Sabah Health Director Reports No Impact on Air Quality from Indonesia's Mt. Ruang Eruption

Sabah Health director Datuk Dr. Asits Sanna has reported that there is no impact on Sabah's air quality from the eruptions of Indonesia's Mount Ruang volcano, despite some flight disruptions. Based on risk assessments, there is currently no need for the public to wear facemasks.

Satellite imagery has revealed a high concentration of sulfur dioxide (SO2) from the volcanic eruption, which has extended over 1,000 kilometers and affected Sarawak, Sabah, and Kalimantan. The sulfur dioxide gas can result in acid rain and air pollution downwind from the volcano, and can also lead to reduced visibility due to the formation of particulate matter. This reduction in visibility was the reason behind flight cancellations to East Malaysia on April 18.

The Malaysian Meteorological Department (MetMalaysia) issued a Significant Meteorological Information (SIGMET) 1, indicating ash clouds moving westerly at a speed of 30 knots from the surface to 55,000 feet and intensifying. However, Datuk Dr. Asits Sanna has reported that based on risk assessments, there is no current need for facemasks in Sabah.

Why this matters: The eruption of Mount Ruang in Indonesia has raised concerns about potential impacts on air quality and public health in neighboring regions. Sabah Health director's assessment provides reassurance to the public while highlighting the importance of monitoring and risk assessment in volcanic eruption situations.

The Air Pollutant Index (API) readings in Sarawak remain within the 'Good' to 'Moderate' range, and the eruption of Mt. Ruang has not had a direct impact on the ambient air quality in the state. The prevailing hot weather in the region is attributed to the inter-monsoon conditions expected to persist until May, and the public is advised to avoid open burning activities to prevent worsening the situation.

"Based on risk assessments, there is currently no need for the public to wear facemasks," Datuk Dr. Asits Sanna stated, addressing concerns about the potential impact of the volcanic eruption on Sabah's air quality. The Sabah Health director's report provides an update on the situation and offers guidance to the public in light of the ongoing volcanic activity in the region.

Key Takeaways

• Sabah's air quality unaffected by Indonesia's Mt. Ruang eruption, no need for masks.
• Satellite data shows high SO2 levels, affecting Sarawak, Sabah, and Kalimantan.
• Flight disruptions due to reduced visibility from volcanic ash, not air quality concerns.
• Sarawak's air quality remains in 'Good' to 'Moderate' range, not directly impacted.
• Ongoing monitoring and risk assessment to address public health concerns from eruption.
