas) was created in 1960, barangay Bayog and Kahayagan were among the barrios under it.
