This issue is not exactly new. The city has known for years that it harbors dozens of these sinkholes. Back in 2009, around 50 buildings in Crystal Cave were deemed to be endangered because they either stood on or near sinkholes. Visible cracks were also found in the area during that time.
It's also worth mentioning here that the 157 sinkholes that the Mines and Geosciences Bureau has in its records are just the known ones. There's a possibility that there are more sinkholes out there, they just haven't been found yet. Without your knowledge, your house may be standing on one. That said, if you ever notice something amiss in the ground where your house stands, have it investigated immediately. There are grounds that may look solid and firm but underneath them may lurk a sinkhole. The grounds over sinkholes can break down during strong quakes and heavy rains.
Here's the list of barangays in Baguio City that the MGB hazard map shows as home to sinkholes.
