Climate change exacerbates the situation with typhoons in the Philippines. [7] Bagyo is the Filipino term for any tropical cyclone in the Philippine Islands. [ 4 ] From the statistics gathered by PAGASA from 1948 to 2004, around 28 storms and/or typhoons per year enter the Philippine Area of Responsibility (PAR) – the designated area assigned ...
On Luzon, the fault zone splays out into a number of different faults, including the Digdig Fault. One of the largest historical earthquake on the fault zone was the 1990 Luzon M s 7.8 event that left nearly 2,000 people dead or missing. The same part of the fault zone is thought to have ruptured in the 1645 Luzon earthquake. [7]
The wettest recorded typhoon to hit the Philippines dropped 2,210 millimeters (87 in) in Baguio from July 14 to 18, 1911. [58] The Philippines is highly exposed to climate change and is among the world's ten countries that are most vulnerable to climate change risks. [59] Building construction is undertaken with natural disasters in mind.
Much of an earthquake's total energy as measured by M w is dissipated as friction (resulting in heating of the crust). [52] An earthquake's potential to cause strong ground shaking depends on the comparatively small fraction of energy radiated as seismic waves, and is better measured on the energy magnitude scale, M e. [53]
The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. (The "M w" scale is ...
On 3 April 2024, at 07:58:11 NST (23:58:11 UTC on 2 April), a M w 7.4 earthquake struck 15 km (9.3 mi) [5] south of Hualien City, Hualien County, Taiwan. At least 18 people were killed and over 1,100 were injured in the earthquake. It is the strongest earthquake in Taiwan since the 1999 Jiji earthquake, [6] with three aftershocks above M w 6.0.
By using computer algorithms and machine learning, researchers were able to infer the following detailed picture of the Cahuilla fault zone responsible for the earthquake swarm. The fault zone is no more than 50 m (160 ft) wide, 4 km (2.5 mi) long, with the earliest seismic swarm events localized down near its base at 9 km (5.6 mi) below the ...
The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1
