Active volcanoes that can erupt at any moment: preventative and safety technologies



A volcano in Eastern Russia, previously classified as extinct, could be waking up, leading scientists to suggest a deadly eruption could occur at any time.
Scientists say the Bolshaya Udina volcano was believed to be extinct until 2017, when they started detecting increased seismic activity beneath it.
"At any moment, an eruption can occur," Ivan Koulakov, a geophysicist from Russia's A.A. Trofimuk Institute who led a study on the volcano, 

Volcanoes are as dangerous as they are majestic. Over 50 eruptions rock our planet every year. This video helps you understand what causes volcanoes to form and erupt—and shows where they are most likely to be found.
Safety Tips
• As much as possible, stay away from active volcanoes.
• If you live near an active volcano, keep goggles and a mask in an emergency kit, along with a flashlight and a working, battery-operated radio.
• Know your evacuation route. Keep gas in your car.
If a Volcano Erupts in Your Area
• Evacuate only as recommended by authorities to stay clear of lava, mud flows, and flying rocks and debris.
• Avoid river areas and low-lying regions.
• Before you leave the house, change into long-sleeved shirts and long pants and use goggles or eyeglasses, not contacts. Wear an emergency mask or hold a damp cloth over your face.
• If you are not evacuating, close windows and doors and block chimneys and other vents, to prevent ash from coming into the house.
• Be aware that ash may put excess weight on your roof and need to be swept away. Wear protection during cleanups.
• Ash can damage engines and metal parts, so avoid driving. If you must drive, stay below 35 miles (56 kilometers) an hour.

How to manage the classroom so that the learning environment is fair to all your students? In the classroom we spend all our energy and time to manage our classroom and provide them a meaningful learning environment. We focus our time on how students should be behaving and what students should be doing.
