Yes that is the primary disadvantage of visible satellite imagery.
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.

Track its direction, and estimate its strength.
A light microscope produces an image of a specimen by passing visible light through it. This light passes through the specimen, is refracted and magnified by the lenses in the microscope, and then projected to create a magnified image that can be viewed through the eyepiece or captured using a camera.
A virtual image in optics is an image that is formed where light appears to converge, but does not physically intersect. This type of image cannot be projected onto a screen because it is perceived to be located behind the mirror or lens that produced it.
I'm sorry, but I cannot see images or satellite images. If you describe the feature labeled by "n" in the image, I can help provide information about it.
You can't. Tornadoes descend from thunderstorms, and so cannot be seen from above. You can, however, see the thunderstorms in a satellite image. See the link below for a satellite time lapse of storms tha produce tornadoes.

Photos taken of Earth from an orbiting satellite
Quite simply, a visible image is an image that is clear and perfectly able to be seen through the naked eye.
The satellite image taker?
The satellite image shows topography, natural and manmade features without political borders.
The satellite image will have more realistic surface of the Earth compared to photograph.

Visible images are only of use when taken during daylight hours because they require sunlight to make the image exposure. Infrared images relies on temperature differences to distinguish between objects and can be taken at night or daytime.
Pixels
Exposure of photographic film is an irreversible change because it permanently alters the chemical composition of the film, creating a latent image that is later developed into a visible image. Once the film is exposed, the image cannot be undone or erased.
