Why volcanic eruption and earthquake occur in the Philippines?

Why volcanic eruption and earthquake occur in the Philippines?

The Philippines sits on a unique tectonic setting ideal to volcanism and earthquake activity. It is situated at the boundaries of two tectonic plates – the Philippine Sea Plate and the Eurasian plate – both of which subduct or dive beneath the archipelago along the deep trenches along its east and west seaboard.

Why volcanic eruptions often occur in the Philippines?

There are several subduction zones of various ages colliding slowly together near the Philippines, so volcanic activity is frequent there. Because the magma under a volcano is constantly shifting, it is difficult to predict the exact details of an eruption.

Why do earthquakes and volcanic eruptions frequently occur in the same areas?

Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. First, both volcanoes and earthquakes form where one plate sinks under the other. This process, called subduction, takes place because one plate is denser than the other.

Why the eastern portion of the Philippines is more prone to earthquakes and volcanic eruption?

This is due to its location along the Ring of Fire, or typhoon belt – a large Pacific Ocean region where many of Earth’s volcanic eruptions and earthquakes occur.

What is the effects of volcanic eruption in the Philippines?

The damage extended beyond plant life. Dozens of people perished during the eruption. Large numbers of livestock and pets were also left behind when tens of thousands of people evacuated. Ash even affected the fish—mainly tilapia and milkfish—being raised in thousands of aquaculture pens in Taal Lake.

What is the effect of volcanic eruption in the Philippines?

Why do volcanic eruptions happen?

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth’s mantle melts. Another way an eruption happens is when water underneath the surface interacts with hot magma and creates steam, this can build up enough pressure to cause an explosion.

Why does the Philippines have so many earthquakes?

Why does the Philippines have so many earthquakes? The Philippines lies along the Pacific Ring of Fire, which causes the country to have frequent seismic and volcanic activity. Many earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region.

Why do earthquakes often happen near volcanic regions?

When we’re talking about earthquakes that are leading up to an eruption, the key reason they occur is magma on the move. Why do earthquakes sometimes happen in the same location as volcanoes? Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries.

Why are there so many volcanoes in the Philippines?

This relationship is Natural-Natural. This is because the areas in the Philippines that are at risk to volcanic eruptions and active volcanoes in the Philippines are two factors that are naturally occuring and are not erected by humans.

How are people affected by a volcanic eruption?

There are many pristine forests, animals, and areas of historic value that can be destroyed by volcanic eruptions. When eruptions cause destruction to cities and communities, people are forced to evacuate.
