Volcanic Hazards

1.

1. Eruption Column The vertical pillar of tephra and gases rising directly above a vent. Mt. Pinatubo, Mt. Karymsky in Russia

Volume of Ejected Debris Ash

2.

2. Debris Avalanche (Landslide) Gravitational force “pulls” unstable material down slope Fills canyons and valleys with debris

Landslides Monserat, Lesser Antilles, Las Colimas, El Salvador

3.

3. Pyroclastic Flow Contain a high-density mix of hot lava blocks, pumice, ash and volcanic gas. Destroys everything in its path. Mt. Pinatubo, Philippines, 1991 Fuego volcano in Guatemala May reach 100 miles per hour

4.

4. Fumaroles Vents from which volcanic gas escapes into the atmosphere. Fumaroles may occur along tiny cracks or long fissures. Fumarole on Kīlauea Volcano, Hawaiʻi. Elemental sulfur vapor escaping from the fumarole has cooled to form yellow-colored crystals around its margins.

5.

5. Lava Bomb Ejected magma that solidifies in mid-air and falls back to Earth as solid rock.

6.

6. Lava Dome Formed by viscous magma being erupted effusively onto the surface and then piling up around the vent.

7.

7. Lava Dome Collapse When the lava dome is too steep & it collapses due to gravitational force. Sinabung, Sumatra Monserrat

8.

8. Lahars (Mud or debris flow) Hot or cold mixture of water and rock fragments that flows down the slopes of a volcano. Need water source

9.

9. Acid Rain Rainfall containing elevated levels of strong acids, due to carbon emissions. Iceland

10.

10. Tephra (Ash) fall Fragments of microscopic rock ejected into the air by an erupting volcano. Clogs machinery, covers vegetation, irritates lungs and eyes Photomicrograph of ash from the Mt. Tehama eruption (Lassen Peak) Ash deposited associated with the eruption of the Long Valley Caldera

11.

11. Eruption Cloud A cloud of tephra and gases that forms downwind of an erupting volcano. Can drift for 1000s of kilometers Guagua Pichincha, Ecuador. Eruption cloud from Guagua Pichincha Volcano 10 km west of Quito,

Understanding Volcanic Hazards Past history How often Types of hazards Extent of hazards Location of past events Ash deposits associated with the eruption of Santorini, Greece
