Do volcanic eruptions release Mercury?

Does Mercury have a lot of volcanic activity?

Does lava contain Mercury?
Researchers had suspected that mercury boils out of hot magma, the big surprise was just how much mercury escapes from volcanoes. Measurements made on just one part of the Masaya volcano in Nicaragua have shown that about 7 tons of natural volcanic mercury escapes into the atmosphere from this vent each year.
How did volcanoes form on Mercury?
“Mercury has a much smaller mantle, where radioactive decay produces heat, than those other planets, and so it lost its heat much earlier. As a result, Mercury began to contract, and the crust essentially sealed off any conduits by which magma could reach the surface.”
