Well, rocks that have been held by ice become loosened by melting snow, and they slide downhill.
The above answer is true, but in a more general form; a rockslide occurs when abrupt movements of masses of geologic materials, such as rocks and boulders (there is a difference), become detached from steep slopes or cliffs. This "separation" occurs along discontinuities such as fractures, joints, and bedding planes. The movement then occurs by free-fall, bouncing, and rolling. Rockslides are strongly influenced by gravity, mechanical weathering, and the presence of interstitial water.

What is an indication that rockslides have occurred there?
There are typically many large rocks prominently obvious with little soil cover. There are 3-4 large landslide sites near me and they are very obvious.
What causes the earth's movement in an earthquake?
The kinetic energy of moving rock masses underground is transferred by vibrations to the surface, where it causes shaking or harmonic motion. In some earthquakes, the movement of rocks can cause large areas to change in height, either elevated or dropped by several feet. In others, there can be a significant lateral shift, ripping structures apart. One other notable effect is liquefaction of soils, which can cause rockslides, or collapse structures as the supporting layers beneath the surface give way.
