Study Notes

Natural Disasters in Azerbaijan

Azerbaijan is located in a seismically active region and experiences frequent earthquakes.
Earthquakes can occur due to movement of the Earth's tectonic plates, volcanic eruptions, landslides, or human activities like dam construction.
The epicenter of an earthquake is the point on the Earth's surface directly above the hypocenter (focus).
The Richter scale measures the magnitude of earthquakes on a scale of 1 to 12, with higher numbers indicating greater intensity.
The magnitude of an earthquake is determined by the amount of energy released at the hypocenter.
Earthquakes can cause significant damage to buildings, infrastructure, and natural landscapes.

Earthquake Impacts

Unobtrusive (1 point): Only detectable by seismic equipment.
Very weak (2 points): Felt by those in a state of immobility.
Weak (3 points): Swinging lamps and doors, felt by a small portion of the population.
Moderate (4 points): Rattling windows, creaking doors and walls.
Fairly strong (5 points): Felt by most outdoors and all indoors, shaking buildings and furniture.
Strong (6 points): Felt by everyone, pictures fall, plaster cracks, windows break.
Very strong (7 points): Suspended objects swing, furniture shifts, cracks in stone houses, landslides on riverbanks.
Destructive (8 points): Cracks in steep slopes and moist soil, monuments budge, houses severely damaged.
Devastating (9 points): Severe damage and destruction of stone houses, bending of old wooden houses.
Destroying (10 points): Cracks in the soil, deformed roads, landslides, avalanches, tree breakage, collapsing resistant constructions, burst pipes.
Catastrophic (11 points): Wide cracks in the Earth's surface, landslides, avalanches, complete destruction of buildings, distorted railroad rails.
Strongly disastrous (12 points): Enormous changes in the soil, numerous cracks, landslides, mudslides, waterfalls, deflected rivers, total destruction of buildings, loss of plants and animals.

Earthquake Consequences

Destruction and Overthrowing of Buildings: This can lead to fatalities
Landslides and Avalanches: Can bury settlements, roads, and infrastructure, causing widespread devastation.
Tsunami: Can cause widespread flooding and destruction along coastlines.
Fires: Can be triggered by ruptured gas lines or electrical damage.
Disease outbreaks: Can occur due to disruption of sanitation and healthcare systems.
Psychological trauma: Can have long-lasting effects on survivors.

Earthquakes in Azerbaijan

Azerbaijan is located in a seismically active area, meaning earthquakes are a frequent occurrence.
Earthquakes are caused by the displacement of rock masses within the earth’s crust.
The energy released by a major earthquake is more powerful than the energy released by a megaton nuclear explosion.
The epicenter is the point on the earth's surface directly above the hypocenter (the origin of the earthquake).
The Richter scale measures the strength of an earthquake on a scale of 1 to 12.
Earthquake intensity and damage can vary depending on the focal depth, which can range from 0 to 700 km.
Earthquake damage increases with the strength of the earthquake.

Types of Earthquakes

Tectonic earthquakes are the most common and are caused by the movement of tectonic plates.
Volcanic earthquakes occur due to volcanic activity, often preceded by underground rumbles and tremors.
Landslide earthquakes are weaker tremors caused by the collapse of underground caverns or abandoned mines.
Induced earthquakes are caused by human activity such as the construction of dams or reservoirs.

Earthquake Intensity and Impacts

1-4 Points: Unobtrusive to moderate; felt mostly by individuals or those located inside buildings, with minimal damage.
5-6 Points: Fairly strong; felt by most people and can cause minor damage to buildings, including cracks in plaster and broken windows.
7-8 Points: Very strong to destructive; can cause significant damage to buildings, including collapses of older structures, and landslides.
9-10 Points: Devastating to destroying; can cause widespread destruction to buildings, roads, and infrastructure, with significant landslides and avalanches.
11-12 Points: Catastrophic to strongly disastrous; can cause extensive damage to the Earth’s surface, with widespread landslides, avalanches, and complete destruction of buildings.

Impacts of Earthquakes

Earthquakes can cause destruction of buildings, leading to deaths and injuries.
The rubble from collapsed buildings can pose an ongoing threat to safety.
Earthquakes can also cause landslides, avalanches, tsunamis, and other natural hazards.
