PPLS planning official Arif Firmanto said the breach was largely caused by land subsidence around the northern and western sections of the containment embankment. The subsidence has caused the mudflow to shift predominantly toward those areas, increasing pressure on the embankment.

An embankment at the Lapindo mudflow site in Sidoarjo, East Java, leaked early on Friday, prompting fresh concerns after water mixed with mud seeped dangerously close to the Porong highway and a busy railway line.The leak was detected at around 5:15 a.m. on the western side of the embankment in Siring sub-district, where local residents said a breach measuring nearly 2 meters had formed. They also said the mud level had risen to within 25 centimeters of the top of the embankment, raising fears of an overflow.
