What the coverage left out

None of the right-rated reports mention the transport ministry's report that ash from the eruption reached heights of up to 6,000m on the Java side and 15,000m on the Sumatra side. The right-rated reports also did not mention that schools in Jakarta and Lampung would use remote learning to counter health risks for students, as reported by state news agency Antara.
