Why might the infiltration of water deep into a slide mass increase landslide hazards?

Inflitration of water deep into a slide mass increases landslide hazars.

Explanation:

Infiltration causes landslide that create hazards in people through property damage, remediation costs.

Lans slides are common in hilly and mountain region.

The large size of water shed allows significant amount of infiltration by melting the snow into the hill slope region.

The hydrological properties that are present in soil causes change in steepness of the dip bedrock located below the land slide.

These factors control the direction, speed, and the amount of ground water that travels through the slope.
