Studied by 12 people
where are volcanoes found (2)
plate margins, hotspots
where are lots of volcanoes concentrated
pacific ring of fire
where do narrow belts of earthquakes form
constructive and conservative plate boundaries
where do wide belts of earthquakes form
destructive plate boundaries
what can form as a result of volcanic eruptions (2)
islands, continents
where do the most fatal landslides tend to form (2)
tectonically active regions, areas with high precipitation
what is the general trend between frequency and magnitude
as frequency increases, magnitude decreases
how does the richter scale work
an increase of 1 means an earthquake that is 100x stronger
the richter scale is being replaced by the moment magnitude scale. what is this
an increase of 0.2 represents a doubling of the energy released by the earthquake
what does the volcanic explosivity index measure
the amount of material ejected, the height of the eruption, the damage caused
what is a level 5 VEI eruption considered
very large and violent
