Foreshocks may occur days, or even years, before the actual major earthquake itself.
Foreshocks are detected in almost half of all moderate to large earthquakes, and they are detected in over 70% of earthquakes that are above 7.0 in magnitude on the Richter scale. Foreshocks then lead to the main shock, which may be followed by after shocks, depending on the strength of the main shock.
Answer:
1. Sympathetic
2. Parasympathetic
Explanation:
The sympathetic nervous system is activated when the person experiences any stress conditions. This nervous system stimulates the release of stress hormones from the adrenal gland and generates flight or fight response. There are an increased heart rate and breathing rate to increase the oxygen supply to skeletal muscles.
Once the person comes out of the stress conditions, the parasympathetic nervous system is activated which slows down the physiological responses generated by the sympathetic system. The activated parasympathetic nervous system stimulates the digestion and absorption of nutrients.
