Mount Bromo is an active volcano and part of the Tengger massif, in East Java, Indonesia. At(7,641 ft) it is not the highest peak of the massif, but is the most well known. The massif area is one of the most visited tourist attractions in East Java, Indonesia. The volcano belongs to the Bromo Tengger Semeru National Park. The name of Bromo derived from Javanese pronunciation of Brahma, the Hindu creator god. Sulfur is collected from inside the caldera by workers.
Mount Bromo sits in the middle of a vast plain called the "Sea of Sand", a protected nature reserve since 1919. The typical way to visit Mount Bromo is from the nearby mountain village of Cemoro Lawang. From there it is possible to walk to the volcano in about 45 minutes, but it is also possible to take an organised jeep tour, which includes a stop at the viewpoint on Mount Penanjakan (99,088 ft). The viewpoint on Mount Penanjakan can also be reached on foot in about two hours.
Depending on the degree of volcanic activity, the Indonesian Centre for Volcanology and Disaster Hazard Mitigation sometimes issues warnings against visiting Mount Bromo.
On the fourteenth day of the Hindu festival of Yadnya Kasada, the Tenggerese people of Probolinggo, East Java, travel up the mountain in order to make offerings of fruit, rice, vegetables, flowers and sacrifices of livestock to the mountain gods by throwing them into the caldera of the volcano.
- 2004 eruptions Mount Bromo erupted in 2004. That eruptive episode led to the death of two people who had been hit by rocks from the explosion.
- 2010 eruptions As a precaution local residents and tourists were instructed to remain clear of an area within a radius of three kilometres from the caldera and refugee encampments were erected. The area surrounding the Teggera caldera of Bromo remained off-limits for visitors throughout the remainder of 2010.
- 2011 eruptions The Indonesian Centre for Volcanology and Geological Hazard Mitigation (CVGHM) reported on 13 January 2011, that deformation using tiltmeter measurements indicated an inflation at rate of 5 micro radians between 25 November 2010 and 14 December 2010 and a relatively stable since 15 December 2010 both on Radial Components and Tangential Components.
- 2015 Eruption Mount Bromo has shown signs of increasing activity since early November, when the amount of smoke coming out of the crater intensified.[12] By late November Mount Bromo began to eject ashes into the air.[13] Indonesian Volcano Monitoring Bureau (PVBMG) issued a warning that forbade people from climbing Mount Bromo. Later the warning was extended into a 1 km exclusion zone, before eventually extended into wider range which virtually barred visitors from coming down into the caldera floor, which is popularly known as Sandsea.
Bromo started to erupt ash on Friday 26 November 2010.
