And in fact there are a number of USGS volcanologists at the volcano this week working on installing new monitoring equipment, so Cascades Volcano Observatory folks are on site to confirm!

Spotted yesterday at #MaunaLoa – a lava boat rides the waves! On Dec 7, a lava boat was spotted floating down channel. Lava boats can form when portions of the cone or lava channel break away & are rafted downstream. Hot lava cools to its surface to create that smooth exterior.

@jayfurr @JimGriffith_SV @DrFunkySpoon Erm...we're going to have to say no, that's not safe. (Please don't try!) If the vent is emitting a lot of SO2 or H2S, they would taste BAD. And if you add sulfuric acid (in vog, for example) to sugar, you get a pretty spectacular reaction.

#Kilauea2020 #Lava cascades from a vent in the wall of #Halema ʻumaʻu around midnight on Dec 20. The water lake has boiled away and 3 vents are generating lava flows that are contributing to a growing lava lake. Eruption is confined to Halemaʻumaʻu crater ( #K īlauea's summit).

#43YearsAgo at #MountStHelens : May 18, 1980 7 AM check with Coldwater II. “What’s it like up there, Dave?” “Very nice, totally clear” says Johnston. He's been up since 5:50 AM, making measurements, tracking the bulge. Data transmitted to Vancouver. No appreciable change in rate.

Change is a given -- especially at volcanoes. The passage of just over three weeks saw fire change to ice at the summit of Mauna Loa! As the calendar changes from 2022 to 2023, USGSVolcanoes wishes everyone a happy and healthy new year!

Map shows #MaunaLoa lava flow advance over past 36 hours. Fissure 3 remains dominant fissure, sending flows to the north, advancing at rate of 0.08 mph (130 m per hr). Lava approaching a relatively flat area & will begin to slow down, spread out. Dotted lines are fissure 4 lava.

Views from the west rim of the crater, looking generally east, at new Kīlauea eruption. Dome fountain is about 10 m (30 ft) high. Much of the east side of the crater has been covered with lava. Best webcam views are from . #KilaueaErupts @Volcanoes_NPS

A debris flow in Mount St. Helens' South Coldwater Creek at 8:45 PM on May 14 destroyed a SR 504 bridge and cut off access & power to Johnston Ridge Observatory. The event was caught on seismic data at nearby stations and may have been linked to several days of warm weather. 1/3

#Kilauea summit eruption continues. #HVO gas geochemists were able to collect SO2 emission rate data this morning. Preliminary results indicate 65,000 tonnes/day SO2, similar to the onsets of previous summit eruptions in 2020 and 2021. As downwind residents know, this means vog.

#Kilauea eruption map based on measurements at ~6:00am. Lava erupts as dome fountains (marked in orange) & feeds lava lake in #Halemaumau crater. New lava area (red) is 371 acres (150 hectares). Older islands of cooled lava (yellow) remain exposed.
