The volcanoes on Venus aren't dead, say astroboffins, they're merely resting, pining for the planet's lava fjords

Makes sense

37 volcanos don't suddenly go dead in a few million years in a 5 billion year old planet that's almost the same size - and therefor probably has almost the same core heat - as earth. Venus doesn't have plate tectonics (as far as we know) so unlike on earth volcanos won't die as the crust moves past the hotspot , they'll probably simply build up huge pressures until they blow - rinse and repeat for a billion years. Plus the 400C surface temp of venus will make the rocks somewhat more flexible and deformable than on earth so making any eruptions more likely all other things being equal.
