The situation

Due to heavy rains since 16 March 2018 at 17:00hrs on the mountain, landslides hit the riverbed around Sentani causing flash floods with logs and sedimentary rocks that were channeled to the downstream. Nine villages in Sentani sub-district, Jayapura regency were affected. According to Sutopo Purwo Nugroho, the spoke person from the National Agency for Disaster Countermeasure or Badan Nasional Penganggulangan Bencana (BNPB), during eight hours of rains, the rainfall reached its extreme condition up to 235.1 mm/hour. There is an indication that landslide occurred in Cyclop Mountain which is the upstream area. Cyclop mountain is one of the conservation mountains in Papua.

According to the information provided by BNPB and Meteorology, Climatology and Geophysical Agency that was compiled and circulated via e-mail by UNOCHA; as well as information from PMI, on Sunday, 17 March 2019, the flash flood affected nine sub districts in Jayapura regency, and four sub-districts in Jayapura city. Furthermore, according to the report:
