[Geysers] Tue 6/30 ~ 3.3 Earthquake in Yellowstone

[Lucille Reilly]

What's interesting about this is its depth.  If I read the map right at the
link below, it appears that the tremor occurred in the mountain range E of
the park.  Although the depth is probably relative to sea level (yes?), it
is probably much deeper under actual earth.
