Recommendations
2. Masyarakat yang berada di luar radius 500 m dari G. Ruang diharap tenang, beraktivitas seperti biasa, tidak terpancing isu-isu tentang erupsi G. Ruang dan tetap mengikuti perkembangan aktivitas G. Ruang melalui aplikasi MAGMA Indonesia yang dapat diunduh di Google Playstore atau melalui website https://magma.esdm.go.id, Website PVMBG https://vsi.esdm.go.id, dan Website Badan Geologi https://geologi.esdm.go.id serta media sosial PVMBG (Facebook, X, dan Instagram @pvmbg_).
3. Pemerintah Daerah, BPBD Provinsi dan Kabupaten agar senantiasa berkoordinasi dengan Pos Pengamatan Gunung Api Ruang, Desa Tulusan, Kecamatan Tagulandang, Kabupaten Sitaro, Sulawesi Utara atau Badan Geologi di Bandung.
