Karsten Schmidt<p>I've been fascinated by Mt. St.Helens ever since I first saw the eruption on TV in 1980 as a kid in East Germany, and later watching an impressive documentary at the IMAX in Seattle in 1995. It took me another 21 years, until 2016, to set foot on the mountain myself and I visited again many times over the following 5 years... truly one of the most interesting places I've ever been to, witnessing both geology and biology evolving in realtime...</p><p>So, tonight on the 45th anniversary of the (in)famous eruption, it's time to watch this old Minute by Minute episode again:<br><a href="https://www.youtube.com/watch?v=fArB5Jz2wos" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">youtube.com/watch?v=fArB5Jz2wo</span><span class="invisible">s</span></a></p><p><a href="https://mastodon.thi.ng/tags/MtStHelens" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MtStHelens</span></a> <a href="https://mastodon.thi.ng/tags/Mountains" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mountains</span></a> <a href="https://mastodon.thi.ng/tags/Volcano" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Volcano</span></a> <a href="https://mastodon.thi.ng/tags/Eruption" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Eruption</span></a></p>

kīpuka<p>Depuis le fort séisme du 13 mars, on entend beaucoup parler de la situation dans les Champs Phlégréens, le vaste système volcanique situé sous l’agglomération de <a href="https://social.sciences.re/tags/Naples" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Naples</span></a>. Souvent avec les mots « supervolcan » ou « superéruption » pour faire peur… Rétablissons donc quelques faits.<br>– Si l’on s’en tient strictement à la définition, il n’y a jamais eu de superéruption des Champs Phlégréens. Ce terme correspond à une <a href="https://social.sciences.re/tags/%C3%A9ruption" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>éruption</span></a> avec un index d’explosivité volcanique (VEI) de 8, correspondant à un volume éjecté > 1000 km³. Or le <a href="https://social.sciences.re/tags/volcan" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>volcan</span></a> a connu au maximum des éruptions de VEI 7 (> 100 km³). Ça reste une éruption catastrophique, on est d’accord, mais pas « super » (on sent là tout l’absurde du préfixe…).<br>– Si le volcan a bien connu une éruption de VEI 7 dans la période géologique « récente » (l’éruption campanienne, il y a environ 39 000 ans), ainsi qu’une de VEI 6 (> 10 km³, le tuf jaune napolitain, vers 15 000 ans), son activité depuis est faite d’événements bien plus modestes.<br>– Ainsi, la toute dernière éruption des Champs Phlégréens, en 1538, est seulement classée VEI 2 et n’a fait que construire un petit cône, le Monte Nuovo. L’apparition d’un tel cône dans une zone aujourd’hui densément peuplée serait assurément problématique, mais on est loin du caractère catastrophique d’un effondrement de caldeira avec expulsion de dizaines de kilomètres cubes de magma !<br>Voilà, la prochaine fois que quelqu’un mentionne « l’imminente superéruption du supervolcan de Naples », vous pouvez lui envoyer un lien vers ce message d’utilité publique !<br><a href="https://social.sciences.re/tags/Italie" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Italie</span></a></p>
kīpuka<p>Je me suis amusé à comparer deux images webcam de l'<a href="https://social.sciences.re/tags/%C3%A9ruption" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>éruption</span></a> qui a toujours lieu au <a href="https://social.sciences.re/tags/K%C4%ABlauea" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Kīlauea</span></a> (Hawaï). La première date du 26 mars, lors de l'épisode 15, et la seconde du 14 avril, c'est-à-dire de la période actuelle de quiescence entre les épisodes 17 et 18. Le niveau de zoom n'étant pas identique, j'ai dû utiliser quelques repères fixes (entourés en rouge) pour superposer les deux images. Le résultat n'est pas parfait, mais à quelques pixels près c'est pas mal ! Il suffit ensuite de jouer sur la transparence des calques pour mettre en évidence le changement de morphologie de l'évent nord entre les deux images.<br>Se pose évidemment le problème de l'échelle. Je n'ai pas trouvé d'info sur le diamètre de l'évent, ce qui aurait permis de quantifier ce changement de topographie. L'idéal serait de faire ce travail en reprenant les images depuis le premier épisode, afin de suivre toute l'évolution du cône, d'estimer des taux de construction, etc. Ça ferait un bon sujet pour un escl...stagiaire de master 2 tiens...</p>

Il s'est rendu à Grindavik (très probablement après l'éruption d'août) et est accompagné par une volcanologue. Et il a eu accès à des zones en principe interdites : le gros cratère de l'éruption de mars-mai 2024, je suis pas certain qu'on puisse s'y balader pépouze.
