Programul de vulcanologie globală: o fereastră către istoria înflăcărată a Pământului

Imaginați-vă o lume în care munții respiră foc și cenușă. Site-ul vulcanului. si. edu este exact locul unde sunt colectate toate datele despre astfel de evenimente. Este un proiect Smithsonian numit Global Volcanology Program, sau GVP. Ceea ce fac ei este să documenteze erupțiile din ultimii douăsprezece mii de ani. Nu doar marile dezastre, ci și cele mici. De ce este acest lucru important? Pentru că pentru a înțelege viitorul trebuie să cunoști trecutul.

Accentul programului este transferul rapid de informații. Când o erupție are loc undeva, observatorii locali o raportează și o lună mai târziu este publicat un buletin. Dar există și o retrospectivă. Ei colectează înregistrări istorice și date geologice. Toate acestea împreună ne ajută să ne pregătim pentru ceea ce se poate întâmpla mâine. Baza de date Vulcanii Lumii conține un catalog al tuturor munților activi timp de 12.000 de ani.

Ce se află în baza de date?

Există liste cu vulcani care au erupt în 2025. Puteți găsi rapoarte despre activitatea curentă. Există rezumate zilnice și săptămânale. De exemplu, a existat recent un raport al unei noi fisuri în sud-vest cu lavă în iunie 2024. Sau despre activitatea puternică a lacului de lavă din octombrie 2023 până în mai 2024. Pene de cenușă, anomalii termice, toate acestea sunt înregistrate. Nici măcar exploziile mici precum cea din 18 decembrie 2023 nu trec neobservate.

Interesant este că acum există aproximativ 40-50 de erupții în curs de desfășurare în același timp. În total, în ultimii 12 mii de ani au existat aproximativ 1222 de vulcani activi. Există 693 dintre ele în lume care aparțin Holocenului, ceea ce reprezintă 57 la sută din total. Sunt împrăștiate în 41 de regiuni diferite. Cele mai active țări sunt SUA Japonia Indonezia Rusia Chile. Uneori oamenii se întreabă câți oameni trăiesc în apropierea munților periculoși? Zece vulcani au mai mult de un milion de oameni pe o rază de cinci kilometri.

Unii munți ard foarte mult timp. Există 106 erupții care au durat cinci ani sau mai mult. Și vulcanul Yasur din Vanuatu ar fi erupt de mai bine de 750 de ani! Acest lucru este pur și simplu incredibil. Baza de date este actualizată în mod regulat. În decembrie 2025, a fost lansată versiunea 5. 3. 4. Tot în august, au lansat un nou proiect împreună cu USGS care oferă rapoarte zilnice scurte de luni până vineri.

• 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.
