What are the red lines look below
Therefore based on your previous answer what plate do most earthquakes occurred on
4. Look at the earthquake risk maps below is there an area in the middle of the country where the earthquake risk is high and where is it?

What is the name of one these volcanoes4. Find Mount Rainer or go to https://volcanoes.usgs.gov/volcanoes/mount_rainier/and click on the tab called hazards
Look at the map and what is the major hazard for communities around Tacoma Washington.
Why does this underline the dangers of volcanoes beyond eruptions?
