P1 practices: knowledge gaps Flashcards
how can volcanic hazard be reduced using GPS crater monitoring?
GPS = satellite imargery = monitoring of ground surface
abnormality / deformation of ground (Eg magma chamber swelling)
= early warning and evac
how can volcanic hazard be reduced using lava diversions?
barriers, water
divert from populated areas, roads and infrastructure
reduced damage, essential services still functioning
outline one factor affecting the speed of a mass movement
slope gradient
soil moisture content
suggest two pre-event management strategies that could reduce the negative impcat of mass movement in mountainous areas with high rainfall
slope stabilising – vegetation, bolting, retaining walls, terracing
land use planning
outline one reason high mag earthquakes dont occur very often
high magnitude corresponds with an extremely large release of built up tectonic stress
thru plate interactions (friction)
to build up enough stress for a high mag eq would take far longer
how does the age structure of a population affect the risk to a community from an earthquake?
older = decr mobility, reaction time, health
= slower evac = death
younger demographic = able-bodied and healthy = can help others, evac quickly = saves lives
outline one reason why people may underestimate the risk of a geophysical hazard occuring in their local area
lack of hazard education and awareness –> risks, protocol
explain 2 management strategies to increase site resilience in rural tourist hotspot areas
sustainable touristic practices – limiting carry capacity
community involvement
- benefits locals
- stewardship of local resources
explain why participation in sports might increase over time for women
media representation
awareness of opportunities (civil society ish)
explin why participation in sports might increase over time for low income groups
incr accessibility and facilities
awareness of health benefits
