The Regent of Lumajang Thoriqul Haq asked the people around the river basin to be aware of the cold lava flood of Mount Semeru after the eruption and launching hot clouds of avalanches.
"The rain that flushed the Mount Semeru area caused a cold lava flood that brought the remaining material from the eruption," said the Lumajang Regent, who is usually called Cak Thoriq, in the local district, Tuesday, December 6.
The eruption of Mount Semeru, which was accompanied by a 13-kilometer avalanche of hot clouds (APG) that occurred on Sunday (4/12), left a number of problems.
"In addition to the material covering most areas of Kajar Kuning Hamlet, Sumbermujur Village, Candipuro District, the material carried by cold lava also flows towards Besuk Bang, Tempursari District," he said as quoted by Antara.
He said this was different from the eruption incident in 2021 because the cold lava also flowed towards Tempursari District, so it needs to be watched out for because it has never happened in recent years.
"There are cold clouds that lead to Tempursari, we received news of the direction of the lava leading there, last year it was not. The flow broke into three, one of which was Besuk Bang, so it also needs to be anticipated," he said.
Cak Thoriq explained that the material vomited by Mount Semeru on December 4, 2022 also had an impact on increasing material on the lava flow route of Mount Semeru.
"Therefore, we will immediately carry out cleaning and normalization at points that are considered important to be cleaned immediately, one of which is on Jalan Dusun Kajar Kuning and several runoff bridges that have been covered by cold lava material," he said.
He said officers will work soon this Tuesday, but his party will also consider the safety of officers because the eruption material and APG are still hot.
"We urge people who have no interest not to approach the cold lava lane area, especially when heavy rains flush the peak area," he said.
