In the nation of Iceland there is use of geothermal energy for buiilding and space heating. Generating electricity with geothermal energy has increased significantly, Geothermal power facilities currently generate 26 + % of the country's total electricity production. Geothermal energy also provides tourist attractions such as the Blue Lagoon, Five major geothermal power plants exist in Iceland.
Living on Mars just got a lot more difficult or is this a positive. Maybe we can send Icelandics there, has it opened up the possibility of a source for geothermal power? Parts of Iceland will not freeze because during winter, pavements near these areas such as Reykjavík and Akureyri are heated up. They have a Power Station produces 303 MW the largest geothermal power installation is America's 'The Geysers' in the US, with a rated capacity of 750 MW, some of Europe has Geothermal and some Nuclear but Nuclear is getting cut back even with a reliance on Russian Oil and Gas during a War in Ukraine, Brazil has a program involving production of ethanol fuel from sugar cane, Solar is an option and PV power stations are popular in Japan, China and the United States. Countries generating more than 15 percent of their electricity from geothermal sources include El Salvador, Kenya, the Philippines, Iceland, New Zealand, and Costa Rica. 'The Geysers' is the world's largest geothermal field spanning an area of around 30 square miles.
What is Causing the Red Planet to Shake?
https://www.labroots.com/trending/space … et-shake-2
A recent study published in Nature Communications reports volcanic activity beneath the surface of Mars could be responsible for driving repetitive “marsquakes” – sudden and violent shakings of the ground, similar to earthquakes, but on the surface of Mars.
A team of scientists from Australia National University and the Chinese Academy of Sciences in Beijing have discovered 47 marsquakes that were previously undetected. These marsquakes originated beneath the Martian crust in an area of Mars called Cerberus Fossae – this is a seismically active region on Mars that is believed to be less than 20 million years old. The team speculates that magma in the mantle of Mars – the inner layer of Mars that exists between the crust and the core – is the cause of the observed marsquakes.
The researchers used data collected by a seismometer on NASA’s InSight lander, which landed on the surface of Mars in 2018. The goal of the InSight mission is to understand the evolutionary history of Mars, which would provide glimpses into the evolutionary processes of all the rocky planets in our inner Solar System. Since landing on Mars, InSight has been collecting data on marsquakes – first detected in 2020, confirming that Mars is still a seismically active planet – weather on Mars, and the interior of Mars. Mars does not have plate tectonics like our home planet Earth, and because of this it is less geologically active than Earth, thus it retains a much more complete record of its geologic history in is structure (i.e., core, mantle, and crust) than the Earth. Studying the size, thickness, density, and overall structure of Mars, and the rate at which heat escapes from the planet’s interior, can help scientists learn about the geological history of the planet.

No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.

Best wishes for success with this new topic.
You've placed this new topic in "Human Missions".
Placement in "Human Missions" allows the topic to reflect and tap into the impact of earthquakes on humans.
Your list of reactions to earthquakes by non-human living creatures is the most comprehensive I've seen.
Just FYI ... I've discovered recently that the creator of a topic can edit the topic title, by going back to edit Post #1 of the topic.
Thus, if you would like to modify the title it the topic evolves in one direction or another, you can change the topic title to match the flow.

May complicate what we can build of Mars. The idea of large adobe or rammed soil structures may need rethinking. It isn't clear if this is a strictly local phenomena or if quakes can occur globally.

