Rinjani-20160801-1120

Mount Rinjani eruption closes Lombok Airport and may affect Bali’s Airport tonight

As previously expected, Mount Rinjani’s eruption has resulted in closure of Lombok Praya International Airport (LOP/WADL) due to volcanic ash, but the ASHTAM issued by VAAC Darwin at 1120UTC may result in service disruption at Bali’s Ngurah Rai Airport (DPS/WADD) as well.

Mount Rinjani Eruptions – Some flight disruptions to Bali and Lombok possible

Mount Rinjani at Lombok island erupted today and volcanic ash plumes were observed to have reached high altitudes. Initial reports suggested that the ash plume could reach 32000 feet and that it would spread south to southwest from the volcano.

LOP-Compo
Earlier (now revised) volcanic ash dispersal projections had a wide extent and predicted to reach 32,000ft, causing worries at several airlines.

The Volcanic Ash Advisory Center in Darwin ash issued several ashtams on this volcano today. The current one at the time of this article’s publication is:

Eruptions have ceased and the ash dispersal projections has been revised as mentioned above. Volcanic ash is predicted to reach Lombok International Airport (LOP/WADL) by no late than 8pm local time (1200UTC), between the surface and 10,000 feet.

LOP-Compo2
Current ash dispersal projection with further extent predicted for 1200UTC.

The earlier projections caused some worries at some airlines, notably Indonesia Air Asia and Virgin Australia who rerouted flights to bypass the ash dispersal projections. One Virgin Australia flight from Brisbane to Bali reportedly landed in Darwin, possibly to take up extra fuel to allow for the rerouting.

A meeting is now taking place for aviation stake holders (notably AirNav and the Meteorology office, BMKG), to consider whether or not to close Lombok Praya Airport and if so, when.
