I don't quite understand what this project does, for example, in the case of the earthquake in Turkey.

Does it designate fallen buildings, and unusable roads? If so how does one access this info. I spent about 10 minutes on hotosm and osm trying to find & interpret Turkey related data and did not succeed. Found the Turkey tasks, but couldn't make heads or tails of what those tasks were, how to view the output of people doing those tasks, or how to contribute.

HOT's Tasking Manager is a platform for coordinating the work of mappers. Only authorized organizations can create projects, but anybody can contribute.

In this case, Yer Cizenler (yercizenler.org) is coordinating with representatives of local organizations and consultants from IFRC (The International Federation of Red Cross and Red Crescent Societies) for the collection of road and building datasets.

The goal of this tasks is to complete missing data on the map, for example adding building and roads like in this case. Data is then available on OpenStreetMap for different uses. Some examples are:

* View the map on openstreetmap.org * View the map on OsmAnd or other similar software * Download spatial data using Overpass or HOT's Export Tool (https://export.hotosm.org) * etc, etc

The output of people doing those tasks can be seen querying the changes on the map. There's a tool that is currently unmaintained but you can use it to get some additional stats about the contributions:

If you put a date range like "6 February, 2023 12:00 AM" to "6 February, 2023 11:45 PM" and a Tasking Manager project's id (example: 14218) you'll see something like:

Total Unique Contributors: 507

Features Created:

- building: 48962 - source: 34317 - highway: 7770 - highway_km: 924 - surface: 508 - name: 474

Would the state of those buildings or roads be expected to be there? Or is this simply completing the data so people can more easily refer to it in OSM if they want to?

I think one goal is to at least get the state from before the earthquake, even if many buildings are expected to be gone (and then you can just tag the building as destroyed:building=). But you can coordinate humanitarian efforts much easier if you have a rough idea how many people may* still be somewhere where there have been dwellings. At least in other areas HOTOSM have been active the map data has been validated on the ground as well, but that may depend on who is working on that particular project.
