See privacy policy.It’s been a month since Hawaii’s Kilauea volcano first erupted, but it’s consequences remain. Lava flows are showing no signs of relenting and there are still dangers of vog (volcanic gas) and Pele’s hair (thin strands of volcanic glass).The thousands of displaced residents are not the only ones affected by the eruption — it’s also taken a toll on tourism to Hawaii’s Big Island. Although the eruption is localized to an area where very few tourists venture, Hawaiian Airlines and Hilton both said on Monday that they’ve experienced a decline in bookings since news broke of the volcanic activity.No flights have been canceled or delayed yet as a result of the eruption, but with the USGS’ warnings of additional outbreaks of lava, many airlines have further extended their travel waivers in Hawaii.
