I've found shallow risks, and shallow geohazards and risks.

Here is an article in both Spanish and English:

"Estudios de riesgos someros
Se conoce como riesgos someros a la ocurrencia, en las primeras capas del subsuelo, de una o varias de las siguientes características geológicas: bolsas de gas, hidratos, fallas cercanas a la superficie, flujos de aguas someras, sedimentos no consolidados, anomalías del fondo marino."

"Shallow risks studies
It is considered as a shallow risk the occurrence, in the first subsoil layers, of one or many of the following geological characteristics: gas pockets, hydrates, faults close to the surface, flows of shallow waters, non consolidated sediments, anomalies of the marine bottom. "

"Shallow geohazards and risks
This team investigates the shallow geohazards that affect the UK and how we can best reduce the risks to society.
We examine and monitor shallow geohazards at local, regional and national scale using a combination of field survey and remote sensing techniques and are available to respond to national emergencies."
