Who discovered volcanoes?
Its volcanic activity was discovered in 1979 by Voyager 1 imaging scientist Linda Morabito.
Observations of Io by passing spacecraft (the Voyagers, Galileo, Cassini, and New Horizons) and Earth-based astronomers have revealed more than 150 active volcanoes..
Is lightning hotter than the sun?
Lightning is four times hotter than the sun. … A return stroke of lightning, that is, a bolt shooting up from the ground to a cloud (after a stream of electricity came downward from a cloud) can peak at 50,000 degrees Fahrenheit (F). The surface of the sun is around 11,000 degrees F.
What’s a dirty thunderstorm?
Dirty thunderstorms are a rare phenomenon, associated with large volcanic eruptions. … “The term ‘dirty thunderstorm’ means lightning in an eruption cloud from a volcano,” explains the German film-maker, who has been travelling to active volcanoes for almost 20 years.
Is Taal volcano dangerous?
Scientists fear a bigger “hazardous eruption” is imminent. Taal is tiny, as volcanoes go, but it has been deadly before. And according to Renato Solidum, the head of the Philippines’ Institute of Volcanology and Seismology (Philvolcs) , it is “very small but a dangerous volcano”.
What is Thund?
Thunder is the sound that accompanies lightning during a thunderstorm. … Lightning is a huge discharge of electricity, and this electricity shoots through the air, causing vibrations to be formed in two ways: 1. The electricity passes through the air and causes air particles to vibrate. The vibrations are heard as sound.
How common is volcanic lightning?
Volcanic lightning is a visually incredible, naturally occurring phenomenon that has been witnessed and documented in nearly 200 eruptions over the last 200 years.
When was the last volcanic lightning?
Vesuvius’ last eruption in 1944, but was accurately described nearly 2,000 years ago when it erupted all the way back in the year 79! The 2008 eruption of Chaiten created a large amount of volcanic lightning, but this is not a new or… [+]
What happens when lightning hits lava?
The heat and friction create a differential in electric charge that sparks a strike. The lightning zaps in and out of the thick plumes of rising ash, making the ash so hot it sometimes turns into liquid.
What is Spider lightning?
Spider lightning refers to long, horizontally traveling flashes often seen on the underside of stratiform clouds. Spider lightning is often linked to +CG flashes.
Is Taal Volcano the smallest volcano in the world?
Taal Volcano is an active complex volcano in the freshwater Taal Lake, about 50 km south of Manila. The 243-sq km Taal Lake partially covers the Taal Caldera, which was formed by the volcano’s powerful prehistoric eruptions.
How fast is a lightning bolt?
about 200,000 mphEach bolt can contain up to one billion volts of electricity. A typical cloud-to-ground lightning bolt begins when a step-like series of negative charges, called a stepped leader, races downward from the bottom of a storm cloud toward the Earth along a channel at about 200,000 mph (300,000 kph).
Is volcanic lightning rare?
Volcanic lightning is a spectacular but rare phenomenon which comes after a volcano erupts. The process has been documented for thousands of years, most notably when Mount Vesuvius erupted in the year 79.
What causes volcanic lightning?
Volcanic lightning arises from colliding, fragmenting particles of volcanic ash (and sometimes ice), which generate static electricity within the volcanic plume, leading to the name dirty thunderstorm. Moist convection and ice formation also drive the eruption plume dynamics and can trigger volcanic lightning.
How hot is lava?
The eruption temperature of Kīlauea lava is about 1,170 degrees Celsius (2,140 degrees Fahrenheit). The temperature of the lava in the tubes is about 1,250 degrees Celsius (2,200 degrees Fahrenheit).
What is the biggest volcano in Earth?
Mauna Loa’sRising gradually to more than 4 km (2.5 mi) above sea level, Hawaii’s Mauna Loa is the largest active volcano on our planet. Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa’s great mass another 8 km (5 mi).
