Philippine eruption A major blow to agriculture Warning about re-eruption January 15 at 18:52
The eruption of a volcano near Manila, the capital city of the Philippines, has spread its impact, with massive deposition of volcanic ash causing great damage to crops. Japanese experts have pointed out that "there is a great possibility of another major eruption," and Filipino officials remain vigilant.
Thar volcano on Luzon, about 60 km south of Manila, the Philippines' capital, erupted this month, leaving about 43,000 people evacuated and a large amount of ash deposited in rice, bananas and coffee. Agricultural crops such as are greatly damaged.
The Ministry of Agriculture of the Philippines has revealed that over 2,770 hectares of agricultural land has been damaged so far, amounting to about 1.2 billion yen in Japanese yen.
In the province of Cavite around the volcano, pineapple fields were entirely covered with black ash, and ash was found to stick to the pineapple before harvesting.
A pineapple farmer said, "I can't harvest anymore. If I can harvest it, it will just rot if no tourists come."
In the future, Professor Hiroyuki Kumagai of Nagoya University Graduate School, who has helped to strengthen the monitoring system for Taal Volcano, said, "There is a good chance that another large eruption will occur. In the past, there were cases where the eruption was only several days, In some cases, it has been intermittent for about a year, and I don't know how long it will take. "
He pointed out that the eruption could cause the volcano to collapse on a large scale, causing a large amount of sediment to flow into the lake, causing the lake's water to rush to the other side of the lake.
The Philippine authorities have maintained the vigilance level of the eruption at Level 4, the second highest, and remain vigilant.
Expert "Eruption likely again"
"There is a good chance that another major eruption will occur again," said Professor Hiroyuki Kumagai of Nagoya University Graduate School, which has been helping strengthen the local monitoring system since 2009 on the eruption of the Thar volcano in the Philippines.
Taal volcano is a volcanic island floating on a lake called `` Tahl Lake '', and according to Professor Kumagai, residence on the island is prohibited, but in fact many people live and tourists can visit That is.
In addition, Tar volcano is characterized by a high frequency of eruptions, with an indication that the probability of erupting within 30 years is 88%.
In 1911, an explosive eruption killed more than 1,300 people, and in the 1965 eruption, about 150 people died, and pyroclastic flows flowed several kilometers to the opposite shore, causing serious damage. Is that.
No large eruptions have been observed since the 1977 eruption, but Japanese research institutes and other organizations have strengthened the surveillance system and have been vigilant for the next eruption.
