Nearly a thousand families living close to the Mayon Volcano evacuated from their homes as Philippine authorities raised its alert level of the Mayon volcano on Sunday for the second time in less than 24 hours from "increasing unrest" to "increased tendency towards eruption" within weeks or even days.

MANILA, Jan. 14 (Xinhua) -- Philippine authorities have ordered more than 900 families to evacuate as Mayon volcano continues to spew ash on Sunday.
Romina Marasigan, the spokesperson of the Philippine National Disaster Risk Reduction and Management Council (NDRRMC), said on Sunday that 919 families have been so far subjected to "mandatory evacuation" by local officials due to the "abnormal activities" of the volcano.
Marasigan could not immediately say the exact number of persons composing the 919 families evacuated but a family is usually composed of four to five members.
The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded two phreatic or steam-driven eruptions on Sunday morning. The cone-shaped volcano in Albay province rumbled back to life around 5 p.m. Saturday, spewing ash plume around 2,500 meters high.
The institute said dust fell on several villages in the surrounding towns.
Phivolcs raised the alert level around the volcano following the series of phreatic eruptions, saying the volcano continues to exhibit signs of "increasing unrest" that could trigger more ash falls, rockfalls and landslides.
"This means that the current unrest is probably of magmatic origin, which could lead to more phreatic eruptions or eventually to hazardous magmatic eruptions," the institute said.
The Phivolcs has recorded at least three "phreatic eruptions" since Saturday afternoon.
On Saturday, the institute reported that the Mayon volcano spewed ashes in the air. On Sunday morning, Phivolcs said two more steam-driven ash explosions were recorded, producing grayish steam and ash plume.
The institute warned residents around the volcano to be vigilant and do not enter the 6-km radius of the volcano due to risks of "sudden explosions, rockfall and landslides."
It also warned pilots to avoid flying close to the volcano's summit as ash from the sudden eruption can be hazardous to aircraft.
Mountain Mayon, one of the Philippines' most active volcanos famous for its beauty and near-perfect symmetry, is in Albay province on the main Luzon Island more than 300 km southeast of the Philippines capital Manila.
Phivolcs data said Mountain Mayon has an elevation of 2.46 km and a base diameter of 20 km.
The institute said it has erupted 51 times for the past 400 years. In an 1814 eruption, roughly 1,200 people were killed and three towns were buried under mud and rock. It was Mayon volcano's most destructive eruption yet.
Tourists often flock to the Albay Province to witness glowing orange and red lava flowing out of the volcano's crater.
Guidelines For Wheelchair Ramp Construction October 25, 2013 | Author: Megan Landry | Posted in Marketing
Disabled individuals are often faced with several challenges when it comes to finding easy access to many buildings. Most that are for commercial use or which are open to the public must comply with laws that require them to adhere to certain guidelines in regards to those with mobility issues. Private residence wheelchair ramp construction may use these same specifications to build safe structures.
The Americans with Disabilities Act was enacted in 1990 and has set forth construction specification that provide for the safest ramps for those with limited mobility. They cover everything from the slope progression and width to guard rails and slip protection. It even suggests the most appropriate materials for various circumstances.
Adhering to theses specifications helps ensure that the project has better quality and is safe for the people who are to use it. It needs to be made suitable not only for those in chairs but also those using crutches, canes, walkers and walking normally. Those who choose to build these structures should understand the responsibility that they are opting to take on.
Structures of this type are made from multiple types of material. Concrete is the sturdiest, most durable and unfortunately the most expensive of all the choices but should only be used for structures that are intended to be permanent. It may also be the safest because slip preventing textures may be added directly to the ramp as the substance is drying.
Steel is strong but it requires galvanization in order to prevent corrosion and rust and texture added to prevent slipping. Aluminum is strong and weather resistant but it is also slippery and expensive. It has the additional concern of being lightweight so if not properly calculated, it may bend under the weight of an occupied heavy electrical wheelchair.
The more affordable, and most commonly used material is wood but since it is a naturally occurring substance, it will need to be regularly maintained. To keep it from warping or rotting in the weather, and to keep the hand rails free of splinters, it should be thoroughly sanded and a sealant or varnish must be applied. All boards should secured using screws because nails work loose and the slats should be perfectly spaced to make for a safe ride but still allow for drainage.
ADA specifications suggest that for each foot in length, the slope rise just one inch. This angle is the right pitch to be gentle enough for someone to roll themselves up and allows one to more securely manage the decline. For the sake of safety, a level area of at least two feet should be.