Perhaps not true, but I did hear of two larger quakes attributed to the Mariner Rift Valley. Don't know if these are the same at all.
The idea that Mars is inferior in heat because of the passage of time, and it's small size may be exaggerated in my opinion. If it's interior does not churn as much as that of the Earth, then it may preserve heat better over billions of years time. So, geothermal may be fairly different.
It is possible that quakes could be associated with water ice found in the rift valley. I believe that there is thought to be a history of huge water outbursts historically on Mars. Eruptions of water, sort of.
So, both opportunity and hazards as Calliban has noted.
I believe that most people have no tolerance for the notion that there could be buried ice in the Rift Valley, in huge quantities. I myself would not have thought it possible but we have the notion that an ancient ice cap is buried very deep: https://ig.utexas.edu/2019/05/22/massiv … ea1c1b2560
Typically we think that the equator is relatively warm, but we know that the poles have wandered, and at times the atmosphere has possibly been 1/4 as thick as it is now. The point being that if deep sediments of ice and such were laid down in the rift and then buried by volcanic action and wind blown dust deposits, then some very strange icy underground actions may be possible.
Or not at all. I am open minded. I know my questions, I don't presume answers.
But Mars is an "Alien" planet. I think humans have some trouble grasping that in full.
But yes, the risk levels have risen with this information. So, that balances against settling other locations in the solar system, such as the orbits of Mars. Of course the Orbits of Mars have lots of risks as well.
Done.

Yes those deposits at the north pole are about 1 mile down, as stated.

Void, we know that the near surface of Mars has very low thermal conductivity due to the presence of dry, porous and loose regolith in near vacuum conditions. Martian dust is about as good an insulator as rock wool. It is possible that the insulation provided by the upper crust has kept the underlying layers warmer than they woukd be if Mars had a thicker atmosphere.
https://www.hou.usra.edu/meetings/lpsc2021/pdf/1237.pdf
Regarding the Mariner valley: The thin atmosphere of Mars is relatively inefficient at distributing heat. The reduced insolation at the bottom of a deep valley should directly correlate to lower average temperatures. If the ice is covered with a thin layer of regolith, it will be effectively insulated against the temperature swings that it would otherwise experience over the course of a Martian day. Temperatures may be sufficiently low for the vapour pressure of ice to be reduced far beneath local atmospheric pressure. This would allow the ice to persist for geological timescales.

I hope it will prove possible that for Mars will be more useful per geothermal than might be supposed now. But I think that it would not be a first resort, but rather something to develop along the way.

A magnitude-5 quake on Earth would be classed as moderate but causing minor damage, in space it could damage a colony with vital parts and and lead to eventual systems failure which could be fatal?

Can your dog predict an earthquake? Evidence is shaky, say researchers.
https://www.sciencedaily.com/releases/2 … 115641.htm
Source:
Seismological Society of America
Summary:
For centuries people have claimed that strange behavior by their cats, dogs and even cows can predict an imminent earthquake, but the first rigorous analysis of the phenomenon concludes that there is no strong evidence behind the claim.
Foreshocks and abnormal animal behavior strongly cluster together in the statistical analysis by Woith and colleagues, suggesting that at least some of the behaviors may be related to physical phenomena from a seismic event already underway.
"The animals may sense seismic waves -- it could P, S or surface waves -- generated by foreshocks," Woith suggested. "Another option could be secondary effects triggered by the foreshocks, like changes in groundwater or release of gases from the ground which might be sensed by the animals."
One of the biggest problems with the animal data, Woith says, is the lack of continuous, long-term observations of animals experiencing earthquakes. "Up to now, only very few time series with animal behavior exist at all, the longest being just one year."
Without a long record, Woith said, researchers cannot be sure that their observations relate to an earthquake and not some other kind of environmental change or long-term fluctuation in the health of an animal population or its predators.
How much energy is involved largely depends on the magnitude of the quake: larger quakes release much, much more energy than smaller quakes. The Richter magnitude scale was devised by Charles F. Richter in 1935 to classify local earthquakes in southern California, but has evolved into the most common parameter to describe the size of the quake and hence, its energy and potential of destructive power.
It is logarithmic, meaning that an increase of 1 corresponds to a 10-fold increase in the amplitude of the seismic waves generated, which shake the ground. It can also be used to estimate the released energy of a quake, following the Gutenberg-Richter magnitude-energy relation:
log E = 1.5×R + 4.8
or equivalently:
E = 101.5×R + 4.8
The relationship also involves that an increase of 1 in magnitude results in an approx. 30-fold increase in energy.

