The activity of Rinjani volcano on Lombok island, has not waned in recent days. The ash plume spotted by local observers and VAAC Darwin, traveling to the west and the island of Bali, has disrupted flights and Ngurah Rai International airport.

This Tuesday, 3 October, it was closed from 7:30 to 11:30, affecting 11 international flights of Virgin Australia airlines, Cathay Pacific and KLM and nine domestic flights. The situation should be reviewed this November 4 with three closed airports: Ngurah Rai on Bali, Selaparang Airport on Lombok and Airport Blimbingsari in Banyuwangi, East Java.

On Lombok, seven villages north of the island, were covered with the ashes of Rinjani and BPDB - West Nusa Tenggara Disaster Mitigation AGENCY- has prepared some 4,000 dust masks and evacuation scenarios for areas affected.

NOAA Ship Okeanos Mission conducted Explorer maps in the Papahanaumokuakea Marine National Monument, an area east of Pearl and Hermes in August 2015. An unnamed submarine volcano, already spotted by satellite bathymetry, was reviewed and confirmed by the bathymetry of underwater robots.

Its height exceeds of 2818 meters the seabed, plunging to less than 5,200 meters; its width is 14.8 km. following a NW-SE axis, and he have a form in cone or pyramid, with a well-defined peak.
