I'm going scuba-diving! I'm lucky I
already know how to dive because now I can head over to Anilao! Anilao is known
for its cool macro-life and often turtle and sharks are brought in by the
current! I'm super excited! I know I am lucky I have been offered this amazing opportunity,
but my daughter Kayla only allowed me to go if I would update a blog for her so
she can know I'm OK. And since I'm doing that, i figured I might as well keep
it educational for her! While I was on my long flight I read all the pamphlets
that sit in the back of your seat on the plane (If you ever come on this trip
you should really bring something to do!) and I learned a lot about tectonic
plates! For example I learned that the Philippines were formed by volcanoes!
Here’s a little background information on the Philippines: the Philippines
are a chain of islands in the Pacific Ocean. They are part of the continent of
Asia. This particular set of islands is on the boundary between the Pacific
plate and the Philippine plate on the southern hemisphere. These islands were
formed by a process called SUBDUCTION.
Subduction happens when one plates
starts to go over another plate, forcing the plate below down into the earth.
As the plate submerges farther below the surface is starts to get hotter and
hotter until what was once crust becomes magma and bubbles up to the surface
and becomes a volcano. The volcano then erupts repeatedly and forms a land
mass, or an island. This happens in a chain because as the tectonic plates
move, the islands move with them and a new volcano forms where the plate is
overriding the other plate. The plate that is being pulled under, forms a deep
sea trench somewhere near the volcanic islands that as it gets deeper will
eventually bubble up to form the volcano. The Philippines is a great example of
this with the Philippine plate overriding the Pacific plate. The reason there
are so many volcanoes here is because as I explained earlier, they are formed
by volcanoes.
The Philippine islands are the volcanic islands formed by this plate movement and the Mariana Trench is the deep sea trench. Subduction can happen with one continental plate and one oceanic plate or two oceanic plates.In case you are still interested, here is a map of volcanic activity, just south of where I am now. The most recent tectonic activity in the Philippines was in July of 2011 on the 25th. The magnitude was 5.9. ![](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_uAwPtjNdLBCvTRwWbspS_HH_ipRgMh-_xjTMSXZ5tN91YoPlF-pLsOSH94HtH53tSlRqa77GxbTZBtC8UZSZJboX6yfzVGybVNYkseolnJqxbWgTq9ay1pjEj4nZkbq6bjCIQtOpIJzM0yKqkyjIa-7uMuMMd6d2T1SDs=s0-d)
Naturally there are earthquakes here of a higher severity than where somewhere plates don't meet because the ground is moving, if slowly, all the time. As the tectonic plates move, the ground shakes sometimes creating major earthquakes. I hope yo learned a lot honey! I have to go, it's two, but before I post this blog I promise to attach some pictures of my dive trip. Love you!
