The satellite image will have more realistic surface of the Earth compared to photograph.

It is called a Thermogram, or a Thermal Image

You can go to Google Images and search true color satellite image of New York or Infrared satellite image of New York.
The satellite image shows topography, natural and manmade features without political borders.
On infrared satellite images, mountains are typically represented in shades of white or light gray. This coloration indicates cooler temperatures, as higher elevations generally have lower temperatures compared to surrounding areas. The use of infrared imagery helps in distinguishing mountainous regions from lower terrains based on their thermal characteristics.
Cloud cover, poor lighting conditions, or the angle of the satellite's view could obscure the erupting volcano from being visible in the image. Additionally, the timing of the satellite pass may not coincide with the eruption.

Photos taken of Earth from an orbiting satellite
A satellite image might fail to show an erupting volcano at night because the satellite sensors may not be able to capture detailed heat signatures in darkness. The lack of sunlight can make it difficult for the sensors to detect the thermal radiation emitted by the erupting volcano, resulting in a lesser or no visual representation of the volcanic activity.
A satellite image is a photograph taken by a satellite orbiting the Earth, capturing detailed views of the planet's surface. These images are used for various applications, including environmental monitoring, urban planning, agriculture, and disaster management. Satellite images can be captured in different wavelengths, allowing for analysis beyond what the human eye can see, such as infrared imaging for vegetation health. They provide valuable data for researchers, governments, and businesses to understand and manage natural and human-made landscapes.
Sorry, but satellite images can't show that level of detail!
The Infrared Astronomical Satellite was the first-ever space-based observatory to perform a survey of the entire sky at infrared wavelengths. It uses infrared light.
