US newlyweds Lauren and Matt Urey were on their honeymoon. Lauren's mother, Barbara Barham, told the Washington Post the couple from Virginia had plans to visit a live volcano and were not concerned about possible eruptions.
Matt, 36, left his mother a voicemail message saying they had been "burned very bad".
"He said he would try to call as soon as he could, but talking and making phone calls was difficult," Ms Barham said of the message that Matt's mother relayed to her.
"His hands were so badly burned it was hard for him to make a phone call."
Matt's mother, Janet, revealed he underwent three hours of surgery but was now able to talk, take in fluids and eat jelly. However, Lauren, 32, who is in a different hospital, was still sedated on Tuesday.
She revealed the couple, who were wearing respirators at the time of the explosion, had taken shelter "behind a large rock".
"Ten minutes... could have meant life or death for them, but luckily they were already down the volcano close to the water, so they sheltered themselves a little bit," she told local news channel 21WFMJ.
