The ongoing eruption at Piton de la Fournaise is continuing.

Only a crack, 100 m long is still active at present. In its upstream point, a small cone was built to 140 meters east of Rivals crater. Rhythmic projections escape from the building under construction. Further downstream, three fountains also continue to operate.

The tremor has abated since the beginning of the eruption, and the lava flow, measured at 10 m³ / sec. on 25 in the morning against 30-60 m³ / sec to 24 in the evening. On 25.08, from 6:45, no more earthquake was recorded.

Just for pleasure, the Astronomy Picture of the Day this August 25, 2015:

A meteorites rain of the Perseids (*), and the Milky Way captured above Mt Rainier, an active volcano of the Cascade Range in the United States. This image was created from a 2:00 video which recorded the fall of a dozen of meteorites, including one particularly bright during their decay in the atmosphere.

(*) The Perseids or "Tears of St. Lawrence "are a swarm of meteors (or shooting stars) visible upon entry into Earth's atmosphere; this meteorites are made of debris from the comet Swift-Tuttle, whose size ranges from that of a grain of sand and that of a small pea. Although the first traces observation date from the year 36, it was only between 1864 and 1866 it established a relationship between the meteorites and the comet whose meteorites rain comes. They are observable between July 20 and August 25.
