Fixes #325 - Earthquake hazard visualization bounding box

[navarroc]

A bug was introduced by using the reference envelope, which expects x1, x2, y1, y2 whereas the previous expected x1, y1, width, height. This looks to fix the issue, but please check if this is correct.

Sorry I thought I tested it and worked okay but the pod had an error. Let me check and test one more time.

My previous test was not done in the correct situation. Let me test one more time after fixing the dev instance

As you can see, those outputs are identical. Maybe I did it wrong but do you have any idea?
