Mount Bromo, East Java

Mount Bromo

Depending on the degree of volcanic activity, the Indonesian Centre for Vulcanology 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. The origin of the ritual lies in the 15th century legend where a princess named Roro Anteng started the principality of Tengger with her husband, Joko Seger. The couple were childless and therefore beseeched the assistance of the mountain gods. The gods granted them 24 children but stipulated that the 25th child, named Kesuma, must be thrown into the volcano as a human sacrifice. The gods' request was implemented. The tradition of throwing sacrifices into the volcano to appease these ancient deities continues today and is called the Yadnya Kasada ceremony. Though fraught with danger, some locals risk climbing down into the crater in an attempt to recollect the sacrificed goods that they believe could bring them good luck.
On the Segara Wedi sand plain sits a Hindu temple called Pura Luhur Poten. The temple holds a significant importance to the Tenggerese scattered across the mountain villages, such as Ngadisari, Wonokitri, Ngadas, Argosari, Ranu Prani, Ledok Ombo and Wonokerso. The temple organises the annual Yadnya Kasada ceremony which lasts for about one month. On the 14th day, the Tenggerese congregate at Pura Luhur Poten to ask for blessings from Ida Sang Hyang Widi Wasa and the God of Mahameru. Then the crowd proceeds along the crater edges of Mt Bromo where offerings are thrown into the crater. The major difference between this temple and Balinese ones are the type of stones and building materials. Pura Luhur Poten uses natural black stones from volcanoes nearby, while Balinese temples are mostly made from red bricks. Inside this pura, there are several buildings and enclosures aligned in a mandala zone composition.

On Tuesday, 23 November 2010, 16.30 WIB, the Indonesian Centre of Vulcanology and Geology Hazard Mitigation (CVGHM) confirmed the activity status of Mount Bromo at "alert" due to increasing tremor activity and shallow volcanic earthquakes at the mountain. Concerns were raised that a volcanic eruption might be likely to occur. 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 remaining part of 2010.

Bromo started to erupt 2010.

ash on Friday 26 November -

The Tengger Caldera was still active in late January 2011, the activity being characterised by fluctuating ongoing eruptions. On 23 January 2011 the Indonesian Centre for Volcanology and Geological Hazard Mitigation (Pusat Vulkanologi dan Mitigasi Bencana Geologi) reported that since 19 December 2010 volcanic ash and incandescent material had been thrown up by eruptive activity resulting in a heavy rain of material that fell around the crater. Continuous eruptions on 21 January caused a thin ash fall mainly in the village areas of Ngadirejo and Sukapura Wonokerto in Probolinggo district. The impact of a heavy rain of volcanic ash from eruptions since 19 December 2010 resulted in disruption of normal activities. By early 2011 concerns were being raised concerning the effect upon the local economy and the potential for long term environmental and health problems amongst the residents in the locality surrounding Mount Bromo. Due to high seasonal rainfall in January 2011 the potential for lahar and lava flow was raised due to the deposits of volcanic ash, sand and other ejected material that had built up. Seismic activity was dominated by tremor vibration and reports of visual intensity and sounds of eruption continued to be reported from the mountain monitoring facility, Bromo Observation Post. People living on the banks of the Perahu Ravine, Nganten Ravine and Sukapura River were alerted to the possibility of lava flows, especially when it was raining heavily in the area around Cemorolawang, Ngadisari and Ngadirejo. Eruptions and volcanic tremors were reported on 21 January and 22 January with activity subsiding on 23 January 2011. On 23 January 2011 at 06:00 am the alert status at Mount Bromo remained at (Level III).
The Indonesian Centre for Volcanology and Geological Hazard Mitigation 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.
Deformation measurement using electronic distance measurement equipment compared observations at designated measuring points; POS-BRO, POS-KUR and POS-BAT during the period 25 November 2010 - 20 December 2010 with observations from the period 21 December 2010 - 30 December 2010 indicated the shortening of the distance from the POS-BAT, or inflation. Observations between 30 December 2010 to 23 January 2011 were reported as relatively stable.
