Abstract. — In may and September 1976 numerous earthquakes happened in Frioul. In this mountainous and rocky country, their results have been increased by its own geomorphological and geological original features : numerous faults and thrut-planes, non coherent landforms in large masses of dolomitic rocks, high dénivellations and many rugged landforms inherited from glacial and periglacial processes of denudation during the last period of cold climate (Wiirm). So the diversity of the geomorphological effects which are described can be explained. They are numerous, and in a very large scale, periglacial slope processes have been removed, non consolidated forms have fallen down on the slopes and in the valleys, and in a general way, many landforms are now fresch again and a new period of weathering is beginning in some places.

Abstract. — Liechtenstein's ouside location explains chiefly its present survival. Landlocked state but not buffer or shatterbelt state, Liechtenstein depends on input iconography for its raison d'être. Present growing economy depends on subtle neighborhood policies with Switzerland, insertion in E.F.T.A. and tax exemptions. The little alpine principality is a classical example of tax haven. The E.F.T.A.' s political evolution and Switzerland's attitude vis-à-vis Common Market are two influential factors for Liechtenstein's future.

Abstract. — Precipitations fall in high quantities upon the New- Zealand Alps (South Island), from 7 to 9 meters a year, 25 % of which are represented by snow. Notwithstanding mild temperatures, they give rise to many glaciers; but the run-off pattern of their emissaries is dominated by rain. Ice melt contributes about 10 %, snow melt 10 % and rain 80 % of their run-off.
