While I fully agree that the earthquake that rocked Haiti is bad, why is the rest of the story being ignored?
Did the earthquake stop at an international border?
Well, yes, pretty much. Because of the location of the quake's epicenter southwest of Port-au-Prince, the effects of the quake were felt almost entirely in Haiti.
Furthermore, the main population centers of the DR are on the southeast coast of the island, not in the central region along the Haitian border, as the following map shows:
Perhaps the largest town in the DR nearest to the quake is Jimani, which has been affected largely by the influx of refugees from Haiti, not by the quake itself.
If you look at a map, you will see that the Dominican Republic shares the island with Haiti, yet I have heard no mention of death, damage, or anything else about how the DR fared in the earthquake.
Is it because the DR is more prosperous then Haiti?
The DR is only more prosperous than Haiti in relative terms, since both are pretty poor. But then almost every country on earth is more prosperous than Haiti.
BTW, I found all of this information on the web in about 15 minutes. It was easy. You might want to try that sometime.
