About Mount Pinatubo

Name of Volcano: Mount Pinatubo in the  Provinces of Zambales, Tarlac and Pampanga on Luzon island, Philippines
Type of Volcano: Stratovolcano
Category of Volcano: Active
Number of eruptions: Since 1600 AD, there have been at least 60 flank eruptions and countless summit eruptions; half of them occurred sincethe start of the 20th century. In, 2000, there have been four flank eruptions of Etna so far, in 2001, 2002–2003, 2004–2005, 2008-2009. Summit eruptions occurred in 2006, 2007–2008 and again in January 2012.1st known eruption ever recorded of Mount Etna is that of the Diodorus Siculus. The most destructive eruption occurred on 15h June 1991, another majour one on 20 August 1992.
Physical & Human Landscape: Fantastic lunar-like landscape, a valley of ash and volcanic rock leading to Mt Pinatubo.The caldera formed and Lake Pinatubo has since become a tourist attraction with the preferred route through Barangay Santa Juliana in Capas, Tarlac.
Danger the volcano poses:Asystem to monitor and warn of lahars has been in operation. Radio-telemetered rain gauges provide data on rainfall in lahar source regions, acoustic flow monitors on stream banks detect ground vibration as lahars pass, and manned watchpoints further confirm that lahars are rushing down Pinatubo's slopes. This system has enabled warnings to be sounded for most but not all major lahars at Pinatubo, saving hundreds of lives.
The types of things put in place to prevent loss & damage from the volcano erupting: They did resettlement for the theindigenous Aeta highlanders and the displaced lowlanders. Providing livelihood for farmers and  the closure of Clark Air Base also presented the need for short-gestating livelihood opportunities, the need to cushion the effect of massive displacement of workers, gave social services for resettlers for their final ressettlement. Institute eruption mitigation was put in to viewthe continuing threat of lahars and flashfloods.

Volcanic Hazards
What I believe should be in place to monitor the volcano: Keep an eye on the ground deformation of it often as well as the gas coming out of it.
