The Philippines is a country that can positively be taken . Chemicals. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a voilent . When lava erupts beneath a glacier or flows over snow and ice, meltwater from the ice and snow can result in far-reaching lahars. Lava can travel very far and burn, bury, or damage anything in its path, including people, houses, and trees. Lahars form when water from intense rainfall, melting snow and ice, or the sudden failure of a natural dam, mixes with this loose volcanic material, creating mudflows that can be particularly dangerous and destructive . There are many different effects after an eruption that create a health hazard for both human and wildlife alike. Most of the gas released in an eruption is water vapor (H 2 O), and relatively harmless, but volcanoes also produce carbon dioxide (CO 2 ), sulfur dioxide (SO 2 ), hydrogen sulfide (H 2 S), fluorine gas (F 2 . Climatic Effects Of Volcanic Eruptions: A landslide is a mass movement of rock fragments, soil and debris downslope. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged. Taal is the second most active volcano in the Philippines. 5. Eruptions can rapidly change productive landscapes to virtual deserts. Electrical Hazards. In addition to these immediate dangers, volcanic activity produces secondary effects such as property damage, crop loss, and perhaps changes to weather and climate. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows. Earthquake Effects We all know that the effects of an earthquake are terrible and devastating. Stratovolcano is a typical example of volcano responsible for most landslides across the globe. Using various remotely sensed images, students observe the visible effects of Mount St. Helens' 1980 eruption over time. Hazardous Materials.
