The public probably doesn't know or think about the domino arrangements, but they are there in the same way complex systems in a global economy are interconnected. The public will eventually pay attention when the services start disappearing. Every service you can think of (garbage collection, electricity, credit card transactions, deliveries, ...) now requires internet and financial connections. Those require 24/7 electrical service and comms. Generators are good for about a week for cell towers and hospitals unless resupplied with diesel. Skilled labor maintains all of this. And so on. I don't think of landslides as needing our help, but as something unavoidable when a tipping point (lack of maintenance, spare parts, etc) occurs.
