steep slope profile. and more of a conical shape. and i want to show you where goma is located. it's this population density right on the lake shore of lake kuvi. that is, again, an area that is away from the actual volcano. and according to authorities, the lava is flowing, again, away from the populated density areas. but that's good news because this area is a highly populated area. you can see rwanda, burundi, and the eastern sections of congo with that dark shade of red and orange. we're talking about over a half a million people according to the latest estimate in goma. and of course they're fearful because they don't want to see a replication of what happened back in january of 2002. we do have the potential for acid rain with this particular volcanic eruption. you get the mixture of sulfur dioxide with moisture in the atmosphere and that leads to a by-product of acid rain. so that's also something we will monitor closely. michael? >> yeah. i've been to goma.
