8.8 x 1.7 x .2 == close to 3 CUBIC miles of lava. I wonder how much heat that released into the ocean and atmosphere as it developed...and its still active. 3 cubic miles of molten rock is a lot of rock and a lot of heat. A lot of CO2 and SO2 had to some out along with it too...
Spread out evenly over the land area of the planet, this would be a sheet of 2,000 degree material ~the thickness of a sheet of paper. If there are more of them, the numbers could start to get significant.
Curiously, the global warming crowd's models predicted more even warming, when in fact the warming is apparently concentrated much closer to the surface. Coincidence? I've always felt this planet's geologic history was primarily driven by three forces - impacts, volcanism, and the sun. Not too many large impacts in the recent past, but volcanism is still going strong and Mr. Sun has been more energetic the past couple hundred years.
[...]"This is presumed to be not only the biggest lava plateau in the Indian Ocean but also one of the biggest in the world," Ura said. "The vehicle also spotted hydrothermal eruptions on the northern part."
The flat plateau measures about 14 kilometers (8.8 miles) in length and 2.7 kilometers (1.7 miles) in width at a depth of about 2,700 meters (8,860 feet), according to the team from the university.
Ura said the plateau was covered with lava some 300 meters (980 feet) thick[...]
