Hazard maps are used to simulate the areas that are likely to be affected during any catastrophe, including volcanic eruptions.
True
False
According to the hazard map of Taal Volcano during its unrest in early 2020, communities within the 14 kilometer radius from the volcano’s main crater need to be totally evacuated.
False
True
According to the hazard map of Taal Volcano during its unrest in early 2020, communities within the 17km to 20km radius from the volcano’s main crater need to be totally evacuated.
True
False
Hazard maps provide accurate and precise information on the risks of hazards during volcanic eruptions.
False
True
The risk of hazards decreases the further away from the center of the volcano.
False
True
What to do Before a volcanic eruption
Stay informed: Stay updated with the latest information from local authorities, such as volcanologists, emergency management agencies, and government officials. Follow their instructions and advice.
Have an emergency kit: Prepare an emergency kit that includes essential supplies like food, water, first aid kit, flashlight, batteries, dust masks, and a battery-powered radio. Keep the kit in an easily accessible location.
Pillage and Plunder: Since everyone is out of their homes because of evacuating it is a good time to take what's theirs and blame it on the volcano
Just give up
Nothing matters
We are all gonna die anyway
what to do During a volcanic eruption:
Protect yourself from ashfall: Stay indoors, close all windows and doors, and seal gaps to prevent ash from entering your home. Use dust masks or damp cloths to cover your nose and mouth if you must go outside.
Record a video: Get your phone and start recording to post it in social media for likes
Avoid volcanic gases: Volcanic gases, such as sulfur dioxide, can be toxic. If you are near the eruption site, use a mask or cloth to cover your nose and mouth, and avoid areas with heavy gas concentrations.
Eat health foods: Research shows that a person who is physically healthy are resistant to ashfall to a certain degree
What to do After a volcanic eruption:
Wait for official clearance: Do not return to evacuated areas until local authorities have declared it safe to do so. Be patient and wait for official clearance before returning home.
Be prepared for aftershocks: Volcanic eruptions can trigger earthquakes, so be prepared for potential aftershocks and follow earthquake safety guidelines.
Seek medical attention if needed: If you experience respiratory or other health issues due to volcanic ash or gases, seek medical attention promptly.
Prepare for homelessness, it may be unlikely that your house got affected but there is still a chance.
What not to do during a Volcanic Eruption
Follow official instructions: Stay tuned to local authorities for updates and follow their instructions. If instructed to evacuate, do so immediately and follow the designated evacuation routes.
Avoid low-lying areas: Stay away from low-lying areas that could be prone to mudflows (lahars) or flooding caused by melting snow and ice from the volcano.
Go outside:
Try to get signal or connection to contact your love ones to check if they are safe
Panic and run around screaming
