The volcanic unrest continues around the world.

Eruption of Agung volcano on July 4, 2018

On July 4, 2018 at 12:20, a plume of ash and gas rose 2,500 meters above the summit. The new eruption lasted about 2 minutes and had an amplitude of 24 mm on the seismogram. In this awesome timelapse recorded at 7 am in Amlapura and from 11:15 – 15:36 in Datah, Karangasem, you can watch the ruptions at 1’24 and 1’50:

Satellite images indicate ongoing effusive activity and a dome growing by 4 to 5 million m³ last week. The flux of magmatic sulfur dioxide remains high, with 1,400 – 2,400 tonnes / day on 3 July, and 400 – 1,500 tonnes / day on 4 July.

Strombolian eruptions at Anak Krakatau, Indonesia

Anak Krakatau is exploding frequently since June 18, 2018. The last strombolian eruptions are however becoming stronger and more frequent – almost every 20 minutes – with lava bombs being ejected more than 1km away from the crater!

The lastest eruption occurred on July 3, 2018 at 5:33am, which lasted 40 seconds and had an amplitude of 38mm on the seismograph.

Mayon volcanic eruption on July 1, 2018 in the Philippines

Mayon volcano erupted on July 1, 2018, at 12:30, sending blue and white clouds of ash 500 meters above the crater.

Fuego volcano Update

More than three hundred people are still missing 1 month after a massive eruption occurred at Fuego in Guatemala. The eruption has now became the most powerful in recent years, affecting more than 1.5 million people.

Unrest at White Island in New Zealand

This lake is filling at a rate of 2,000 m³ per day … same rate as in 2003-2004, 2007-2008 and 2013, when previous lakes have drowned, leading to localized geysers and small geothermal eruptions, with occasional formation of small cones of tuff-debris around the vents. If the current lake filling continues at this rate, dome drowning is expected in 3-4 months.

Volcanic Alert Level 1 and aviation color code remains green.

Kilauea eruption update

In the East rift zone of Kilauea, the activity of crack 8 continues. The lava flow underwent temporary blockages on July 3 and 4, which caused overflows near the Kapoho cone. These overflows have destroyed some more houses.

The National Weather Service reports a rare storm over the active lava field of the rift zone on July 2, that produced 1,200 lightnings in just 7 hours. Kilauea lava is fueling thunderstorms

The NWS meteorologist says that the volcano played a major role in this stormy episode, being the basis of the emission of Pyro cumulus. The other actor was an air pocket colder than normal at a lower altitude.
