On this day, 114 years ago, on January 30, 1911 (January 1, 1911 in the lunar calendar), Mount Tal erupted in the southwestern part of Luzon Island in the Philippines. In the southwest of Luzon Island in the Philippines, there is a 244-square-kilometer Tal Lake with a water depth of 170 meters. It is actually a volcanic crater. There is an island in the center of the lake, Tar Volcano, which is only 300 meters high and is the lowest and smallest active volcano on earth. Since 1572, the Tar Volcano has erupted more than 20 times, constantly changing the appearance of islands and lakes. On January 30, 1911, the Tar Volcano burst halfway, and smoke rose to a height of 10,000 meters. Mushroom clouds similar to the explosion of an atomic bomb blocked the sun., volcanic ash spread over an area of 5000 square kilometers. After the volcanic eruption, most of the Tar Volcanic Island was destroyed, leaving only a little exposed to the lake, and the entire lake deepened. Hot debris destroyed villages and towns around Lake Tar, killing 1400 people. Since then, Mount Tar has erupted every few years. The most violent was the eruption on September 28-30, 1965, which covered 60 square kilometers with volcanic ash as thick as 25 centimeters and accumulated 70 million cubic meters, causing hundreds of casualties.
