Volcano plots represent a useful way to visualise the results of differential expression analyses. Here, we present a highly-configurable function that produces publication-ready volcano plots. EnhancedVolcano will attempt to fit as many point labels in the plot window as possible, thus avoiding 'clogging' up the plot with labels that could not otherwise have been read. Other functionality allows the user to identify up to 4 different types of attributes in the same plot space via colour, shape, size, and shade parameter configurations.
Hello. I have made myself a simple gold volcano setup that doesn't require much (although is much easier with a slush geyser, but aquatuners could work). I don't have any of the steam turbines and stuff like that, because it seems too complicated (yes I know in QoL M3, steam turbines will be extremely useful). All it needs is some cool water (under 20C is fine), obsidian, igneous cock, and a little bit of wolframite. Here is the setup:
So, as you can see, you have to insulate the area around it, then have a little pool of the cool water. If using PW, it is important to make sure that the pool is full at all times, to prevent PO2 from forming and messing everything up. Also, it is very important to make the metal tile out of tungsten. If you use another material such as gold (which I did the first time), the metal tile will melt and the gold will fall into the volcano, which will create a lot of steam, which would mess up the vacuum. I realize that there are better ways to do this, and that the liquid gold to solid gold ratio is pretty bad, but I have found this setup to be 100% working. I have left the liquid pump's output open because I have not needed to use the pump at the moment. Also, the thermo-sensor is set to > 10C (although I'm sure that you could set it to up to >30, but cooling would be really slow).
That's the setup i'm using for my gold volcano. It's not super complicated like I have seen all over, but if anybody has any improvements that could be made to the setup, I would greatly appreciate it.
My big thought here is maybe this hybrid approach is actually wrong and you should just directly have the metal volcano be part of the steam room, so that the steam cools down the liquid metal to make it sweepable to put on rails for final heat offloading and then cooling, with no petroleum involved. It might be a bit tricky, but would condense things down as long as the steam below the overpressure limit is still sufficient to take the heat.
A single-chamber system doesn't have any advantages thermally. The heat exchanger in this system keeps the petroleum pool in the volcano room the same temperature as the steam in the steam chamber. The main thing you'd gain is you could build it without petroleum, but you'd have the drawback that the chamber would always be full of high-pressure steam, which would make servicing it with Dupes very difficult.
Spacesuits can handle the steam, of course, but you'd need an airlock that could handle high pressure steam. Waterlocks can't do that. An oil or petroleum lock could, but the point of going with high-pressure steam is to build it before you have access to those. A pump airlock like the one I typically use can't send the steam back into the volcano / steam chamber, because the pressure's going to be above 20 kg/tile.
Now, in theory a single-chamber system shouldn't require Dupe service. I generally completely seal my turbine steam chambers and don't attempt to service them once built. However, I only get away with that because I've built enough of them that I rarely make mistakes. I had to send Dupes into the volcano chamber of this one several times because I'd made various errors and I had to correct them.
I used to build even bigger metal tile heat exchangers, but that was when I was brute-force cooling the copper from 2226 C. In actual operation, with this system the copper is always at the steam temperature by the time it leaves the steam chamber, which is 125 C - 200 C depending on where it is in the volcano cycle, and it's always at 15 C or below long before it leaves the metal block. No testing of the rail temperature required.
This is pretty much the design. All the heat is leaking out that hydrogen on the right that I need to suck back out. I had the temp sensor in way too much steam before and it took too long to change temps for the sensor. Otherwise it doesn't need any timers. This is just a gold volcano but his example worked just fine off an iron. There would be an aquatuner in the steam room but I have one in a room below the screen shot that I used for cooling.
At most U.S. volcanoes, observatories traditionally have employed a two-component approach to volcano monitoring: (1) install instrumentation sufficient to detect unrest at volcanic systems likely to erupt in the not-too-distant future; and (2) once unrest is detected, install any instrumentation needed for eruption prediction and monitoring. This reactive approach is problematic, however, for two reasons.
1. At many volcanoes, rapid installation of new ground-1. based instruments is difficult or impossible. Factors that complicate rapid response include (a) eruptions that are preceded by short (hours to days) precursory sequences of geophysical and (or) geochemical activity, as occurred at Mount Redoubt (Alaska) in 1989 (24 hours), Anatahan (Mariana Islands) in 2003 (6 hours), and Mount St. Helens (Washington) in 1980 and 2004 (7 and 8 days, respectively); (b) inclement weather conditions, which may prohibit installation of new equipment for days, weeks, or even months, particularly at midlatitude or high-latitude volcanoes; (c) safety factors during unrest, which can limit where new instrumentation can safely be installed (particularly at near-vent sites that can be critical for precursor detection and eruption forecasting); and (d) the remoteness of many U.S. volcanoes (particularly those in the Aleutians and the Marianas Islands), where access is difficult or impossible most of the year. Given these difficulties, it is reasonable to anticipate that ground-based monitoring of eruptions at U.S. volcanoes will likely be performed primarily with instruments installed before unrest begins.
I am trying to install the software 'EnhancedVolcano' to make volcano plots in R, however it says that EnhancedVolcano is not available for R version 3.2. Does anyone have experience with installing EnhancedVolcano? If yes, which version of R were you using.

Mount Edgecumbe volcano in Southeast Alaska has become the latest addition to the Alaska Volcano Observatory's ground-based monitoring network. An observatory team in early September installed three seismic and Global Navigation Satellite System stations on the reawakened volcano and upgraded the only existing station in the vicinity, a temporary one on nearby Crater Ridge.
"The initial part was the detection of unrest in April of last year and then trying to understand the cause of unrest, which we linked to the inflation of the volcano," he said. "Then we worked with the community of Sitka to inform them about our understanding of the volcano and its current activity and to cooperate with them on permitting for a ground-based monitoring network."
The volcano's three new seismic and GNSS stations have been placed around the flanks of the volcano at roughly the 4, 7 and 10 o'clock positions of an analog clock. The lone station on adjacent Crater Ridge has been upgraded to replace a temporary GPS antenna mast with a reinforced steel tripod.
"When you go to a place and start recording data, you don't know whether it shows an anomaly or whether this is the normal state of the volcano," Grapenthin said. "So we start by getting a feel for how the volcano works."
Mount Edgecumbe will be assigned a color code when scientists have a fuller understanding of the volcano. The observatory uses green, yellow, orange and red to denote a volcano's status. Green denotes typical background activity, and red warns that an eruption is underway or imminent.
The lone seismic station on Crater Ridge helped AVO detect smaller earthquakes but didn't substantially increase AVO's ability to locate those events using the regional seismic network. The absence of that information meant less was known about the volcano's activity.
The W.M. Keck Observatory has been in operation for nearly 30 years atop Maunakea, a dormant volcano and the highest point in Hawaii. The twin telescopes are arguably the best place to go for astronomical observation in the Northern Hemisphere. At an elevation of 13,796 ft, stormfronts regularly pass below the observatory, and the skies above the Pacific Ocean are clear of light pollution.
Foundations turned out to be a major design element for the array. The roof surface between the Keck I and II telescopes is EPDM covered by cinder from the dormant volcano. Removing the rock by hand for the initial design took days, Devenot said. Installers brought a mini-excavator to Maunakea to carefully remove the cinder.
The installation crew was housed at the Onizuka Center for International Astronomy on the mountain to acclimate to the climate, and installers were provided with emergency oxygen kits. The environment might be ideal for solar panels, but installers had to be cautious of UV exposure, low humidity and derated winds that could reach hurricane speeds.
