You can put 2 extra elements on your page to show also the underlying objects:
In the existing dataview another dataview with datasource over assocation: EarthquakeInfo_Root
In this new dataview a datagrid (or listview) with datasource over association: JsonObject_EarthquakeInfo
This should show you the mapped response on your page.
An improvement I would suggest is to not map the empty in-between object (EarthquakeInfo), but directly associate the JsonObject with Root (1-* and give them proper names).
