Make a presentation about Volcano Hazards Signs of impending volcanic eruptions Prepare a plan to guide them on what to do before, during, and after a volcanic eruption.
Explore volcano hazards like lava flows and pyroclastic surges, warning signs such as quakes and swelling, and a step-by-step plan for before, during, and after eruptions to stay safe. Key: Act early!
The title slide is titled "Volcano Hazards: Signs and Preparation Plan," focusing on volcano-related risks. Its subtitle provides a guide to warnings and actions to take before, during, and after eruptions.
Guide to Risks, Warnings, and Actions Before, During, and After Eruptions
This agenda slide outlines a presentation on volcano hazards, starting with an overview of volcano hazards and signs of impending eruptions. It continues with preparation before an eruption, actions during an eruption, response after an eruption, and ends with key takeaways.

Common volcano hazards include lava flows that destroy structures, pyroclastic flows of deadly hot gas and ash, and lahars as destructive mudflows from rain or ice melt. Ashfall leads to respiratory issues and roof collapses, while gas emissions release toxic, life-threatening fumes.
Signs of impending volcanic eruptions include increased earthquake swarms, seismic activity, ground swelling, and rising gas emissions like SO2 and CO2. Other indicators are thermal changes in hot springs, as well as new fissures or rockfalls.

The slide outlines a preparation plan before a volcanic eruption, featuring key actions like assembling an evacuation kit with food, water, masks, and documents. It also covers home preparation by sealing windows and securing property, monitoring USGS alerts, and knowing primary evacuation routes.
| Action | Details |
|---|---|
| Evacuation Kit | Food, water, masks, documents |
| Home Prep | Seal windows, secure property |
| Monitoring | Follow USGS/authority alerts |
| Evacuation Routes | Know primary escape paths |

During a volcanic eruption, immediately seek shelter indoors in a central room away from windows, wear an N95 or cloth mask to avoid ash inhalation, and avoid driving due to poor visibility and road hazards. Stay indoors until an official all-clear, while protecting electronics by covering them or sealing entry points against ash.

After an eruption, clean volcanic ash carefully using wet methods like damp cloths or water sprays while wearing masks and goggles, avoiding dry sweeping to prevent airborne particles and respiratory issues. Check health for symptoms like breathing difficulties, seek medical help if needed, inspect utilities for damage, and boil or treat contaminated water before use to avoid illness.
| Clean Ash Carefully | Check Health & Utilities |
|---|---|
| Remove volcanic ash using wet methods like damp cloths or water sprays to prevent airborne particles. Wear masks and goggles. Avoid dry sweeping or using leaf blowers, which can spread fine ash and cause respiratory issues. | Monitor health for symptoms like breathing difficulties; seek medical help. Inspect utilities for damage. Avoid using contaminated water sources. Boil or treat water before consumption to prevent illness from ash pollution. |
The slide emphasizes acting early to stay safe from volcanoes by monitoring signs, preparing kits and plans, and following official guidance, noting that volcanoes are predictable. It includes a call-to-action to contact authorities for local risks.
**Act Early, Stay Safe!
🌋 Monitor signs. 🌋 Prepare kits & plans. 🌋 Follow official guidance.
Volcanoes are predictable—act decisively!
