On this day, 31 years ago, on September 19, 1994 (August 14, 1994 in the lunar calendar), a volcano in Papua New Guinea erupted. On September 19, 1994, the Tavorol and Varken volcanoes located in the Eastern New Britain Province of Papua New Guinea erupted again on September 19 after being silent for more than half a century. A large amount of grey smoke and hot gas accompanied by storms and storms instantly swallowed the once heavily transported Port Moresby, and more than 30,000 residents instantly became homeless refugees. A few days later, the "smoke dragon" spewing from the crater still shrouded the important port town of Labur. Earthquake warning On the night of September 18, the town of Labur was unusually dark, and the distance between heaven and earth seemed to be grasped by a pair of invisible hands, pulling tighter and tighter, as if it wanted to crush all living things. People here are not sleepy at all. They are nervously evacuating this home that will no longer belong to them in accordance with the government's arrangements. That morning, an earthquake measuring 5.1 on the Richter scale occurred here, and the earth kept shaking throughout the day, playing a prelude to the eruption of the volcano. At 6:30 a.m. on the 19th, there was loud thunder and heavy rain. One lightning bolt after another illuminated the night sky as day. A teenage boy suddenly rushed out of his house to chase the evacuating crowd. Unfortunately, he was knocked down by an oncoming car and fell on the road. Another adult man was knocked down by lightning and died instantly. They became the first victims of this natural disaster. Fortunately, 99% of the town's residents evacuated early, reducing casualties to a minimum. The volcano is angry. Huge white smoke clouds carrying dust and heat rushed up from several volcanic craters at the same time and shot several kilometers into the sky. Suddenly, all communications were interrupted, planes stopped taking off, ships stopped sailing, and Labur was buried in dust and became a dead port. Volcanic ash continued to fall, reaching 30 inches in two days, blocking all roads and collapsing many houses. Refugees evacuated to nearby villages are anxiously waiting for relief supplies from the government, especially clean drinking water, otherwise infectious diseases will soon spread. The Crater Harbor is located in the tropics of Papua New Guinea, with a high humidity and rainy climate, is rich in coconut and coffee. Forest and mineral resources are also rich. Labur is the sixth largest town in this South Pacific island country and an important shipping hub. Most of the coconuts, coconut products, wood and other goods produced here are exported from this port. Although people knew that Labur was "sitting" on the crater, they were reluctant to give it up. In this harbor surrounded by mountains, there are at least 6-7 ever-changing volcanic craters overlooking it. Volcanoes erupted in 1791, 1797, 1850, 1878 and 1937. The worst was in 1937, which claimed more than 500 lives. However, with the advancement of science and technology and economic development. By the mid-1980s, the port had become busier, and modern forecasting methods provided safety for people. However, the threat of volcanoes has not been completely eliminated. After the volcanic eruption in the Rabur area, the government of Papua New Guinea took all effective measures to rescue the victims. Despite near-zero visibility, large transport aircraft sent by the government were venturing into taking off and landing, bringing in large quantities of blankets, tents, clothing, medicine and food. The Prime Minister visited the site in person on the same day and decided to cancel the original plan to participate in the UN General Assembly and go all out to organize disaster relief. At the same time, the issue of relocation has become a major topic of discussion among people. Many people believe that although technology can ensure the safety of people to a certain extent, this town will always be in danger. However, it is not easy to relocate? It is estimated that rebuilding various commercial facilities in such a port town requires at least US$93 million in investment. No one can easily take out such a huge amount.
