From the Facebook page of the National Board for Disaster Management: Posts. The reference to "rain lava flood" means the mudflow caused by heavy rain mixing with volcanic ash. Excerpt from the Google translation:
The eruption of Mount Agung followed by an increase in the status of Awas and the determination of a radius of 8 -10 km as dangerous area by PVMBG on 27/11/2017 has consequently the community must evacuate out of radiius dangerous. There are 22 villages with estimated population in the dangerous radius of about 90,000 to 100,000 people. They have to evacuate because they live in disaster-prone areas whose threat is the danger of hot clouds, lava flows, falling rocks, incandescent rocks, and heavy ash rains. Very dangerous and deadly.
Based on preliminary data collected by Center for Operation Control (Pusdalops) BPBD Bali Province, the number of refugees per 29/11/2017 at 18.00 as many as 43,358 people spread in 229 point of refuge. Refugees are located in Buleleng Regency (5,992 inhabitants), Klungkung (7,790 inhabitants), Karangasem (22,738 people), Bangli (864 people), Tabanan (657 inhabitants), Denpasar City (1,488 inhabitants), Gianyar (2968 inhabitants), Badung soul), and Jembrana (312 souls). Governor of Bali has appealed to the community to evacuate around Karangasem only, no need far away because it will facilitate the handling of refugees, Nevertheless the people still evacuate out of Karangasem. Some even fled to Lombok.
Given the dangers of the eruption of Mount Agung is increasing, both primary hazards are pyroclastic material of Mount Agung eruption, or secondary dangers of rain lava flood. Also the handling of refugees and other impacts, the Regent of Karangasem has determined the emergency response situation in Karangasem regency for 14 days starting 27/11/2017 until 10/12/2017. The period of validation of this emergency response statement can be extended or shortened according to the need for emergency handling in the field.
The existence of these emergency status states, BNPB and BPBD have easy access in the field of human resources mobilization, equipment deployment, logistic deployment, immigration, excise, and quarantine, licensing, procurement of goods / services, management and accountability of money and / or goods, , and command to order agencies / institutions. This is necessary because disaster management must be fast and precise. Moreover, the handling of eruption of volcano is usually long.
There are still some people who do not want to evacuate due to several reasons, among others, still limited public understanding of the threat of eruption. Residents living in the disaster zone feel safe and do not need to evacuate. Some people consider that the eruption of Mount Agung is a spiritual event so that they surrender themselves completely to the power of God. There is also a reason to take care of livestock, farmland, and home. Some also tend to challenge themselves, for example by doing self-images in dangerous places. In social media there are already some young people who climb to the top of the mountain and soak in the rain lava flood. Obviously this is very dangerous.
The combination of these factors leads to differences in decisions among citizens. Some residents make a very safe decision, namely by conducting evacuation as soon as possible in accordance with the recommendations of PVMBG. On the other hand, there are also residents who make very dangerous decisions, ie they insist on staying in the danger zone.
