More than 2,100 People Are Evacuated as an Indonesian Volcano Spews Clouds of Ash

More than 2,100 people living near an erupting volcano on Indonesia's Sulawesi Island were evacuated Friday due to the dangers of spreading ash, falling rocks, hot volcanic clouds and the possibility of a tsunami.

Indonesia's Center for Volcanology and Geological Hazard Mitigation recorded at least three eruptions since Friday afternoon, with the maximum height of the eruption column reaching 1,200 meters (3,900 feet).

An international airport in Manado city, less than 100 kilometers (60 miles) from the erupting Mount Ruang, is still temporarily closed as volcanic ash was spewed into the air.

Satellite imagery from the Meteorology, Climatology and Geophysics Agency shows the ash has spread to the west, northwest, northeast and southeast, covering Manado and North Minahasa, according to a statement from Indonesia’s Transportation Ministry.

“We are still monitoring developments in the eruption of Mount Ruang and coordinating with relevant stakeholders ... to anticipate the necessary actions to ensure flight safety, security and comfort,” said Ambar Suryoko, head of the regional airport authority.

More than 11,000 people were told to leave their homes that were located in the affected area. A joint team from the local authorities combed the villages surrounding the volcano and evacuated residents to safer areas by boat.

Officials worry that part of the volcano could collapse into the sea and cause a tsunami, as happened in an eruption there in 1871.

Houses, roads and other buildings were covered by gray volcanic ash, and many roofs were broken by debris spewed from the eruption.

Mount Ruang saw at least five large eruptions Wednesday, causing the Center for Volcanology and Geological Hazard Mitigation to issue its highest level of alert. People were ordered to stay at least 6 kilometers (3.7 miles) from the 725-meter (2,378-foot) mountain.

The observation from the agency on Friday said white smoke was rising from the main crater with medium to thick intensity.

East of the volcano, Tagulandang Island could be at risk if a collapse occurred. Its residents were among those being told to evacuate. Indonesia’s National Disaster Mitigation Agency said residents would be relocated to Manado, a journey of 6 hours by boat.

Indonesia, an archipelago of 270 million people, has 120 active volcanoes. It is prone to volcanic activity because it sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
