DESCRIPTION:Soft elastic interfaces can strongly deform under the influenc
 e of external forces\, and can even exhibit elastic singularities. Here we
  discuss two cases where such singularities occur. First\, we describe sur
 face creases that form under compression (or swelling) of an elastic mediu
 m. Second\, we consider the elastocapillary ridges that form when a soft s
 ubstrate is wetted by a liquid drop. Analytical descriptions are presented
  and compared to experiments. We reveal that\, like for liquid interfaces\
 , the surface tension of the solid is a key factor in shaping the surface\
 , and determines the nature of the singularities. \n\n
