ICMS Excursion to Chobhar
On 21st March 2015, first semester students of ICMS went to Chobhar, Kirtipur for a geological excursion. Chobhar was chosen for the field trip specifically due to the complex geological structure of the area, which can teach crisis managers about important geological hazards. They were led by Dr Tara Nidhi Bhattarai, a noted geologist of Nepal who teaches geological processes and natural hazards at ICMS. The field was planned to teach the students the practical aspects of geology and how they relate to crises – both natural and manmade.
Students learned how to use Brunton Compass to locate the geomorphic features on the topographical map. Burton Compass was use to find out the strike direction, dip amount and dip direction of a geological structure. These information are vital to carry out excavation works as they give information regarding the orientation and attitude of the geological structure. They also studied the different types of rocks and geological structures around the Chobhar Gorge. Limestone was the most common rock found in the area which was verified by the students by using hydrochloric acid.

Moreover, the students learned how to identify the potential landslide hazards in the cliffs around Chobhar area. They identified various specific areas which had the potential for toppling, plane and wedge failure.

The main aim of the excursion was to make the students aware of the practical aspects of what they had been learning in their classes. Students were able to learn how to apply their knowledge in a practical manner and to get a firsthand knowledge regarding the various geological structures and their implications for crisis management.
