In part 2 of our 4 part series on earthquake prediction, Dr. Jones explains the idea of how the rate of earthquakes  can be  the piece of information that helps know if another earthquake is more likely.  She explains why people think she can predict earthquakes, when really, she's just explaining the science of what makes an earthquake more likely (hint: earthquakes never happen by themselves!). She helps explain why the San Andreas Fault is different and can be seen as more likely than other earthquakes and when a one day rate might go up around it, where people might think a prediction is being made when triggering is involved. We also reveal the things you should listen for when scientists talk about what's potentially going to happen next.
