Why People Live Near Active Volcanoes Like Kilauea. When the ground near Leilani Estates opened and began spilling out noxious fumes and lava from Mount Kilauea last week, residents of the neighborhood near the Hawaiian volcano fled. The eruption displaced many people who are living near the most active volcano on Earth, which frequently erupts along its East Rift Zone. Lava from its eruptions often flows toward the ocean, but this time it headed inland. Several hundred people have taken refuge at churches, shelters, and with other Hawaiian residents nearby as more cracks and vents in the ground opened in residential areas. This begs the question: Why live near an active volcano when you may have to leave your home at a moment’s notice, moving through air filled with ash or toxic fumes that make it hard to breathe, because of an eruption?
For starters, many people depend on volcanoes for their survival. Then there are cultural and religious reasons. “The way I kind of look at it is, the land doesn’t really belong to us. Share a link. Hawaii volcano: How many people do volcanoes kill? Media playback is unsupported on your device With its red-hot rivers of lava and clouds of ash, Hawaii's Kilauea volcano has captured the world's attention. But how dangerous are such eruptions? Every year about 60 volcanoes erupt. Some take us by surprise but others are regular offenders.
Kilauea is one of the world's most active - its present eruption began 35 years ago, but there has been an increase in activity in recent weeks. Its lava flows have quite literally been erupting in people's backyards, but thankfully only one serious injury has been reported - a man hit by projectile molten rock as he sat on his balcony. This could appear to suggest that volcanoes aren't all that dangerous, but much of the world's population lives close to an active volcano - and many of these are much deadlier than Kilauea.

Fs2011 3008. Earthquake proof buildings- where are we? - ILMM. Every year media brings us more news about seismic events. We have no control over naturally occurring earthquakes. We can, however, reduce their impact by clever engineering and constructing earthquake proof buildings. Prevention research The aftermath of an earthquake is simply devastating. But it is not the earthquake itself that results in damage. There has been an increase in earthquake engineering research in the past years. Hazard assessment is an important part of earthquake engineering. Technologies for earthquake proof buildings There are several technologies being used to construct earthquake proof buildings.
Japan engineers have used base isolation to reduce impact of ground movement on building structure. Mechanical energy of an earthquake can be transformed into heat by dampers. Commonly used technologies Earth-made building materials, such as adobe mud bricks, have been used for centuries. Another technology is seismic retrofitting. Challenges and future. Fs2011 3008.
