Time = 16:39:43 UTC
Depth = 57.5km (35.7mi)
Type of plate boundary = oceanic-continental
Earthquake is located on the oceanic-continental plate boundary because it located
between the Australia plate and the Pacific plate.

Discussion:
1. Interpreting our world from an aerial viewpoint has been very interesting
and educational allowing any place in the world to be brought to our homes
to view. However, there are ethical and civil issues that come into play with
this type of access being so readily available. Privacy could be considered in
violation as anyone can type in a home address in Google Earth and “see”
where someone lives and what their surroundings look like. This could cause
potential problems with people feeling like they are being spied on even
though the images are static. There also isn’t a way to opt out of having your
home on display creating more concern for violation of peoples’ rights.
2. Before starting this assignment I didn’t really think about earthquakes in
Utah. Now I have a much greater understanding for why our surroundings on
the Wasatch Front are as they are. The constant movement along the
Wasatch Fault has given us the spectacular mountains we are so lucky to love
by. On the other hand we are in the path for an earthquake that is more
difficult to understand since we do not live on a plate boundary, but mid-
plate in the Intermountain Seismic Belt. Also, living relatively close to
Yellowstone where a hotspot volcano is found puts us in a more actively
dynamic environment. We need to make sure we are prepared for when a
major earthquake might happen here with emergency plans and procedures
at home and in our work place and what our immediate actions might be.
Otherwise we need to live and enjoy this beautiful space we live in but be
mindful to the every moving ground.
