"From the previous 3,617 displaced residents, we found more refugees, 150 from Harjobinangun and 162 from Nambangan Villages," said Head of Data and Information Center of BNPB Sutopo Purwo Nugroho, in a written statement on Sunday.
The local administration has issued an emergency in response to the floods and landslides in Purworejo, effective until January 3.
The number of displaced residents is expected to decrease as the water has begun to recede in places such as Butuh, Kemiri, Purwodadi, Bagelen, Bayan, Ngombol, Kutoarjo, Bruno, Pituruh, Purworejo, Grabag, Gebang, and Kaligesing sudistricts, noted Nugroho.
Earlier on Friday (Dec.20), flood and landslides had struck 53 villages in 11 sub districts of Purworejo.
The overflowing Bogowonto River and its tributaries also inundated the villages in the region.
Four residents were reported dead due to the disaster.
The road access to Butuh subdistrict, at the border of Purworejo-Kebumen, which had been cut off, has however been restored now.
"We urge the residents to stay alert on the flood and landslide threat as the peak of rainy season is predicted to occur around January-February 2014," stated Nugroho.(*)
