The 1985 Nahanni earthquakes is the name for a continuous sequence of earthquakes that began in 1985 in the Nahanni region of the Northwest Territories, Canada.[2] The largest of these earthquakes occurred on December 23, reaching 6.9 on the moment magnitude scale.[2] This is one of the most significant earthquakes in Canada during the 20th century.[3] The earthquakes had a long succession of aftershocks and jolts.[2] The earthquakes amazed both the general public and the earth science community and have been felt in the Yukon, Alberta, Saskatchewan, British Columbia, and southeastern Alaska.[2]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
