Geological evidence shows that, since the year 1200, new eruptions have occurred mostly from vents/fissures along rift zones. Prior to that, lava erupted mostly from the summit before sometimes overflowing the summit crater.

FWIW: official USGS volcano information will always come from accounts that have the handles @USGSVolcanoes, @alaska_avo, & @USGS and are linked from our web pages.
Visit usgs.gov/programs/VHP/connec… for info.

This short video shows thermal camera footage of the onset of the #MaunaLoa eruption from the volcano's summit. The temperature in degrees C is shown by the colored scale bar on the right. For additional information visit: usgs.gov/volcanoes/mauna-loa… #MaunaLoaErupts

#MaunaLoa is erupting from vents on the Northeast Rift zone. Flows are moving downslope to the north. USGS Photos from Civil Air Patrol fight. #MaunaLoaErupts @Volcanoes_NPS @Hawaii_EMA @CivilDefenseHI

What I find amazing about this is that these oceanic volcanoes have been building up huge mountains under the water for an incredibly long time, and we get to witness the moment they reach the surface.
This can also happen multiple times as the ocean erodes away a young island.
Volcanoes are the demonstration that #Earth is a #LivingPlanet

Hi everyone! I am a 2nd-year Geology MSc student studying the petrogenesis of newly recognized volcanoes in Alaska. I am looking for Ph.D. opportunities within the realm of volcanology, igneous petrology, and geochemistry at subduction zones. You can find my CV with this QR code.

Hi Twitterverse, very informative video for questions related to #Taupō. Follow @geonet for any updates and watch out for imminent misinformation. Be very wary of what you read, anything with the term 'caldera' or 'supervolcano' gets ridiculous misleading hype attached to it.
Following the rise in Volcanic Alert Level at Taupō Volcano today, we have a video update from @gnsscience Volcanology Team Leader Nico Fournier who explains this change and the current volcanic activity at Taupō: youtu.be/AbXQeA0zSfI

You can see our Taupo volcano factsheet from this link, which is looking fabulously shiny and new thanks to a big team effort:

How inclusive do you think volcanology is? In our new preprint, we tried one way of looking at it. We investigated how often locally affiliated authors are included in or lead research about volcanoes in their own countries. #volcano #inclusion

ALT Stacked horizontal bar graph showing how often locally affiliated authors are A. lead authors of research and B. included in research about volcanoes in their country. X-axis is percentage of articles including a local author, y-axis is countries with at least 50 articles published about volcanoes located there.

Steady decline in activity at Fagradalsfjall continued today. Lava pond within the vent is lower and split into 2 sources. No visible outflow from the vent and yesterday’s outflow channel is drained. – at Iceland

Not only do we now have the first chemical analyses, we have the first microscope picture too! Here you can see lots of bubbles (vesicles) formed by volcanic gases, alongside crystals (plagioclase, clinopyroxene, and olivine) that grew while the magma was underground.

⚠️📣DO NOT WALK ON THE LAVA! Old or New
Here is one very good reason why: (1/7)