Cerberus Fossae are a series of semi-parallel fissures on Mars formed by faults which pulled the crust apart in the Cerberus region. They are 1235 km across and centered at 11.28 °N and 166.37 °E. Their northernmost latitude is 16.16 °N and their southernmost latitude 6.23 °N. Their easternmost and westernmost longitudes are 174.72 °E and 154.43 °E, respectively.

Earthquake waves travel more directly through the planet, while those of moonquakes tend to be very scattered; marsquakes fall somewhere in between. “Interestingly,” Kawamura continued, “all four of these larger quakes, which come from Cerberus Fossae, are ‘Earth-like.

Capturing an Avalanche on Mars
Mars Reconnaissance Orbiter (MRO) captured this avalanche plunging down a 1,640-foot-tall (500-meter-tall) cliff
Back on Earth the Japan housing must comply with the seismic standard or earthquake building codes, which have been determined by the Building Standards Law of Japan . Construction is not permitted unless the building plan does fulfill the code requirements. Japan is a seismically active country, it has high technology and has some of the most rigorous earthquake-building standards in the World. Japanese Taishin which are Quake Proof Rods and Shaking control devices, and quake-proof structure realizes reinforcement by the use of sturdy columns, beams such as dampers are installed in the structural frame, another feature of this structure is perhaps to have a machine harmonically cancel the waves, an installation of intensive devices to cancel out the shaking, allowing control of the seismic force, there is also a system to improve traditional earthquake resistance for wooden structures and a base isolation system which is considered one of the most expensive but safest, the shaking changes and people might only feel a level of 'sea-sickness' instead of the usual land quake. According to the Japanese Ministry of Land, Infrastructure, Transport and Tourism new seismic standard requires earthquake resistances that should be “almost undamaged by moderate earthquakes” and “not likely to collapse by a seismic motion that occurs once every few hundred years.
Predict an Avalanche?
https://andrewsavalanches.weebly.com/pr … nches.html
' Snow pits are the way that most researchers predict avalanches. These pits are usually on slopes that have the most avalanches. Scientists dig these square pits about 5 - 8 feet under the surface. The pits help predict if that slope will have an avalanche based on the stability of the snow layers. When the pit is dug the scientists can use a paintbrush to tell if a layer is more or less stable. If the higher layers are more brittle, the slope is more prone to an avalanche. This device is being used by almost all scientist that predict these monstrous slides. All though these pits can predict if an avalanche will happen they cannot say when they will happen. '

Giant Shake Table Helps Design Quake-Proof California Homes
https://gizmodo.com/giant-shake-table-h … 1139617755
“Earthquakes are particularly damaging to buildings with open spaces at street level because they collapse—the first-floor parking makes the building structurally weak and soft,” Colorado State University engineering professor John van de Lindt said in a press release. “There are tens of thousands of these multi-family buildings throughout California and much of the US, making this a serious safety issue.” That's why engineers are employing the world's largest shake table to design buildings that will remain standing, no matter how bad the tremor.
A lot of Earthquake deaths come down to bad building design, for example Japan or Italy or the US might have stronger flexible buildings that can take higher magnitude quakes compared to Ecuador, Indonesia, Turkey, Peru or Mexico or Iran which can have many more deaths from a lower magnitude quake. Bad planning can also lead to a disaster, exposed electric cables in Japan, gas heating, narrow streets that Firetrucks can not go down and re-claimed land that liquefied during the Kobe quake of 1995. If Mars has Quakes and Termors people on Mars will probably also have to deal with Landslides. One of the worst snow avalanches killed 310 people in the northeastern provinces of Afghanistan, Austria-Switzerland Border in the winters of 1950-1951, the Alps had “atypical weather conditions” it caused deaths of over 265 people in the area. There were food farming animal problems and Switzerland reported upwards of 500 cattle deaths from the Snow Avalanche and structures destroyed with 900 buildings destroyed. In the 1960s Tajikstan was hit by sliding rocks, dirty and mud it was reported 4,000 people were killed in this tragic natural disaster. In the 1960s in Peru 4,000 people were reported to have lost their life by snow and 10,000 9,000-10,000 total casualties from the series of slides, in WW1 an Austrian Hungarian military site was hit by a massive snow slide around 1% of the total deaths accounted for in WWI, animals also were killed, North India was hit by flood Dirt and Flood mudslides, in 2013 with 5,700 deaths in year 1999 Venezuela was hit by flowing, mud and floods and landslides, 29,000 + lives dead one the region, it was reported 10% of the population of Vargas perished in the disaster and entire towns of Carmen de Uria and Cerro Grande completely vanished under the mud bed, sometimes deaths are particularly blamed on human-made factors, poor design of river bed structure, including the construction of cheap tourism-related infrastructure in an area where the soil is not fit for development, terms "landslide" and "avalanche" and "mudslide" are often used interchangeably but they are not actually the same thing.

