T O D A Y ' S T O P I C I N T R O D U C T I O N We’re about to find out what do to Before, During and After a Volcanic Eruption. In addition, We’ll also learn about the types of volcanoes, eruption and parts of volcanoes. Let us start now.

P A R T S O F V O L C A N O Feel free to make this an open discussion for questions or clarifications before proceeding.

W H A T T O D O? B E F O R E , D U R I N G A N D A F T E R In the following slides, we’ll be informed what to do Before, During and After a Volcanic Eruption.

1. Evacuate immediately if you live or are staying within the radius of affected areas. Long before the explosion, affected areas would have been given a warning to evacuate the premises by local government units.
2. Stay tuned to national news and your local community’s channels to be on top of the situation and stay informed with local safety plans and evacuation areas. Whether it’s through local radio, TV news, or official social channels of news outlets, make sure that you’re getting reliable information from trusted sources and not potentially dangerous misinformation from hoax accounts.
3. Charge your electronics. Keep your mobile devices and power banks charged in case of power interruptions.
4. Know disaster hotlines and other emergency hotlines. Save these numbers in your mobile phone:

• National Emergency Hotline: 911
• PHVOLCs – (02) 8426-1468 to 79
• Philippine Red Cross – 143 or (02) 8790-
• Bereau of Fire Protection – (02) 8426-
• National Disaster Risk Reduction And Management Council (NDRRMC) – (02) 8911-5061 to 65 local 100 Here’s a complete list of government hotlines: https://www.gov.ph/hotlines

5. Prepare a go-bag in case of evacuation. This should include:

• A mask per person (N95 or makeshift)
• Copies of personal documents
• Phone and powerbank
• Flashlights and batteries or candles and matches
• 3 gallons of potable water per person
• 3 days worth of non-perishable food
• Hygiene and sanitation items •First aid kit and maintenance medication
• Extra cash BEFORE A VOLCANIC ERUPTION

1. Do not leave your home or indoor shelters until notified by the local government that it is safe to do so. Evacuate to safer grounds only when notified.
2. Keep a watchful eye on your kids or loved ones who may be tempted to go out to see what’s going on outside.
3. Wear protection. Use masks, glasses/goggles, long sleeves, pants, and shoes when clearing out ash to protect your lungs, skin and eyes.
4. Clean your gutters and roof with water after clearing out the ash to prevent corrosion.
5. Wait for further announcements from LGUs or national news related to the volcanic eruption. AFTER A VOLCANIC ERUPTION

Strombolian and Hawaiian Eruptions These are the least violent types of explosive eruptions. Hawaiian eruptions have fire fountains and lava flows, whereas Strombolian eruptions have explosions causing a shower of lava fragments. Vulcanian Eruptions Vulcanian eruptions are small to moderate explosive eruptions, lasting seconds to minutes. Ash columns can be up to 20 km in height, and lava blocks and bombs may be ejected from the vent. V O L A N I C E R U P T I O N 5 D I F F E R E N T T Y P E S O F V O L C A N I C E R U P T I O N S Subplinian and Plinian Eruptions Eruptions with a high rate of magma discharge, sustained for minutes to hours. They form a tall, convective eruption column of a mixture of gas and rock particles, and can cause wide dispersion of ash.
