New Record Pollution Chokes Singapore

Pollution levels hit new record high as smog tightens chokehold on Singapore
The Pollutant Standards Index (PSI) hit 401 at 12:00 on Friday (04:00 UTC)—the highest in the country’s history, as smoky haze from fires in Indonesia shrouded the city state for a 3rd consecutive day.
A PSI reading above 300 is defined as “hazardous”, while Singapore government guidelines regard a PSI reading of above 400 over 24 hours as “Very Hazardous.”
A PSI of above 400 is defined: “May be life threatening to ill and elderly persons. Healthy people experience adverse symptoms that affect normal activity.”
Meantime, the government has warned that the haze could persist for weeks.
“We can’t tell how this problem is going to develop because it depends on the burning, it depends on the weather, it depends on the wind,” said the PM.
“It can easily last for several weeks and quite possibly it could last longer until the dry season ends in Sumatra which may be September or October.”
Parts of Malaysia have also been shrouded in “hazardous” pollution levels, prompting the authorities to close at least 300 schools in the south of the country.

Prelude to more serious events?
Our colleagues at EDRO believe that the collapse of Singapore may occur as a result of volcanic activity on the island of Sumatra. However, they have not disclosed any further detail.
