China News Service, Jan. 19 (Reuters) - Digicel, a Tonga telecom service provider, said on the 19th local time that its international call service had resumed.

On January 14, 2022 local time, an underwater volcano erupted in Tonga, a South Pacific island nation.

  On the other hand, internet connectivity could take weeks or more to recover due to damaged undersea cables, the report said.

  On the 14th and 15th local time, the submarine volcano on the Aha Apay Island in Tonga Hong erupted violently for two consecutive times and caused a tsunami, which once caused the country's network, telephone, and power to be interrupted.

Some experts believe that this may be one of the most powerful volcanic eruptions of the 21st century.