Three years of Marsquake measurements
https://www.marsdaily.com/reports/Three … s_999.html
The InSight mission on Mars is running out of power and most of its functions could be shut down in the months to come. Some have already been deactivated. However, the attached seismometer, SEIS, will remain in operation for as long as possible. ETH Professor Domenico Giardini takes stock of three years of marsquake measurements.
NASA's InSight lander successfully touched down on Mars on 26 November 2018. Seventy Martian days later, the seismometer - called SEIS - deployed on the surface of Mars began recording the Red Planet's tremors. It has registered more than 1,300 quakes so far. These seismic recordings have enabled the researchers to describe the interior structure of Mars more accurately than ever before.
But now the mission threatens to come to an end: the solar panels are supplying too little power because they're covered in dust. ETH Professor Domenico Giardini, who worked with a team of ETH Zurich researchers and engineers to develop the control electronics for SEIS and is responsible for the marsquake service, explains why, despite these circumstances, he's not all that pessimistic.

Can earthquakes be detected?
https://www.yahoo.com/entertainment/pre … 24379.html
Existing warning systems for earthquakes provide, at best, a few minutes of early warning and that’s only if you’re a ways away from the epicenter. If you happen to be standing over the bullseye, there is no warning for you. But there might be in the future, according to a recent study published in the journal Science.
the P-wave, or pressure wave, that arrives in advance of the S-wave?
Can animals sense an impending earthquake?
https://www.sciencefocus.com/nature/can … earthquake
There may be subtle changes prior to an earthquake that animals are able to detect.
When an earthquake strikes, different vibrations travel through the ground at different speeds. The Primary (P-wave) vibrations travel about twice as fast as the Secondary (S-wave) vibrations that do most of the actual shaking. P-waves are generally too subtle to be felt by humans, although seismographs will pick them up. But some animals may be able to detect P-waves before the S-waves arrive. This would give them less than two minutes? notice for any quake near enough to affect them.
Stories of snakes leaving their burrows, dogs barking excessively or birds flying in unusual patterns, days or weeks before an earthquake actually takes place are more contentious.

Over 100 Million Years Ago, Olympus Mons Had a Massive Landslide
https://www.universetoday.com/162902/ov … landslide/
While the surface of Mars looks relatively unchanging now, it wasn’t always so. The tallest mountain in the Solar System is Olympus Mons, a giant shield volcano on Mars that reaches 21.9 km (13.6 miles) high, 2.5 times higher than Mount Everest here on Earth. Ancient lava flows surround the volcanic caldera, evidence of an active time.
New images from ESA’s Mars Express show how these lava flows created extremely sharp cliffs, as high as 7 km (4.3 miles) in some areas, which suddenly collapsed in mind-boggling landslides. One of these landslides occurred several 100 million years ago when a chunk of the volcano broke off and spread across the surrounding plains. If we could look back in time and see as it happened, it was certainly a very dramatic and turbulent epoch on Mars.
