<span>Sand dunes can encroach on human habitats. Sand dunes move through a few different means, all of them assisted by wind. One way that dunes can move is through saltation, where sand particles skip along the ground like a rock thrown across a pond might skip across the water's surface. When these skipping particles land, they may knock into other particles and cause them to skip as well. With slightly stronger winds, particles collide in mid-air, causing sheet flows. In a major dust storm, dunes may move tens of meters through such sheet flows. And like snow, sand avalanches, falling down the steep slopes of the dunes that face away from the winds, also moving the dunes forward.

USAR (Urban Search And Rescue) is an organization who is dedicated to the location, extraction from dangerous sites and subsequent stabilization of people who have been in the site of a building collapse.
This organization helped victims during the Oklahoma City bombing of 1995 and also made great efforts during the terrorist attacks of September 11th, 2001. Among these efforts were bringing relatives of the victims of the Oklahoma City bombing to New York City in order to provide grief counseling after the terrorist attacks of 09/11/2011.
This would be matrilineal, where the line of the mother was the relevant line, and not of the father: in order to be a king, one needed to have the royal mother and the father was irrelevant. The dynasty would be traced by the female line in this case (even if the kings were the rulers).
