Sample Case Study Paper on the Pinatubo Eruption

GEOSPHERE 1: During the Pinatubo eruptions, there were massive pyroclastic flows that spread from the volcano covering up to a distance of 2-3 miles. They were made of hot masses of rocks and gasses, viscous in nature, and could move over 400 mph. This led to the destruction of the tropical vegetation as well as the displacement of the 30,000 inhabitants of the various villages on its slopes.

GEOSPHERE 2: The eruption led to an intense seismic activity, despite the absence of background information concerning seismic activity in this region. A lot of steams were released from the volcano with high energy emissions from the land surface. This eventually resulted in a flow of pyroclastic flows which deposited themselves in the valleys, filling them, alongside the large mass of volcanic ashes.

HYDROSPHERE 1: The eruptions emitted a lot of SO2 into the atmosphere. This eventually changed the overall sunset and global cooling resulting into dynamism in the climate. Its effect was most felt in the following years that the year when it eruption took place. It reduces the temperature by 1 degree for the corresponding three to four years after the event of an explosion.

HYDROSPHERE 2: Led to the release of hot springs, geysers and fumaroles that were produced by groundwater, which was heated up by the volcanic rocks. The emitted gasses led to the formation of micro acid lakes, with the formation of acidic rains from atmospheric SO2 water vapor condensation.

BIOSPHERE 1: The eruption led to the migration of aquatic animals. This was due to the formation of some thermal zones within the water. The hot water around the shore interfered with the spawning process as well as killing fishes.

BIOSPHERE 2: The seismic activities resulted in population displacement since individuals in this area were forced to relocate for the purpose of saving their lives. The vegetation covers were destroyed, leading into a complete dynamism in the composition of flora and fauna in some specific zones.

ATMOSPHERE 1: The Pinatubo eruptions occurred into the atmospheric of ash and gas cloud. The prevailing wind acted as the agent of transportation of the main ash cloud from the east-north-west. Some of these ashes fell at the sea, and the ash cloud that covered the atmosphere could be precisely tracked through the images of the GMS weather satellite. These led to the movement of volcanic cloud, which eventually resulted in the circumglobally transportation in the atmosphere.

ATMOSPHERE 2: The Pinatubo eruptions occurred in volatile emissions in the atmosphere. During this eruption processes, there were a large amount of SO2 other explosive gasses in the atmosphere. These emissions resulted in the production of large quantities of sulfate aerosol loading.
