Indonesia Warns Of Health Risks To Elderly From Volcanic Ash

JAKARTA, Sept 7 (NNN-ANTARA) -- Indonesia’s Health Ministry said some 3.3 million elderly people in areas surrounding Mount Anak Krakatau, including Banten, South Lampung, Jakarta and parts of West Java, face health risks from volcanic ash, highlighting the urgency of mitigation efforts, reported Antara news agency.

“The sharp silica particles contained in volcanic ash make it dangerous to the lungs, eyes and skin. When mixed with water, the ash can harden like cement, so improper cleaning can actually increase the risks,” the ministry’s Director of Health Services for Vulnerable Groups, Imran Pambudi, said here on Monday.

Pambudi stressed that exposure to volcanic ash can cause several health problems, including acute respiratory infections, breathing difficulties, and exacerbation of asthma and chronic obstructive pulmonary disease (COPD). It can also increase cardiovascular risks, including the risk of heart attacks and strokes.

According to Pambudi, the effects of volcanic ash can be felt immediately, while smoke from forest and land fires tends to have a longer-term impact on the respiratory and cardiovascular systems.

“The eyes can become sore, watery and easily irritated, while the skin can become itchy and inflamed. Elderly people may also experience confusion and reduced concentration following prolonged exposure. Trauma from sudden evacuation and social isolation can add to the psychological burden,” he added.

Mount Anak Krakatau has erupted several times over the past two decades, he said.

In 2018, an eruption triggered a tsunami that killed more than 400 people.

Anak Krakatau, located in the Sunda Strait between Java and Sumatra, has remained at Level III (Alert) since July 2, the second-highest level in Indonesia’s four-tier volcano alert system, with a three-kilometre exclusion zone in place around the volcano.

Meanwhile, in September 2026, volcanic ash from the volcano spread to parts of Lampung, Banten, Jakarta and West Java.

According to Pambudi, eruptions pose health risks to the public, particularly elderly people, who are among the most vulnerable groups.

Hence, comprehensive mitigation measures must be carried out, he said.

People need to use masks and protective eyewear, seal any openings in their homes to prevent ash from getting in, and clean the ash properly.

He also reminded families and caregivers of elderly people to ensure medications remain readily available, to monitor any warning signs, and to provide emotional support.

Moreover, healthcare facilities need to provide oxygen concentrators, medications, salves, eyedrops and personnel ready for emergency evacuations, he said.
