Arenal Volcano

Arenal, one of the world's most dynamic volcanoes, stands more than 5,000 feet high.

For the last 50% of the twentieth century, admirers flew out to its base by the thousand to get a look at shining rocks and liquid magma tumbling down its sides.

Be that as it may, Arenal wasn't continually regurgitating red-hot magma, shakes, and fiery remains.

The spring of gushing lava sat torpid for a long time, however, on July 29, 1968, Arenal got up from its sleep.

A loud quake shook the zone and an ensuing blast of magma wiped out three adjacent towns.

Visit ejections proceeded until 2010 when the well of lava re-entered a non-dynamic state.
