Landslides (El Salvador, 2001)

-Rocks and dirt slip from the mountains due to earthquakes and can bury habitat areas, killing people by asfixiation..This hazard can be avoided and prevented -Avoid building neer steep slopes, seek profesionals, use sandbags to protect your property

Continental-continetal convergent boundary of the India Plate with the Eurasian Plate (Himalaya)

• Inward convection currents.
• Lithosphere is destroyed.
• They collide
• Mountain ranges.
• Earthquakes.

Oceanic-oceanic convergent boundaries in the Aleutian Islands

- Inward convection currents.- The lithosphere is destroyed. - They collide. - Oceanic trenches and island arcs. - Earthquakes, volcanoes erruption and tsunamis.

Lahar (Mount Nevado 1985)

• Destroys everything in it's path, eruptions deposite huge amounts of ashes in rivers and maybe floods.
• Yes, they can be prevented.
• Keeping them channelized in modified natural channels or by engineering new channels.

Fires (San Francisco, USA, 1906)

-Eathquakes may affect gas stations and these might produce fires, causing many deaths. Water suply may cut out, making it more dificult to put out the fire.You can prevent and avoid this hazard. -Shut off gas valves and unplug electrical cords

Pyroclastic flow (Mount Pelee 1902)

• Burns everything on its way and leaves ashes everywhere.
• It's almost impossible to avoid it.

Continental divergent boundary in Africa

• The convection currents move outwards
• Lithosphere is created
• The plates move opposite from eatchother
• We can find rifts and oceans in the middle of continents
• Earthquakes can happen as a geological process

Lava flow (Mount Nyiragongo 2002)

• Burns everything as it advances, blocks the course of rivers and forest fires.
• No, it can't be prevented.

Continental-continetal convergent boundary of the India Plate with the Eurasian Plate (Himalaya)

• Inward convection currents.
• Lithosphere is destroyed.
• They collide
• Mountain ranges.
• Earthquakes.

Continental-oceanic convergent boundaries between Nazca plate and South American plate.

• Inward convection currents
• Lithosphere is destroyed.
• They collide.
• Mountain ranges, continental arcs and oceanic trenches.
• Volcanoes erruption, tsunamis and earthquakes.

Toxic gases released by volcanoes (Mount Laki, Iceland, 1783)

-Some of the gases released can be toxic, and play part in the formation of acid rain clouds, that can kill people if touched by the rain. You can also be intoxicated by breathing these gases. -We can prevent and avoid this this hazard. -Leave the area of the eruption, avoid outdoor activities, avoid smoking, drink fluids to prevent dehydration.

Oceanic divergent boundary in Iceland

• Convection currents move outwards
• Lithosphere is created
• Plates move opposite to eachother
• Ridges in the middle of the ocean
• Volcanoes erruptions, tsunamis and earthquakes

Transform boundary in San Andreas fault in western North America

- Transform fault.- It doesn't create nor destroy the lithosphere. - They grind past each other. - Nothing is created. - Earthquakes.

Avalanches in Nepal, 2015

Avalanches destroy everything that they touch and can cause lots of deaths of people living nearby.-This hazard can be prevented and avoided.-Avoid hiking after a storm, steep slopes, watch for cracks, did snow pits.

Tsunamis (Indonesia, 2004)

-Huge waves caused by earthquakes and can cause many floodings and deaths due to the amount of water that the waves carry.-This hazard can be prevented and avoided -Avoid inundation areas, and look for high places where the water won't reach

Explosions (Krakatoa 1883).

• The volcanic cone can be blown by pieces and it can make disappear islands.
• We can not avoid these explosions.

Ashes (Chaitén 2008)

• Can burry an entire region, destroy harvests, and damage all land-based communications.
• We can avoid the ash.
• There are many ways to avoid ashes: Limit your time outdoors and use a dust mask or cloth mask as a last resort if you must be outside; avoid areas downwind and river valleys downstream of the volcano; cover ventilation openings and seal doors and windows...
