Nearly a week has passed since the eruption of the underwater volcano on the Aha Apai Island in Tonga, and the people of Tonga have begun to rebuild their homes.
A local environmental protection organization in Tonga said on the 21st that after the volcanic eruption, the power supply in Tonga was completely interrupted. Local environmental groups decided to teach locals how to assemble solar panels, relying on solar cells to cope with post-disaster power shortages. According to Shikulu, the head of the environmental protection organization, solar cells can provide LED lighting for ordinary households without power, charge mobile phones and provide basic household electricity.
Shikuru said that in addition to the power supply problem, Tonga's urgent need to solve the communication problem. After the submarine optical cable was cut off, most Tongans lost contact with the outside world, and Tonga became an "information island". It also made people realize that satellite data services should be developed to ensure that people can still communicate normally after natural disasters.
As the volcanic ash covered the whole of Tonga, the local drinking water, soil, fishery and animal husbandry were seriously affected. According to the news released by the United Nations on the 20th, after the eruption of the volcano, the United Nations staff in Tonga continued to test the local water quality. At present, the local area is still facing the threat of seawater inversion and acid rain. At present, most Tonga people mainly drink bottled water. In addition to facing water and food shortages, the local area is also facing severe fuel shortages.
After disaster, solar and wind clean energy are important during rebuilt, which has shown both after American huge storm, Tonga volcano or the COVID 19.
