After the magnitude 7.8 earthquake in New Zealand, bystanders reported flickering green and blue lights that are known as earthquake lights.
Lightning is essentially a giant spark of static electricity, though much about how and why it forms remains unknown and the subject of scientific research. It is known that lightning occurs in thunderstorms when there is a separation of electrical charge within the storm clouds, which can cause cloud-to-cloud lightning, the majority of lightning that occurs in a storm. A charge separation can also form between thunderstorm clouds and the ground, leading to classic cloud-to-ground lightning. Thunder is the acoustic shock wave that results from the heat that a lightning strike produces. NASA research suggests that lightning flashes 40 times a second around the globe.

Scientists create artificial lightning strikes to study the temperature inside real bolts of lightning.
Death by lightning strike may seem rare, but lightning has killed nearly three times as many people this year as tornadoes have, the National Weather Service reports.
Lightning has already killed as many people in the U.S. this year as in all of 2015, according to the National Weather Service (NWS).
Two passenger-planes got struck by lightning while flying over London last week, and one of the spectacular strikes was caught on video, according to news sources.
Lake Maracaibo is the spot most prone to lightning strikes on Earth, according to new data with incredibly high resolution.
Like a giant jellyfish floating through the atmosphere, red sprites hover above thunderstorms in two new photographs snapped from space by astronauts aboard the International Space Station.
For the first time, scientists have imaged thunder, shedding light on the physical processes that create it.
The sun may be partly responsible for lightning strikes on Earth, and scientists think fluctuations in the sun's magnetic field could be used to predict lightning storms weeks in advance.
Expect a 50 percent increase in lightning strikes within the United States by 2100 if temperatures continue to rise due to greenhouse gas emissions.
