theguru Posted January 15, 2022 Share Posted January 15, 2022 Has anyone seen any reports on if we expected this eruption? I know scientist study volcanos and generally speaking have an idea when a volcano is heating up but I wonder if there were any recent warnings/signs about this one. Anyone?

theguru Posted January 15, 2022 Share Posted January 15, 2022 From the Great Google Machine: What are the early signs of a volcanic eruption? Notable precursors to an eruption might include: An increase in the frequency and intensity of felt earthquakes. Noticeable steaming or fumarolic activity and new or enlarged areas of hot ground. Subtle swelling of the ground surface. Small changes in heat flow. Link to comment Share on other sites More sharing options...
Voice of Reason Posted January 15, 2022 Share Posted January 15, 2022 https://www.volcanodiscovery.com/hunga-tonga-hunga-haapai-eruptions.html It looks like these Tonga volcanoes have been very active. The above link lists eruptions in 1988, 2009, 2014 and 2021. The other link I posted above talks about a gaseous plume from one of the volcanoes in December. More details about this eruption here. https://www.volcanodiscovery.com/hunga-tonga-hunga-haapai/news/170502/Hunga-Tonga-Hunga-Ha-apai-volcano-Tonga-major-eruption-sent-ash-up-to-17-km-86-000-lightnings-in-plu.html 1 Link to comment Share on other sites More sharing options...

theguru Posted January 15, 2022 Share Posted January 15, 2022 And I think this link from the same source as VoR posted gives us some recent activity: https://www.volcanodiscovery.com/hunga-tonga-hunga-haapai/news.html From that link: A new satellite image of the volcano from 2 January was captured with significant morphological changes that have formed during the latest phreatomagmatic activity. From available satellite images, it seems to confirm a new cone compared to the most previous imagery from 3 December. The new cone has likely formed by the accumulation of tephra around the vent and is located to the northeast from the previous 2014-2015 cone, already eroded by currents and waves. 1 Link to comment Share on other sites More sharing options...

I guess a tsunami gathers momentum and grows as it moves away from the force that created it? I would think with no additional power source the waves would lose energy over time. However, changes in the depth/structure should force the water up. I need someone smarter than me to tell us what is what here. Link to comment Share on other sites More sharing options...
