Were gaining vantage points we couldnt get otherwise, McGonigle says. The Arenal Volcano has been one of the main attractions in Costa Rica for years. Because clouds cover the volcano for much of the year, simply catching a glimpse of the erupting peak always required a certain amount of luck. The Vulcanian eruptions produced numerous Plinian columns, some of which reached 10 km (6.2 miles) in height. Which one of these spiders is a black widow?

A model of strombolian explosions can explain the waveforms of stacked small pressure transients. Thus, Arenal appears to be rather a case of conduit fed at variable discharge rate in which persistent explosive activity could be controlled by changes in magma ascent conditions and thus also in decompression rates, as has been observed at volcanoes such as Tunguragua (Wright et al.

Iceland is experiencing quakes again and there will likely be an eruption of Fagradalsfjall volcano soon. How vulnerable are we? Plinian eruptions occurred about every 1,000 years, interspersed with lava flow and pyroclastic activity and periods of quiescence, and built Arenal into a classic stratovolcano. -- Ballistic blocks from the 1968 eruption may have traveled as fast as 400 meters per second - more than 800 miles per hour! Moreover, two components of the wavefield which follow different travel paths may produce rapidly varying interferences as described by Almendros et al. Live webcams are tracking the Fagradalsfjall volcano in Iceland, which Etna. Although lava flows have traveled beyond the base of the volcano, pyroclastic flows tend to be confined to valleys on the volcano's flanks, and have not had significant impacts on people living near the volcano since the 1968 eruption.
