whoa, I turned on all magnitudes and you are not kidding. But it is a round area of seismicity about 20 km across. It is mostly SW of the caldera. If the quakes are located within a couple km of correct, would not be a single dike, unless it a flat one (sill).
If you can find out what is going on, please post it.
