It's a very unusual area for such large activity. So in those terms it is exciting that it occurred there. The department wants more information however. To find out what happened and why, a field team of seismologists and technologists were sent to Northern Alberta, on April 16. They will spend a couple of weeks setting up seismometres and gathering information.
Aftershocks are primary sources of information.
Since April 13, five have been reported. That is nothing out of the ordinary. During bigger earthquakes, they can continue for months or weeks. During smaller activities, they tend to peter off within a few days or a week. But everything will be measured, recorded and brought back to the department.
