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. Answers: Natural Hazards Round 2
