because you will be dead
If you were on Mars having an spacesuit on would/could help you with the lack of air, but not in an earthquake. An earthquake does not remove oxygen from the air . The only reason to wear the spacesuit is to provide oxygen.
Depends on what you have. If you're wearing a spacesuit, have food/shelter.
you'd die You would die from the thin atmosphere and extreme temperatures.

Well first they would need it for oxygen saying that there isn't much if at all on Mars, they would also need one to prtect them from the deadly radiation.
If you were to go to Mars without a spacesuit, you would be exposed to the harsh conditions of the Martian environment, including extreme cold, low atmospheric pressure, lack of oxygen, and high levels of radiation. This would quickly lead to hypothermia, suffocation, and ultimately death within seconds to minutes.

without a spacesuit and an large supply of oxygen, yes you could die without those things on mars.
To live on Mars, humans would need protective clothing from the wind, and lack of air, as well as the cold. If the human wasn't inside a kind building, then the space suit would need to have a pressureized oxygen supply, and would need to either be thick enough or have a heating device to keep the human warm. It would also need to be airtight, or the oxygen would leek out. The tempertures can also get very hot on mars, so that would also need to be accounted for.
Not without spacesuits, just like the moon. If a person were to walk around Mars, they would freeze to death and die from lack of oxygen. With a spacesuit, an astronaut could walk around on Mars, just like they could walk around the surface of the moon wearing a spacesuit.
Without a spacesuit, a person on Mars would be exposed to the harsh environment which includes extremely low atmospheric pressure, lack of oxygen, and intense radiation from the sun. This would lead to rapid depressurization of the body, swelling of bodily fluids, difficulty breathing, and ultimately death within seconds to minutes.
Not without a spacesuit. And you'd have to bring your own food, water, etc. So no.
