A University College London kutat\u00f3inak tanulm\u00e1nya szerint 2022 m\u00e1rcius\u00e1ban gyors magma\u00e1raml\u00e1s zajlott az Azori-szigetekhez tartoz\u00f3 S\u00e3o Jorge alatt. N\u00e9h\u00e1ny nap alatt akkora mennyis\u00e9g\u0171 olvadt k\u0151zet gy\u0171lt \u00f6ssze a f\u00f6ld alatt, amely k\u00f6r\u00fclbel\u00fcl 32 ezer olimpiai \u00fasz\u00f3medence megt\u00f6lt\u00e9s\u00e9re lett volna elegend\u0151.<\/p>\n\n\n\n

A kutat\u00f3k megjegyezt\u00e9k, hogy a magma mozg\u00e1s\u00e1nak nagy r\u00e9sze szinte szeizmikus aktivit\u00e1s n\u00e9lk\u00fcl t\u00f6rt\u00e9nt. A f\u00f6ldreng\u00e9sek f\u0151 hull\u00e1ma csak azut\u00e1n kezd\u0151d\u00f6tt, hogy a magma m\u00e1r nem emelkedett tov\u00e1bb.<\/p>\n\n\n\n

A kutat\u00e1s vezet\u0151je, Stephen Hicks ezt \u201erejtett magmabet\u00f6r\u00e9snek\u201d nevezte. Elmond\u00e1sa szerint az olvadt k\u0151zet nagyon gyorsan haladt \u00e1t a f\u00f6ldk\u00e9regen, szinte \u00e9szrevehetetlen jelek mellett, ez\u00e9rt neh\u00e9z volt el\u0151re jelezni az esetleges kit\u00f6r\u00e9st.<\/p>\n\n\n\n

A vizsg\u00e1lathoz a tud\u00f3sok sz\u00e1razf\u00f6ldi \u00e9s \u00f3ce\u00e1nfen\u00e9ki szeizmom\u00e9tereket, valamint m\u0171holdas \u00e9s GPS-adatokat haszn\u00e1ltak. Meg\u00e1llap\u00edtott\u00e1k, hogy a sziget felsz\u00edne k\u00f6r\u00fclbel\u00fcl 6 centim\u00e9terrel emelkedett meg, ami meger\u0151s\u00edtette, hogy a magma behatolt a k\u00e9reg fels\u0151 r\u00e9tegeibe.<\/p>\n\n\n\n

Ennek ellen\u00e9re a magma nem t\u00f6rt a felsz\u00ednre. A tud\u00f3sok ezt a jelens\u00e9get \u201esikertelen kit\u00f6r\u00e9snek\u201d nevezik.<\/p>\n\n\n\n

A tanulm\u00e1ny t\u00e1rsszerz\u0151je, Pablo Gonz\u00e1lez a t\u00f6r\u00e9svonalat \u201eegyszerre aut\u00f3p\u00e1ly\u00e1hoz \u00e9s sziv\u00e1rg\u00e1shoz\u201d hasonl\u00edtotta. Elmagyar\u00e1zta, hogy a t\u00f6r\u00e9s seg\u00edtette a magma mozg\u00e1s\u00e1t, de egy\u00fattal meg is akad\u00e1lyozhatta a kit\u00f6r\u00e9st.<\/p>\n\n\n\n

A kutat\u00f3k \u00fagy v\u00e9lik, hogy az eredm\u00e9nyek hozz\u00e1j\u00e1rulhatnak a vulk\u00e1ni aktivit\u00e1s pontosabb el\u0151rejelz\u00e9s\u00e9hez \u00e9s a j\u00f6v\u0151beli kit\u00f6r\u00e9sek kock\u00e1zatainak jobb felm\u00e9r\u00e9s\u00e9hez.<\/p>\n\n\n\n
