What observations can you make from the graphs of the rumbleometer data?

What can you conclude about what happened to the instrument during the eruption?

Why did it survive and not get completely buried in lava?

When did the eruption start and how long did it last?

How much did the water temperature increase?

The lava erupted at a temperature of 1200° Celsius (~2200° Fahrenheit). Why do you think the temperature recorded by the rumbleometer didn't rise more?
