AbstractOn October 9, 2007, an unusual sequence of earthquakes began near the community of Nazko, British Columbia. Within 24 hours, eight earthquakes of magnitude 2-3 occurred in a region where no earthquakes had previously been recorded in more than 40 years of monitoring. This cluster of earthquakes was located near the Nazko Cone in the Anahim Volcanic Belt of central British Columbia and immediately raised concerns that this could be the precursor to a volcanic eruption. There was a high-level of concern in local communities, and a very high-level of interest from the media (several of whom did "live from Nazko Cone" news broadcasts).
Questions that were raised included: "What do these earthquakes mean?"; "Will there be a volcanic eruption?"; "What would be the impact in local communities?"; "When might a volcanic eruption occur?", and "What would be the warning signs?".
Within a few days a Technical Advisory Group was formed to address these and other questions. The group was comprised of seismologists, geologists, volcanologists, and emergency managers from academia, federal and provincial governments. In this presentation we summarise: 1) the important role of "real-time science" - that is obtaining the necessary data and interpreting those data for decision-making; and 2) the critical interactions between scientists and emergency managers.
