13. Answers: Natural Hazards Round 2
Convection
Divergent / constructive plate movement
Iceland
Tectonic plate movement of all types (collision, divergence, convergence, transform/conservative)
Richter (measures scale of seismic shocks) / Mercalli (measures impacts)
Retrofitting, rubber foundations, ball-bearing joints, shatterproof glass, counter-weight, etc.
Above 27°C
Gas measurement, seismometers, soil or water acidity, etc.
Saffir Simpson Scale 1-5
True. E.g. if climate change/global warming leads to ice melt then the loss of the weight of ice above a magma chamber can cause pressure changes, etc.
