Recommendations
2. Masyarakat dan pengunjung/wisatawan tidak memasuki Kawah Sibangor Tonga, Kawah Sibangor Julu, dan kawah-kawah lainnya yang terdapat disekitar G. Sorikmarapi untuk menghindari potensi bahaya dari semburan lumpur dan/atau gas beracun yang dapat terjadi secara tiba-tiba.
3. Seluruh pihak agar menjaga suasana yang kondusif di masyarakat, tidak menyebarkan narasi bohong (hoax), dan tidak terpancing isu-isu yang tidak jelas sumbernya. Masyarakat harap selalu mengikuti arahan dari Pemerintah Daerah.
4. Pemerintah Daerah agar senantiasa berkoordinasi dengan Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG), Badan Geologi di Bandung atau dengan Pos Pengamatan G. Sorikmarapi di Desa Sibangor Tonga, Kecamatan Puncak Sorikmarapi, Kabupaten Mandailing Natal, Provinsi Sumatera Utara.
