Küresel Volkanoloji Programı: Dünyanın ateşli tarihine açılan bir pencere

Dağların ateş ve kül soluduğu bir dünya hayal edin. Volkan web sitesi. si. edu tam olarak bu tür etkinliklerle ilgili tüm verilerin toplandığı yerdir. Bu, Küresel Volkanoloji Programı veya GVP adı verilen bir Smithsonian projesi. Yaptıkları şey son on iki bin yıldaki patlamaları belgelemek. Sadece büyük felaketler değil, aynı zamanda küçük felaketler de var. Bu neden önemli? Çünkü geleceği anlamak için geçmişi bilmek gerekir.

Programın odak noktası bilginin hızlı aktarımıdır. Bir yerde bir patlama meydana geldiğinde yerel gözlemciler bunu rapor ediyor ve bir ay sonra bir bülten yayınlanıyor. Ama bir de retrospektif var. Tarihsel kayıtları ve jeolojik verileri toplarlar. Bütün bunlar birlikte yarın olabileceklere hazırlanmamıza yardımcı oluyor. Dünya Volkanları veritabanı, 12.000 yıl boyunca aktif olan tüm dağların bir kataloğunu içerir.

Veritabanında neler var?

2025'te patlayan yanardağların listesi var. Güncel faaliyetlerle ilgili raporlar bulabilirsiniz. Günlük ve haftalık özetler var. Örneğin, yakın zamanda Haziran 2024'te güneybatıda lavlarla birlikte yeni bir çatlağın rapor edildiğine dair bir rapor vardı. Veya lav gölünün Ekim 2023'ten Mayıs 2024'e kadar güçlü aktivitesi hakkında. Kül bulutları, termal anormallikler, tüm bunlar kaydediliyor. 18 Aralık 2023'tekine benzer küçük patlamalar bile gözden kaçmıyor.

İlginçtir ki, şu anda aynı anda yaklaşık 40-50 patlama devam ediyor. Toplamda, son 12 bin yılda yaklaşık 1222 aktif yanardağ var. Dünyada bunlardan 693 tanesi Holosen dönemine ait olup, toplamın yüzde 57'sini oluşturur. 41 farklı bölgeye dağılmış durumdalar. En aktif ülkeler ABD Japonya Endonezya Rusya Şili'dir. Bazen insanlar tehlikeli dağların yakınında kaç kişinin yaşadığını soruyor? On volkanın beş kilometrelik yarıçapında bir milyondan fazla insan yaşıyor.

Bazı dağlar çok uzun süre yanar. Beş yıl veya daha uzun süren 106 patlama var. Ve Vanuatu'daki Yasur Yanardağı 750 yıldan fazla bir süredir patlıyor olabilir! Bu kesinlikle inanılmaz. Veritabanı düzenli olarak güncellenmektedir. Aralık 2025'te 5.3.4 sürümü yayınlandı. Yine Ağustos ayında USGS ile birlikte pazartesiden cumaya kısa günlük raporlar sağlayan yeni bir proje başlattılar.

• name: Description content: The Global Volcanism Program (GVP) seeks better understanding of all volcanoes through documenting their eruptions--small as well as large--during the past 12,000 years. The range of volcanic behavior is great enough, and volcano lifetimes are long enough, that we must integrate observations of contemporary activity with historical and geological records of the recent past in order to prepare wisely for the future. The contemporary focus of the GVP is evident in the central role we play in the rapid dissemination of on-going eruption reports from local observers through our monthly Bulletin of the Global Volcanism Network. Our retrospective effort to document Earth's volcanic eruptions of the last 12,000 years has led to development of comprehensive databases and an archive of relevant maps, photos, and documents. Through these two complementary approaches we attempt to provide a context in which any individual volcano's benefits and dangers can be usefully assessed.
