>> subsiding. >> what we notice is the building was subsiding at the rate of 2 millimeter per year, which is pretty small. but it was noticeable because the rest of the area was pretty stable. >> you say it was noticeable. it's not noticeable to the human eye, 2 millimeters a year, it's noticeable through your instruments? >> exactly, and observation from space. so it's noticeable. other places moved, but in particular area, other building did move. it was a localized area of subsidence. we used the european space agency between 1993 and 1999. what we could report is about movement that happen...

Space and we looked at the movement of the air surface of the building. now, we don't like the term sinking because sinking is something that sink into liquid. we usually use the term subsiding. >> subsiding. okay. >> so, what we notice is that the building was subsiding. at a very -- at a rate of 2 millimeter per year, which is small but it was noticeable because the -- the rest of the area was very stable. >> you say -- you say it was -- you say it was noticeable. it's not noticeable to the human eye. i mean, 2 millimeters a year. it's noticeable, through your instruments? >> exactly. it's -...

Measurement in the 1990s. we did a study just a few years ago and we reported it last year. because we were concerned about the rising-sea level. but the -- we need to look at more data and to see if the rate of subsidence is accelerated or change or stopped because we cannot say. but the thing is that the -- the building moved at a very slow rate. but it, still, moved. and usually, things like that associated with some -- cracks in buildings and structural damage. it's hard to say because we never went over that. we just noticed that and we reported that in our study. >> it's, also, interesti...
