Document Summary
Last nights earthquake was around 4. 5 on the. This fault had a little bit of move- ment on it, which caused the earthquake. The probable cause is elastic rebound from the last glaciation. At one point there was a few km of ice on top of the crust in the montreal area, and now the crust is trying to bounce back upwards. In a geologi- cal time scales, the last ice age was extremely recent, and the crust is still rebounding. will. The aftershocks from this earthquake will be extremely small. This plume is a verticle column of hot rising material. it is under less pressure, and the hot material melts into a liquid. The plume seems to be stationary for millions of years. The evidence of this is the linear chain of islands formed over hot spots. The plates are moving over a stationary plume, which causes a chain of islands to form.
