1A. lighting does kill people but it is very rare.. https://t.co/YaSYrSThvs
2A. when the light from the lighting is gone the air collapses back in and creates a sound wave that we hear as thunder... https://t.co/MOyoBoq8Ig #taysci4

[justin_sci @sci_justin]

2 questions
1.) Has lighting ever killed anyone?
2.) How is thunder made? #taysci4

[justin_sci @sci_justin]

2 interesting facts
1.) electrostatic potential in lower portion of ash which causes lighting to discharge into the cloud or air..
2.) Chile has 90 active volcanoes.. #taysci4

[justin_sci @sci_justin]

RT1- Active lava lake at the summit has been the source of explosive activity.. seismicity activty has increased during the second half of november 2017, sporadic ash emissions were noted during mid- and late July.. #taysci4 #stuscience

[Global Volcanism Program @SmithsonianGVP]

Report from the Bulletin of the Global Volcanism Network: Villarrica (Chile) Thermal activity increases November-December 2017 and July-August 2018; intermittent incandescence and ash

RT3- Rocks had melted after coming in contact with high voltage power lines.. locals thought that the rock was lava and had something to do with volcanic activity.. Officials made it clear that it had nothing to do with volcanic activity.. #taysci4 #stuscience

[Dr Janine Krippner @janinekrippner]

An answer: "The rocks had melted after coming in contact with a high tension power cable of the state electricity distribution company that had fallen to the ground." https://t.co/w2IncJvVZW

RT5- second anniversary of the eruption of Eyjafjallajökull that left millions stranded across Europe, and costed airlines an estimated 150 million a day for six days. eruption or 200x more powerful and are possible in Iceland #taysci4 #stuscience

[John A Stevenson @volcan01010]

The summit eruption of Eyjafjallajökull in 2010 began 9 years ago today.

Time for your annual reminder that we have had a more powerful explosive eruption since, but with much less disruption.

#taysci4 #stuscience 47 volcanoes in Latin America, 60% of active volcanoes are unmonitored. They look at 3 different types of data; sulfur dioxide gas emissions, thermal measurements, and radar data

[Alison Graettinger @AlisonGraetting]

A cool study comparing satellite observations of 47 active volcanoes in Latin America between 2000-2017 by @rsvolcguy featured in @AGU_Eos https://t.co/Tp7BBVzYQ7

[justin_sci @sci_justin]

Volcanic ash consists of very fine rock and mineral particles less than 2 mm in diameter that are ejected from a volcanic vent. #taysci4 #stuscience

[justin_sci @sci_justin]

the Bromo volcano is in east java, Indonesia. On march 26, 2019 an volcanic ash advisory was issued. Bromo sits in a plain called "sea of sand". bromos elavation is 2,329 meters high #taysci4 #stuscience

[Øystein @oysteinvolcano]

#Bromo one of Java's most active volcanoes. It last erupted in 2016, but now its erupting, again. These are some historical photos of it erupting, taken between 1890 and 1945.
