The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Filipino: Pangasiwaan ng Pilipinas sa Serbisyong Atmosperiko, Heopisiko at Astronomiko, [4] abbreviated as PAGASA, which means "hope" as in the Tagalog word pag-asa) is the National Meteorological and Hydrological Services (NMHS) agency of the Philippines mandated ...
The NSTA, the umbrella department for PHIVOLCS and PAGASA, became the Department of Science and Technology (DOST) in 1987. The technical staff and the 12-station earthquake monitoring network was fully integrated to PHIVOLCS in 1988. PHILVOCS and the United States Geological Survey collaborated during the 1991 eruption of Mount Pinatubo. Their ...
This was the first time PAGASA retired a typhoon name afterwards. July 9, 1964: Tropical Storm Cora (Huaning) nears Samar before dissipating. Storm warnings were issued in southeastern Luzon with Cora 100 km (60 mi) east of Samar, with forecasts projecting stormy conditions in the region and in other islands in the east-central Philippines.

[74] [87] PAGASA also retires the names of significant tropical cyclones, when they have caused at least ₱1 billion in damage and/or have caused at least 300 deaths. [92] There are no names retired within the North Indian Ocean or the South-West Indian Ocean, as names are only used once in each basin before being replaced. [90] [91]
The body concerned with standardizing the names of geochronologic units is the International Commission on Stratigraphy (ICS). In 2008 however, even though the Phanerozoic eon is almost completely divided into internationally recognizable units, local subdivisions are often still preferred over the international ones.
The final eruptions in the creation of Banks Peninsula in New Zealand occurred about 9 million years ago. A major eruption of Gran Canaria took place around 14 million years ago. Approximately 23.03 million years BP, the Neogene period and Miocene epoch begin. Cerro Guacha, Bolivia; 5.6–5.8 Ma (Guacha ignimbrite). [61]
These names, however, are not in common use outside of the Philippines. During the season, as of December 27, 39 systems so far were designated as tropical depressions by either the JMA, PAGASA, JTWC, or other National Meteorological and Hydrological Services such as the China Meteorological Administration (CMA) and the Hong Kong Observatory (HKO).
The first are the international names assigned to a tropical cyclone by the Japan Meteorological Agency (JMA) or the Joint Typhoon Warning Center (JTWC). The second set of names are local names assigned to a tropical cyclone by the Philippine Atmospheric, Geophysical and Astronomical Services Administration. This system often ends up with a ...
