input question: Given the following context:  In the years following the eruption, despite earning rapid fame and opportunities to research internationally in Japan, New Zealand, and Guadeloupe, Glicken still failed to obtain a job at USGS. Senior employees at the Survey found his behavioral oddities unsettling. Activity at Mount St. Helens diminished, prompting USGS to reduce CVO's budget and contemplate closing the station. He continued helping the Survey until 1989, also serving as an assistant researcher at the University of California at Santa Barbara.From 1989 to 1991, Glicken continued his volcanological studies in Japan as a postdoctoral fellow at the Earthquake Research Institute of the University of Tokyo, supported by grants from the U.S. National Science Foundation. Later, while a research professor and translator at Tokyo Metropolitan University, Glicken became involved with research at Mount Unzen. The volcano had recently resumed eruptive activity in November 1990, after being dormant for 198 years. In the months after its first activity, it erupted sporadically, and the government evacuated its vicinity near the end of May 1991. On June 2, 1991, Glicken visited the mountain with Katia and Maurice Krafft. The three entered a danger zone near the base of the volcano the following day, assuming that any potentially hazardous pyroclastic flows would follow a turn in the landscape and safely bypass them. Later that day, a lava dome collapsed, sending a large flow down the valley at 60 miles per hour (97 km/h). The current reached the turn before separating into two parts, and the upper, hotter part swiftly overcame the volcanologists' post, killing them upon impact. In total, 41 or 42 people died in the incident, including press members who had been watching the volcanologists. The volcano burned down 390 houses, and the remains of the flow extended 2.5 miles (4 km) in length. Glicken's remains were found four days later, and were cremated according to his parents' wishes. To date, Glicken and Johnston are the only American volcanologists...  answer the following question:  What is the last name of the American volcanologist that has died along with the man continued his volcanological studies in Japan????
output answer: Johnston

It was released worldwide on September 7, 2007, as the fourth single of the album.

Problem: Given the question: Given the following context:  Opeth recorded its debut album, Orchid, with producer Dan Swanö in April 1994. Because of distribution problems with the newly formed Candlelight Records, the album was not released until May 15, 1995, and only in Europe. Orchid tested the boundaries of traditional death metal, featuring acoustic guitars, piano, and clean vocals.After a few live shows in the United Kingdom, Opeth returned to the studio in March 1996 to begin work on a second album, again produced by Dan Swanö. The album was named Morningrise, and was released in Europe on June 24, 1996. With only five songs, but lasting 66 minutes, it features Opeth's longest song, the twenty-minute "Black Rose Immortal". Opeth toured the UK in support of Morningrise, followed by a 26-date Scandinavian tour with Cradle of Filth. While on tour, Opeth attracted the attention of Century Media Records, who signed the band and released the first two albums in the United States in 1997.In 1997, after the tour, Åkerfeldt and Lindgren dismissed De Farfalla for personal reasons, without the consent of Nordin. When Åkerfeldt informed Nordin, who was on a vacation in Brazil, Nordin left the band and remained in Brazil for personal reasons. Former Eternal members, drummer Martín López (formerly of Amon Amarth) and bassist Martín Méndez, responded to an ad at a music shop placed by Åkerfeldt. López and Méndez were fans of the band and took the ads down themselves so no other musicians could apply for the job. Åkerfeldt and Lindgren did not want the Martíns to join at first, due to them already knowing each other; they felt that they wanted two strangers so that there wouldn't be two camps in the band, but eventually hired both. López made his debut with Opeth playing on a cover version of Iron Maiden's "Remember Tomorrow", which was included on the album A Call to Irons: A Tribute to Iron Maiden.With a larger recording budget from Century Media, Opeth began work on its third album, with noted Swedish producer Fredrik Nordström, at Studio Fredman in August 1997. Although...  answer the following question:  What is the last name of the person whose departure from the band caused another band member to leave?
