B2 - EFFECTS OF VOLCANISM AND EARTHQUAKES
What hazards are associated with volcanism?
There are many different primary and secondary hazards associated with volcanism including: volcanic bombs, lava flows, nuee ardentes, lahars and pyroclastic flows.
This is a detailed introduction to volcanic hazards

This is brilliant - once you have read about nuee ardentes, try this experiment. The video is in French, but you'll get the idea!

This lahar in Japan is pretty terrifying, it shows the raw power of this volcanic hazard
This video demonstrates how pyroclastic flows work using a dry ice experiment
effects of volcanism
There are many social, economic and environmental effects of volcanism including: destruction of property, loss of life, climate change, enhancement of soil fertility, creation of landmasses and geothermal energy
This video shows how the USGS monitors and address the effects of volcanism

These are some of the positive effects of volcanism and reasons why people choose to live near active volcanoes despite the associated hazards. Watch the video and list the positive effects.
Volcanic activity can have far reaching impacts and many of them negatively affect people, the economy and the environment. This video lists the basic negative imapcts
Now you have the basic concepts watch the following video about the effects of volcanoes in Iceland, make relevant case study notes
hazards associated with earthquakes
There are also a variety of hazards associated with earthquakes including: tsunamis, liquefaction and mass wasting
This is a good basic introduction to each associated hazard with accompanying videos

This is an interesting documentary about earthquakes if you have time!
