Something creepy is happening
In this activity, students explore tectonic movements called slow slips. They plot and interpret a graph using data from an actual event in New Zealand.
Slow slip events can be tricky for students to understand as they involve very small movements, but they are a great extension study for students who have an understanding of the more well known form of earthquakes.

Activity ideas
Satellites and receiving stations play a key role in providing data about slow slips. Learn more about Earth movements, then build a satellite to monitor them and use this activity to interpret the data you receive.

In 2011, scientists from around the world met in Gisborne to consider how to study slow slips.
