Subsidence In Yambol City Centre

This picture shows of subsidence in Yambol City Centre and is probably cause by exisiting underground work done on the subway that routes its way under the main road. People are still casually walking the path even though it look like further subsidence could easily take place. No warning signs up at all of this earthmoving incident. A children play area is just beyond this and could be affected later on. Another though was whether this was a mild earthquake that caused it?
