In 1852, the astronomer Nils Haqvin Selander travelled past the Arctic to complete a massively time consuming and difficult project – measuring the shape of the Earth. But why was this so important? And why does measurement matter to science at all? Read the Essay by Miguel Ohnesorge to find out

I meant I won't intervene in debates about who the relevant stakeholders are and how participative a decision process must be to confer democratic legitimacy. I did *intervene* in the broader debate about values & quantification by finding a common premise in those former debates 😀

Yes, of course, I do know Greg and always happy to talk earthquakes. My work (a bit of which is on intensity/hazard, again not landslides per se) has been mostly collaborative with @cristianlarph.bsky.social. The best resource for philosophy of seismology more broadly is @terumiyake.bsky.social.

Miguel Ohnesorge @miguelohn.bsky.social · 15/01/2026

There is some work more broadly on seismic hazard too by Luca Zanetti et. al. (IUSS Pavia) and Li-An Yu (National Taiwan Normal University). Both of them are also contributing to the handbook I mentioned.

Miguel Ohnesorge @miguelohn.bsky.social · 15/01/2026

Thanks Marabel! I saw Melvina Ongaro (Milan Polytechnic) give a nice talk on causal inference in landslide hazard research, and she is writing a piece about rationality and hazard for our forthcoming Philosophy of Geoscience handbook with Elsevier.

Topics
Please see below for a non-exhaustive list of suggested topics; we particularly welcome contributions that make contact with this year's conference theme: Ground Truth and Validity.
While the notion of measurement validity is comparatively familiar, ground truth may need more of an introduction. The concept of ground truth has origins in remote sensing, where it is used to contrast the outcomes of a near or ground level measurement with outcomes of a remotely sensed measurement. From these origins, the concept has now moved to a wider use, particularly in machine learning contexts, where it denotes data assumed to be true, which can then be used to calibrate and validate machine learning data. The time seems ripe for a more careful investigation from a measurement perspective of the concept of ground truth-both in its original understanding and in its more metaphorical use.
