1. There were a few reasons that caused errors during the lab. At first, each student had different distances when they walked. Secondly, each person took a different amount of time to finish. Lastly, some of the students’ speed was faster, while other students were slower. As a result, it was easy to have a few errors during the lab.
2. The seismometer station can only tell us how strong the earthquake was, but does not show where the waves came from. In addition, since the one seismometer station may not be able to measure the wave speed accurately, more than one station is needed to make sure the data is accurate.
3. In my view, the epicentre location can help determine the magnitude of the earthquake. As a result, scientists can usually identify the epicentre location and determine how strong the earthquake is. It is also a reminder to us about what kind of steps we can take when an earthquake occurs.
4. Before an earthquake occurs, we can use the collected data to identity the magnitude of the earthquake. This can help plan earthquake response programs in order to avoid injuries during the earthquake. Furthermore, it is our responsibility to be prepared and avoid heavy casualties from the earthquake. If people aren’t aware of how devastating the earthquake can be, they will not take it seriously and damage can be extensive.
