WOGE #504

I was able to guess the location of Ole's WOGE 503 quickly, thanks to the tropical vegetation and the river that disappeared and reappeared near the center of the image. For this edition I will give another (I think) easy challenge, so the Schott rule is in effect.
As always, be the first post a comment with the location and something about its geologic significance, and you win the privilege of hosting the next Where on Google Earth challenge. For rules, tips, and a list of past locations, see Felix Bossert's blog.


  1. 1°41′S 29°14′E - Goma and Lake Kivu, Democratic Republic of the Congo!

    It wasn't an ocean! My guess was right! The green made me search in Africa and was just find the right orientation ...

    Near Goma, lies mighty Nyiragongo

    1. The active stratovolcano with an elevation of 3470 m in the Virunga Mountains associated with the Albertine Rift - Mount Nyiragongo is the key in this landscape. It's unusually fluid lavas are made of melilite nephelinite, an alkali-rich type of volcanic rock whose unusual chemical composition (extremely low silica content) may be a factor in the unusual fluidity of the mafic lavas there. The 2002 eruption reached the outskirts of Goma, covering the northern end of the runway at Goma International Airport and raised the fears of a limnic eruption (like the one in Nyos) or an increase in the mazuku's activity.

      Or, interconnected, the

  2. Congratulations Luis! I'm glad that someone found this reasonably quickly. I have been hoping to use this location for some time. I was waiting to see if you had anything more to add to you comments, but you have covered all the basic facts. If you zoom in closer and go to the historical imagery on Google Earth you can easily see where the 2002 lava flows destroyed large parts of the city. People started rebuilding on the cooling lava almost immediately.

    We look forward to seeing what you have for us next.
