Environmental issues in the Philippines are not yet polluted. Species: Environmental issues in the Philippines The Philippines' evident risk to natural disasters is due to its location. Being a country that lies in the Pacific Ring of Fire, it is prone to earthquake and volcanic eruptions. In addition, the country is surrounded by large bodies of water and faces the Pacific Ocean where 60% of the world's typhoons are made. One of the most devastating typhoons that hit the Philippines in 2013 was Typhoon Haiyan, or "Yolanda", that killed over 10,000 people and destroyed over a trillion pesos worth of properties and damage to various
Lie group–Lie algebra correspondence Lie group–Lie algebra correspondence In mathematics, Lie group–Lie algebra correspondence allows one to study Lie groups, which are geometric objects, in terms of Lie algebras, which are linear objects. In this article, a Lie group refers to a real Lie group. For the complex and "p"-adic cases, see complex Lie group and "p"-adic Lie group. In this article, manifolds (in particular Lie groups) are assumed to be second countable; in particular, they have at most countably many connected components. There are various ways one can understand the construction of the Lie algebra of a Lie group "G". One approach uses
