Purdue professor: Mauna Loa lava flows could threaten populated areas
12-02-2022
INDIANAPOLIS (WISH) — Lava flows from the Mauna Loa volcano on the island of Hawaii could threaten people living there, according to a professor from Purdue University. Mauna Loa, one of the five volcanoes that form the island of Hawaii — also called the “Big Island” — erupted on Sunday for the first time since 1984 and has been shooting lava fountains of magma up to 100 feet in the air. Dr. Jonathan Delph, an assistant professor of seismology at Purdue’s department of Earth, atmospheric, and planetary sciences, says the biggest threat to the island of Hawaii is lava flows reaching homes and businesses.

A toxin which makes pigs vomit is the surprising key which has unlocked the century-old mystery of the origins of a Martian meteorite, and the possible identity of the Black student who discovered it. In 1931, an unusual stone stored in the geological collection of Purdue University in the USA was identified as a pristine example of a meteorite – a piece of space rock blasted from the surface of Mars millions of years ago before being pulled into the Earth’s atmosphere. Dr. Marissa Tremblay is a co-author of this work.
