Eruption Warning
In this SATIS Revisited resource students investigate how scientists monitor seismic activity and warn of impending volcanoes, the limitations of the scientific data collected, and resulting precision level of warnings.
In June 1991, Mount Pinatubo erupted in the second largest eruption in the world, during the 20th century. The Philippine authorities managed to rescue 60 000 people from around the volcano, thanks to timely warnings. The information that prompted these warnings was provided by several teams of scientists.
There is one activity in this unit, in two parts – a starter discussion in which students are prompted to consider how they might have reacted to the alerts of imminent volcano eruption, followed by the main part of the activity to interpret information recorded by research scientists studying the activity of the volcano.
Students read about the evidence gathered by different scientists, are asked to summarise this information, and then to link each rise in alert level with the scientific evidence that prompted it. They consider the limitations of the scientific information, and of the precision of warnings based upon it.
