Preheat an oven to 350°F. Butter and flour a 9-inch springform pan or a 9-inch cake pan with 3-inch sides.
Prepare the crumb topping: Whisk sugars, cinnamon, salt, and butter in medium bowl to combine. Add flour and stir until mixture resembles thick, cohesive dough. Set aside to cool to room temperature, 10 to 15 minutes.
In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt; set aside. In the bowl of an electric mixer fitted with the flat beater, beat together the butter, brown sugar, and granulated sugar on medium-high speed until light and fluffy. Beat in the eggs, one at a time, scraping down the sides of the bowl with a rubber spatula. Add the Greek yogurt and mix. Stir in the flour mixture until just combined. Fold in the blueberries. The batter will be quite thick.
Spread batter in the prepared pan. Top with the crumb topping. Bake until a toothpick inserted into the center of the cake comes out clean, about 60-70 minutes. Transfer the pan to a wire rack and let cool for about 15 minutes. Remove the sides from the pan and slide the cake onto the rack.
