An article in the Malaysian Star<\/a> has various statements confirming that it was a retaining wall failure:-<\/p>\n

National Disaster Mitigation Agency (BNPB) spokesperson Sutopo Purwo Nugroho said the sinkhole was caused by a construction error.<\/em><\/p>\n

\u201cThe retaining wall was not able to withstand the load, especially during the rainy season,\u201d he said in a statement, adding that there was no connection between this incident and two active earthquake faults in Surabaya and Waru.<\/em><\/p>\n

Surabaya Deputy Mayor Wisnu Sakti Buana said the sinkhole was allegedly related to the construction of a parking basement at Siloam Hospital.<\/em><\/p>\n

“This is related to the project on the side of the road. The Siloam Hospital project. They were supposed to build a foundation first, but they didn\u2019t,\u201d Wisnu said as quoted in an interview with KompasTV.<\/em><\/p>\n

Surabaya Development Planning Agency head Eri Cahyadi concurred, saying the incident was purely caused by an error in the project.<\/em><\/p>\n
