Poorly constrained in this case means that the multiple measured points are not confined to one particular location, and they can't really determine the exact epicenter.

1. To compel by physical, moral, or circumstantial force; oblige: felt constrained to object. See Synonyms at force.
2. To keep within close bounds; confine: a life that had been constrained by habit to the same few activities and friends.
3. To inhibit or restrain; hold back: "Failing to control the growth of international debt will also constrain living standards" (Ronald Brownstein).
4. To produce in a forced or inhibited manner.

Sometimes when depth is poorly constrained by available seismic data, the location program will set the depth at a fixed value.
I thought there are and other parameters involved.
When their measurements are poorly constrained, they are not bound to one location but all over the place, and they can't determine the exact depth.
That is why I asked this question about what a "poorly constrained" earthquake is.
Semantics and reading comprehension are pretty tough too.
Sometimes when depth is poorly constrained by available seismic data, the location program will set the depth at a fixed value. For example, 33 km is often used as a default depth for earthquakes determined to be shallow, but whose depth is not satisfactorily determined by the data, whereas default depths of 5 or 10 km are often used in mid-continental areas and on mid-ocean ridges since earthquakes in these areas are usually shallower than 33 km.
Oh, you mean like 'Um, we don't really know'.
In English it means "We have not got a blooming clue" but yes what the others have said is right - the depth, or whatever measurement cannot be accurately determined from the data to a reasonable degree of accuracy.
