Eruption of mount Kelut: SO2 and ash from IASI-B at 14:45 UTC (14 February 2014).

The Kelut eruption on the island of Java has produced a large ash and SO2 cloud that has been tracked by polar orbiting satellite instruments (IASI and GOME-2 onboard MetOp-A and MetOp-B, OMI on Aura, and AIRS on Aqua). The ash has reached high altitudes where commercial aircraft fly and is a significant hazard to aviation. Three airports on Java have been closed and air routes from Australia to Singapore, Bangkok and beyond affected.

ESA and its partners are maintaining a constant vigil and providing satellite notifications to the relevant authorities through its SACS system.


The Support to Aviation Control Service (SACS) hosted by the Belgian Institute for Space Aeronomy aims at supporting the Volcanic Ash Advisory Centers, like Toulouse VAAC and London VAAC.

This is achieved by delivering NEAR REAL-TIME data derived from satellite measurements regarding volcanic emissions by UV-visible (OMI, GOME-2A, GOME-2B) and InfraRed (AIRS, IASI-A, IASI-B) instruments.

In case of volcanic eruptions, notifications from our multi-sensors system are sent out by email to interested parties.

   

 DISCLAIMER:   SACS is a free service that provides SO2 notifications
in case of exceptional concentrations detected by satellite instruments.
The usage of the SACS notifications, whether or not these happen to be
"true" or "false" notifications, is entirely in the hands of the Users.
The SACS developers disclaim liability for any kind of use or misuse
of the SACS information, regardless of the application.
