Activity #4: Graphing temperature and depth data from the rumbleometer
The Rumbleometer recorded both temperature and pressure. The pressure data can be converted to an equivalent depth and so shows if the instrument moved up or down during the eruption. The students are asked to graph some of the rumbleometer data and try to interpret it. On the following two pages, you will find completed temperature and depth graphs. According to the pressure data, the eruption started at 15.4 hours and stopped at 17.5 hours. Therefore, the eruption lasted for only 2.1 hours (very short)! The temperature remained elevated for longer as the new lava flow slowly cooled.
