1) The possible hazards that happened on the Taal Volcano eruption are:

• Ashfall
• Lava flow
• Pyroclastic flows
• Volcanic lightning
• Earthquakes
• Acid rain
• Tsunami

2) Each possible hazard in this event can be described as:

• Ashfall - a mixture of volcanic ash, rocks, and gas that can blanket the ground and contaminate water supplies. It can cause respiratory problems, damage crops, and disrupt transportation and communication systems.
• Lava flow - a slow-moving molten rock that can burn and bury everything in its path, including buildings, trees, and animals.
• Pyroclastic flows - a mixture of hot ash, gas, and rock that can travel at high speeds and temperatures, killing anything in its path.
• Volcanic lightning - lightning that is generated within the ash plume of a volcanic eruption. It can cause forest fires and disrupt communication systems.
• Earthquakes - caused by the movement of magma and the collapse of volcanic edifices. It can cause landslides, ground deformation, and damage to infrastructure.
• Acid rain - caused by the release of sulfur dioxide and other gases from the eruption. It can damage crops, buildings, and other infrastructure.
• Tsunami - caused by the displacement of water when a volcano erupts under the sea. It can cause widespread destruction and loss of life.

3) Yes, there are negative effects on this natural phenomenon to human, animals, and environment. The ashfall, lava flow, pyroclastic flows, and volcanic lightning can be deadly to humans and animals. It can also cause damage to crops, infrastructure, and disrupt transportation and communication systems. The acid rain can damage crops, buildings, and other infrastructure. The tsunami can cause widespread destruction and loss of life.

4) To mitigate the negative effects of volcanic hazards, the following measures can be taken:

• Early warning systems can be put in place to alert people of an imminent eruption.
• Evacuation plans can be developed to help people move to safe areas before an eruption occurs.
• Building codes can be implemented to ensure that buildings are built to withstand volcanic hazards.
• Agriculture and water management practices can be adapted to minimize the impact of ashfall and acid rain.
• Communication systems can be improved to help people stay informed during an eruption.
• Research can be conducted to better understand volcanic hazards and how to mitigate their impact.
