WELLINGTON, Jan. 20 (Xinhua) -- Tsunami waves hit Tonga on Saturday, following a series of violent eruptions from underwater Hunga Tonga-Hunga Ha'apai volcano, 65 km north of the country's main island Tongatapu.
The tsunami had a significant impact on part of the foreshore of Tonga, with boats and large boulders washed ashore and shops along the coast damaged.
An interim telecommunication system has been set up in Tonga to allow its connection with the rest of the world using 2G networks, New Zealand's Ministry of Foreign Affairs and Trade said on Wednesday.
However, this connection will be limited and patchy covering about 10 percent of usual capacity and prioritizing voice and SMS communications, it said.
U.S. cable company SubCom said at least four weeks are needed to repair Tonga's cable connection.
Power in the Pacific islands country has been restored, with clean-up and damage assessments ongoing. Tongan authorities have been distributing relief supplies.
