"Through field measurements we can classify three types of flow in terms of insulation and efficiency of heat loss: (1) heavily crusted, (2) tube-contained, and (3) poorly
crusted.
...
(1) Heavily Crusted. ....
The presence of a stable, thick and cool (30-150 °C,
typically 40 °C) surface crust, however, reduces surface heat loss and core cooling to just 0.5-1.1 x 10^3 W/m2...

(2) Tube-contained. ...
For lava tubes on Kilauea (Hawaii) fed at effusion rates of 1-4 m3/s, these result in a total heat loss of 5 x 10^4 W/m....

(3) Poorly crusted. ...
We completed a 2-day-long thermal survey of a proximal
section of active lava channel at Etna (Italy) using a FLIR thermal camera during May 2001. The channel was fed by a DRE effusion rate of 0.1-0.7 m3/s and pixel-integrated
surface temperatures varied between 220 and 980 °C, with a mean of 680 °C. Heat losses were dominated by radiation (5 x 10^4 W/m2) and convection (10^4 W/m2)...

As far as my question about areas of earth having around 200 w/m2, I didn't find anything specifically. But perhaps Iceland or large areas of it would be somewhere around this:

"Iceland is the youngest landmass on Earth, and the second largest island in Europe, exceeded only by Great Britain.... Iceland's total surface area is one hundred and three thousand square kilometers. Roughly one ninth is inhabited. The remainder is covered with mountains of ice and desolate plains of lava and ash. The highest point of this wasteland is two thousand one hundred and nineteen meters at Hvannadalshnjukur, on the great Vatnajokull glacier. Vatnajokull is the largest ice mass in the world outside of Greenland and Antarctica.
...
A mid-oceanic ridge is an ocean floor structure composed of a series of submarine hills that rise toward a mountainous central zone. In the center of this zone is a comparatively narrow trench called an axial rift. Iceland sits astride the Reykjanes ridge. This ridge is an extension of the mid-Atlantic ridge, and is a constructive plate margin between the Eurasian plate and the (North) American plate.
...
The Upper Pleistocene phase, from .7 million years old to the end of the last glaciation, covers about 30000 square kilometers of Iceland. It is divided from the underlying Plio-Pleistocene phase by a thick layer of volcanic material indicative of the development of massive volcanic systems on the island. The Upper Pleistocene beds themselves show an alternation between subglacial eruptions and more typical lava flows, indicating interglacial periods. Rock from the Upper Pleistocene can be connected to existing volcanic systems which are either still active or dormant, rather than extinct (Saemundsson, 147)."

So, Iceland is part of mid-Atlantic ridge, and the mid-Atlantic ridge is a vast region of earth and the geothermal properties of this entire region might be somewhere in the ballpark hundred times higher than other parts of the earth. And it is regions like the mid-Atlantic ridge which make question whether Earth's average is actually .05 W/m.
Are these regions included in the this average and if they were, then what values were assign to these regions?

And as far as planets with 200 W/m, I wonder where Io or Europa average is.
