Any change in seismic activity increases our vigilance should the change develop into something threatening. This ongoing earthquake swarm southwest of Bend, Oregon, is just the sort of thing to trigger such vigilance. Because of the proximity of young volcanic vents in the area the Cascade Volcano Observatory is also taking an interest and as of today is installing an additional seismic station near the swarm.
A large earthquake in this area is always a possibility or even a volcanic eruption. However, at this time both of these cases are considered very low probability events.
