Yes, it's true. The erupting volcano is Kilauea. If you put that name into your search engine you should be able to find some interesting info. Mauna Kea and Mauna Loa are the biggest on the island, dormant and active, respectively. When this current eruption started there were spectacular fountains of lava; now it's settled down to a more or less steady flow of lava through underground tubes several miles in length and emptying into the sea. Sometimes at night from our living room window we can see an orange glow in the sky which is a reflection in the steam clouds of the lava lake inside the most active cone.
And yes, Hawaii is expanding. All the Hawaiian islands arose from volcanoes. The Big Island of Hawaii is the youngest and largest; it's still expanding and hasn't started eroding that much. The whole island chain extends in a northwesterly direction out to Midway Island and Kure Atoll, because the Pacific plate is traveling in that direction over a stationary hot spot. Iceland is another "hot spot" volcanic island. The "next" Hawaiian island is an undersea volcano called Loihi, just off the southeast coast of our island.
Aren't you glad you asked?
