I’ve looked a little closer at this swarm. Tensor solutions indicate that the mechanism is extensional rather than transform (like the San Andreas). The main pattern falls along a general sw-ne trend, same as what the tensor solutions indicate.

This seems to represent an extensional event of a spreading zone connecting two right lateral fault zones. USGS will probably provide a more detailed analysis, but that is what it seems to be. If it was a conjugate fault set, there would be left lateral movement in the tensor solutions. These are absent.

Thanks for that! Interesting and overwhelming.
