Answer:
It is possible if 1 or both parents have the blue-eyed recessive allele
Explanation:
It works both ways.
B=Brown-Eyed Dominant Allele
b=Blue-Eyed Recessive Allele
Solution 1:
Bb x Bb
Using a Punnett Square (You can look up "Punnett Square calculator" online to find an example) you can find that there is a 25% chance for BB alleles in the offspring, 50% chance for Bb, and 25% chance for bb.
This shows it's possible for an offspring to have blue-eyes.
Solution 2:
BB x Bb
Using a Punnett Square you can find that there's a 50% chance for BB alleles in the offspring and a 50% chance for Bb.
This shows that it's possible for an offspring to have blue-eyes.

The uncertainty depends on the poor understanding of the phenomena that control the slope failures, and on the inherent complexity and chaotic nature of the landslides. One that has forcast is volcanic eruptions.

If a dormant volcano starts to release gases and small earthquakes are recorded, what could this mean?
Answer: It means that its showing some volcanic activity that could lead into an eruption.
Explanation: Dormant volcanoes can show activity/signs that is could erupt. Gases, small earthquakes, loud explosions are signs of an eruption is going to occur. If a dormant volcano hasn't showed any activity for 2,000 years, its considered to be dead or extinct.
It indicates that there is some volcanic activity, which could lead to an eruption.
What is dormant volcano?Dormant volcanoes are those that have not erupted in a long time but are expected to do so in the future. Mount Kilimanjaro in Tanzania, Africa, and Mount Fuji in Japan are examples of dormant volcanoes.
Volcanoes become dormant when magma from the Earth's mantle can no longer reach them. Mount Rainier and Mount Fuji are examples of dormant volcanoes that are "sleeping" but may awaken in the future.
Dormant volcanoes can exhibit activity/signs that they are about to erupt. Gases, small earthquakes, and loud explosions are all indicators that an eruption is about to occur.
If a dormant volcano hasn't erupted in 2,000 years, it's considered dead or extinct.
Thus, this way, it indicates that it could lead to eruption.
