Corazón (Claudia Leitte song)

"Corazón" is a song recorded by Brazilian singer Claudia Leitte featuring Daddy Yankee. The track was written by Antonio Rayo Gibo, Beatriz Luengo, Yotuel Romero, Raymond Ayala and Derrus Rachel. "Corazón" is a Latin-pop and reggaeton, backed by clicking percussion, the song was released on December 17, 2015 on TIDAL and iTunes. "Corazón" won the award for Best Latin Collaboration of the Year at the 2016 Latin Music Italian Awards and won a 2017 Billboard poll for Best Portuguese/Spanish collaboration. Leitte went to New York in December 2013 where Jay Brown presented her the song, though she took two years to release it due to being hesitant at first about recording in Spanish. After making some adjustments in production and adding more Brazilian elements to the final mix, she decided to use the track. Leitte and Yankee gave their first televised rendition of "Corazón" on The Voice Brasil, on December 19, 2015; the video was shot in Praia Vermelha, in the city of Rio de Janeiro, between 15 and 16 December 2015.

Shooting took between 23 hours. The renowned designer Giovanni Frasson was responsible for all of Leitte's costumes in the video. During an interview on Baiana FM on January 8, 2016, Leitte gave some details from the video, defining it as the sexiest of her career. Leitte announced on Twitter that the music video would be released on January 28. In addition to the announcement, she released two shots from the video. On January 27, Leitte's website begun a countdown to the launch for the video launch. A making-of of it was released that same day on social media; the website Glamurama released an exclusive video clip of a Leitte photoshoot by Rachel Tanugi Ribas, announced that the music video was directed by Marcos Mello, a Brazilian pioneer director in fashion film

Puʻu ʻŌʻō

Puʻu ʻŌʻō is a volcanic cone in the eastern rift zone of the Kīlauea volcano of the Hawaiian Islands. Until the end of April 2018, Puʻu ʻŌʻō had been erupting nearly continuously since January 3, 1983, making it the longest-lived rift-zone eruption of the last two centuries. By January 2005, 2.7 cubic kilometers of magma covered an area of more than 117 square kilometers and added 230 acres of land to the southeast coast of Hawaiʻi. The eruption claimed at least 189 buildings and 14 kilometers of highways, as well as a church, a store, the Wahaʻula Visitor Center, many ancient Hawaiian sites, including the Wahaʻula heiau; the coastal highway has been closed since 1987, as parts of the road have been buried under lava up to 35 meters thick. The hill was nicknamed "Puʻu O" by volcanologists, as its position when marked on a map of the area coincided with an "o" in "Lava flow of 1965"; the elders of the village of Kalapana were asked to name the new hill, chose Puʻu ʻŌʻō, meaning hill of the digging stick.

The name is often translated as "Hill of the ʻŌʻō Bird". The Puʻu ʻŌʻō eruption began when fissures split the ground in the remote rainforest of the eastern rift zone, on January 3, 1983. By June 1983, the activity had localized to the Puʻu ʻŌʻō vent. Over the next three years, 44 eruptive episodes with lava fountains as high as 460 meters stopped traffic at points across east Hawaiʻi; the fallout of cinder and spatter from the towering lava fountains built a cone 255 meters high. In July 1986, the conduit feeding magma to Puʻu ʻŌʻō ruptured, the eruption abruptly shifted 3 kilometers downrift to form the Kūpaʻianahā vent. With the new vent came a new style of eruption: continuous, quiet effusion from a lava lake replaced the episodic high fountaining. After a few weeks, a roof formed over the main lava outflow channel; the lava tube allowed the fluid pahoehoe lava to flow long distances. In less than a year, overflow from the lake created a broad and low shield about 55 meters above Kūpaʻianahā.

Lava streams were first visible from the town of Kapaʻau in November, 1986. In the course of that month, lava cut a swath through Kapaʻahu, covered the coastal highway, reached the ocean 12 kilometers from the vent; some weeks the lava flow shifted eastwards and buried 14 houses in the town of Kalapana within one day. The lava flow at Kalapana ceased. In 1990, the eruption entered its most destructive phase, when flows turned eastward and destroyed the villages of Kalapana and Kaimū. Kaimū Bay and Kalapana Black Sand Beach were completely covered with lava. Over 100 homes were destroyed by the ever-broadening flow field in a nine-month period. New tubes diverted lava away from Kalapana early in 1991, lava once again entered the ocean within Hawaii Volcanoes National Park; the volume of lava erupted from Kūpaʻianahā declined through 1991, in early 1992, the vent died. The eruption returned to Puʻu ʻŌʻō, where flank vents on the west and southwest sides of the cone constructed a new lava shield. Soon lava tubes were feeding lava from the vents with few surface flows in between.

The flank vents have held center stage since, with the exception of a two-month pause in activity, early in 1997, which followed a brief fissure eruption in Nāpau Crater, a short distance southwest of Puʻu ʻŌʻō. On the evening of January 29, 1997, a series of earthquakes struck Kīlauea's east rift zone. Deep within the rift zone, magma was escaping from the conduit leading to the Puʻu ʻŌʻō vent, cutting off the supply to the ongoing eruption; the lava pond at Puʻu ʻŌʻō drained, residents 10 miles away heard a low, rumbling roar as the crater floor dropped 500 feet and the west wall of the Puʻu ʻŌʻō cone collapsed. A few hours as magma found a new path to the surface, the ground cracked in nearby Nāpau Crater, lava fountains lit up the night sky. However, activity in this area was short-lived, the center of activity soon shifted back to Puʻu ʻŌʻō; as of January 2007, 3.1 cubic km of lava had covered 117 km2 and added 201 hectares to Kīlauea's southern shore. The new shoreline was 15.6 km long.

The lava flows have destroyed 189 structures and covered 14 km of highway with as much as 35 m of lava. In 2007, after a cluster of earthquakes, activity in Puʻu ʻŌʻō subsided and the crater floor collapsed, with no incandescence visible in the crater after the end of August. Lava began emerging from a series of cracks in the northeast rift zone and spread east and south as a perched flow, with slow advances of ʻaʻā; the flow spread over flows of 1983–1986, with minor incursions into adjoining forests. In late July 2008, additional flows extended from the eastern vents of Puʻu ʻŌʻō and in October multiple new fissures opened along the length of the tube expanding into Royal Gardens Subdivision and covered a large area of the coastal flats in November 2008. On March 5, 2011, the floor of the Puʻu ʻŌʻō crater deflated collapsed. Two hours a new eruption occurred in Kīlauea's middle east zone, between Puʻu ʻŌʻō and Napau Crater. Lava fountains were reported to be 65 feet high. On March 26, 2011, lava began being visible in USGS HVO webcam.

The USGS stated that the accumulation of lava had put the crater floor about 39 m below the eastern crater rim, as of June 1. On September 21, 2011, lava in the west lava lake in Puʻu ʻŌʻō Crater fed a series of lava flows that traveled down the west flank of Puʻu ʻŌʻō during September 20–
