July 2019 Cotabato Earthquake
On 9 July 2019, at 8:36 PM (PST), an earthquake measuring 5.6 jolted the province of North Cotabato, Davao del Sur, and other nearby provinces. The National Disaster Risk Reduction and Management Council reported one dead and three injured in Makilala after the earthquake, and a total of 164 families affected in Cotabato Province. Near the epicenter of the earthquake (8 km W of Makilala, Cotabato), the severity of strong ground motion was assigned VI (''Strong'') on the Modified Mercalli intensity scale. A total of 106 schools, 119 houses, and 14 other infrastructures were damaged by the earthquake. Tectonic setting The Philippine islands were formed in evolutionary processes involving subductions, collisions, and strike-slip faulting. Earthquakes are frequent there as a result of collision processes between the Philippine Sea Plate (PSP) and the Sunda Plate (SP). The slip convergence between PSP and the SP boundary is obliquely accommodated by the Philippine fault system, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotabato
Cotabato or North Cotabato ( hil, Aminhan Cotabato; ceb, Amihanang Cotabato; Maguindanaon: ''Pangutaran Kutawatu'', Jawi: ڤڠوترن كوتاواتو; fil, Hilagang Cotabato), officially the Province of Cotabato, is a landlocked province in the Philippines located in the Soccsksargen region in Mindanao. Its capital is the city of Kidapawan. Some of its barangays are under the jurisdiction of the nearby Bangsamoro Autonomous Region. History Sultanate of Maguindanao Cotabato derives its name from the Maguindanaon word ''kuta watu'' (from Malay - "Kota Batu"), meaning "stone fort", referring to the stone fort which served as the seat of Sultan Muhammad Kudarat in what is now Cotabato City (which the province derives its name from). Islam was introduced in this part of the country in the later part of the 15th century by Sharif Mohammed Kabungsuwan, an Arab-Malay Muslim warrior-missionary.

European-Mediterranean Seismological Centre
The European-Mediterranean Seismological Centre (EMSC; french: Centre Sismologique Euro-Méditerranéen, ) is an international, non-governmental and not-for-profit organisation. The European-Mediterranean region is prone to destructive earthquakes. When an earthquake occurs, a scientific organisation is needed to determine, as quickly as possible, the characteristics of the seismic event. The European-Mediterranean Seismological Centre (EMSC) receives seismological data from more than 65 national seismological agencies, mostly in the Euro-Mediterranean region. The most relevant earthquake parameters, such as the earthquake location and the earthquake magnitude, and the shaking felt by the population are available within one hour from the earthquake onset. History The European-Mediterranean Seismological Centre (EMSC) is a not-for-profit organisation with 84 member institutes from 55 different countries. The centre was established in 1975 under the request of the European Seism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismotectonics
Seismotectonics is the study of the relationship between the earthquakes, active tectonics and individual faults of a region. It seeks to understand which faults are responsible for seismic activity in an area by analysing a combination of regional tectonics, recent instrumentally recorded events, accounts of historical earthquakes and geomorphological evidence. This information can then be used to quantify the seismic hazard of an area. Methodology A seismotectonic analysis of an area often involves the integration of disparate datasets. Regional tectonics An understanding of the regional tectonics of an area is likely to be derived from published geological maps, research publications on the geological structure and seismic reflection profiles, where available, augmented by other geophysical data. In order to understand the seismic hazard of an area it is necessary not only to know where potentially active faults are, but also the orientation of the stress field. This is no ...

Active Fault
An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. * Active faulting is considered to be a geologic hazard - one related to earthquakes as a cause. Effects of movement on an active fault include strong ground motion, surface faulting, tectonic deformation, landslides and rockfalls, liquefaction, tsunamis, and seiches. Quaternary faults are those active faults that have been recognized at the surface and which have evidence of movement during the Quaternary Period. Related geological disciplines for ''active-fault'' studies include geomorphology, seismology, reflection seismology, plate tectonics, geodetics and remote sensing, risk analysis, and others. Location Active faults tend to occur in the vicinity of tectonic plate boundaries, and active fault research has foc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes ...

Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a distance equal to the rupture length away from the fault plane. The patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreshock
A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space. The designation of an earthquake as ''foreshock'', ''mainshock'' or aftershock is only possible after the full sequence of events has happened. Occurrence Foreshock activity has been detected for about 40% of all moderate to large earthquakes, and about 70% for events of M>7.0. They occur from a matter of minutes to days or even longer before the main shock; for example, the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events. Some great earthquakes (M>8.0) show no foreshock activity at all, such as the M8.6 1950 India–China earthquake. The increase in foreshock activity is difficult to quantify for individual earthquakes but becomes apparent when combining the results of many different events. From such combined observations, the increase before the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
