Possible eruption of underwater volcano Ahyi, Mariana Islands archipelago

Geologic summary
Ahyi seamount is a large conical submarine volcano that rises to within 137 m of the sea surface about 18 km SE of the island of Farallon de Pajaros (Uracas) in the northern Marianas. Water discoloration has been observed over the submarine volcano, and in 1979 the crew of a fishing boat felt shocks over the summit area of the seamount followed by upwelling of sulfur-bearing water.
On April 24-25, 2001 an explosive submarine eruption was detected seismically from a seismic station on Rangiroa Atoll, Tuamotu Archipelago. The event was well constrained (+/- 15 km) at a location near the southern base of Ahyi; the summit of the seamount lies within the location uncertainty. (GVP)

so …it continues
The number of underwater volcanoes that are active at the present time is much higher than what volcanists think. Geologists who study underwater volcanoes around the planet have discovered huge number of such volcanoes. Is this has to due with the increase of co2 emissions?
