Bakit hinde katulad ng sa new Zealand or Hawaii na mga volcanoes dito pag pumutok yun Meron na lumalabas na lava? Iba ba mga volcanoes natin?

Mechanism of formation is different. hawaiian volcanoes are "hot spot" volcanoes. Source of magma is almost similar to mantle material or what is called "primitive". Not much water (not so explosive eruptions), hotter, low in silica and high in iron and magnesium (black and smoother lava), hence flows much easier. In contrast Philippine and New Zealand volcanoes are island arc type. Magma comes from partially-melted material under the crust caused by mixing of water. The water acts as a "flux", makes the melting point of the rocks lower. The water come from oceanic crust diving under another crust. The water makes our volcanoes more explosive, and because the magma comes form recycled rocks, its less-"primitive" and therefore has higher silica, lower tempearture and slightly lower iron and magnesium content (lava is lighter in color and more blocky).
Oh, Mr. President.

Same as last year, violent, but I don't expect it to be of the same magnitude (I can still be wrong). Its giving off lots of gas and steam w/c means its not building up much pressure and its only been the last eruption. Compare yung video last Friday vs video nung 2020. Maiksi lang and maliit yung Friday.
Mga bulkan sa Japan, Pilipinas, Indonesia, Italy, New Zealand & South America are pretty violent when they erupt. Lots of explosions. Hawaii, East Africa and Iceland naman less violent to even quiet but can still be spectacular.
i am...
disheartened.
we used to be the english masters in this part of the planet.
