What does seismographic data tell us?

strength,size,distance,and location of an earthquake

Why do geysers of erupting hot water occur in Yellowstone?

What will happen after the Pacific plate moves Hawaii away from the hot spot?

It will stop growing

Where do most earthquakes occur?

Along Transform and convergent Boundaries

Why is it called the Ring of Fire?

Because it is a ring of Volcanoes
