Jonah Morgan – A GoPro view of surfing in Indonesia

An evening pause: Taped on August 25, 2014. Hat tip Danae, who wrote, “It was 111.4 degrees under the side porch roof this afternoon, which explains why this video appeals to me. The visibility of the sea floor is just frosting on the cake.”

To me, this probably gives one who has never surfed (like myself) the best sense of what it is like to do it.

Geologists think they have finally identified the volcano that in 1258 AD produced the largest eruption in 7,000 years — an event that was completely unnoticed by humanity at the time.

Farmers flee as Indonesia’s Mount Tambora volcano rumbles

Farmers begin fleeing as Indonesia’s Mount Tambora volcano comes back alive.

Villagers like Hasanuddin Sanusi have heard since they were young how the mountain they call home once blew apart in the largest eruption ever recorded — an 1815 event widely forgotten outside their region — killing 90,000 people and blackening skies on the other side of the globe. . . . The April 1815 eruption of Tambora left a crater 7 miles (11 kilometers) wide and half a mile (1 kilometer) deep, spewing an estimated 400 million tons of sulfuric gases into the atmosphere and leading to “the year without summer” in the U.S. and Europe.

Infrasonic detection of a near-Earth object impact over Indonesia on 8 October 2009

From a paper published on Saturday in Geophysical Research Letters, scientists describe the after the fact detection of the impact of a near-Earth object about 6 to 10 yards in diameter over Indonesia in 2009. From the abstract:

We present analysis of infrasonic signals produced by a large Earth-impacting fireball, believed to be among the most energetic instrumentally recorded during the last century that occurred on 8 October, 2009 over Indonesia. This extraordinary event, detected by 17 infrasonic stations of the global International Monitoring Network, generated stratospherically ducted infrasound returns at distances up to 17 500 km, the greatest range at which infrasound from a fireball has been detected since the 1908 Tunguska explosion. From these infrasonic records, we find the total source energy for this bolide as 8–67 kilotons of TNT equivalent explosive yield, with the favored best estimate near ∼50 kt. Global impact events of such energy are expected only once per decade and study of their impact effects can provide insight into the impactor threshold levels for ground damage and climate perturbations.

Update on Mount Merapi eruption

More on the continuing eruption of Mount Merapi in Indonesia. Key quote:

The Volcano Mitigation and Geological Disaster Agency warned of worse in store as magma pushed towards the surface from depths of 6-8km, compared with a maximum 2km deep when the mountain previously erupted in 2006. “This is the scenario I dislike the most, because the deepest magma is pushing up now,” said the agency’s chief, Surono. “The eruptions haven’t stopped, the tremors are getting stronger and one big explosion could be the result. I’ve never seen it act like this. We don’t know what to expect.”
