PHIVOLCS Observatory at Mount Hibok-Hibok.. The Philippine Institute of Volcanology and Seismology (PHIVOLCS, Filipino:; Filipino: Surian ng Pilipinas sa Bulkanolohiya at Sismolohiya [2]) is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily for the ...
PHIVOLCS cites seismic scale specifically developed for the Philippine setting, the different geography of each country and other "geological considerations" led to the development of PEIS. The scale measures the effect of an earthquake on a given area based on its relative effect to people, structures and objects in the surroundings.
Data Warehouse and Data Mart overview, with Data Marts shown in the top right.. A data mart is a structure/access pattern specific to data warehouse environments. The data mart is a subset of the data warehouse that focuses on a specific business line, department, subject area, or team. [1]
Eruptions were recorded from 1886 to 2006. On November 23, 2015 the volcano had a small, steam-driven explosion. PHIVOLCS raised the alert level to 1 (mild restiveness). Last eruption was on December 9, 2024 which PHIVOLCS classified as phreatic eruption. Kanlaon ejected about 3 kilometers high column of pyroclastic ash and incandescent materials.
One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. The first public version of the PL/SQL definition [2] was in 1995. It implements the ISO SQL/PSM standard. [3]
There is a gradual academic interest in the concept of data lakes. For example, Personal DataLake at Cardiff University is a new type of data lake which aims at managing big data of individual users by providing a single point of collecting, organizing, and sharing personal data. [8]
The region is bounded by subduction zones, where surrounding oceanic plates to the east and west slide towards the centre of the Philippine archipelago. [3] [2] Subduction results in deep oceanic trenches, such as the Philippine Trench and Manila Trench, which bound the eastern and western sides of the Philippine archipelago, respectively. [4]
In Metro Manila the estimated hazard has a mean PGA of 0.32 g for a PoE of 10% in 50 years. The main hazard comes from shallow fault sources, such as the Marikina Valley Fault System, but there is an important contribution to the overall hazard from the Manila subduction zone to the west and the potential for strong shaking from earthquakes ...
