Support Earthquake-Place searches

[ThomasThelen]

Right now, earthquakes have two pieces of geographic information:

1. A point geometry (via hasGeometry)
2. A connection to the country that it took place in (via locatedIn)

At the moment, we don't support searching for earthquakes within any of our place facets (ZIP, FIPS, National Weather Zone, County, etc). I think part of the reason for this is that we never defined how the facets should work when earthquakes are selected.

There's a slight differentiation in the semantics between the earthquake's geometry and other hazards like fires. In the case of earthquakes, the geometry specifies the starting location and there isn't additional information about where it occurred (other than the country). Fires on the other hand have geometries that specify the geographic extent.

I think that we should make the place facets available to this hazard type by using the point geometry to locate earthquakes in a given area.

**Example 1 **

1. User clicks the Earthquake facet
2. User enters 93105 as a zip code
3. User sees all earthquakes that originated from 93105

**Example 2 **

1. User clicks the Earthquake facet
2. User enters 01 FIPS code
3. User doesn't see any earthquakes because none started in that FIPS area-even though some earthquakes may have effected it
