World Tsunami Awareness Day – 5 November

Every year on November 5th, countries around the world observe World Tsunami Awareness Day. This day raises tsunami awareness and shares innovative approaches to risk reduction.

Tsunamis are rare, but when they do occur, they can be very destructive. Tsunamis are considered one of the deadliest types of natural disasters. The Indian Ocean tsunami in 2004 claimed 227,000 lives in 14 countries. In the last 100 years, 58 tsunamis have caused more than 260,000 lives. Tsunamis are most common in the Pacific Ocean and Indonesia. However, many other countries are at a high risk of experiencing tsunamis. These countries include:

  • Chile and Peru
  • West Coast of the United States
  • Japan
  • New Zealand
  • India
  • Italy
  • Morocco
  • Portugal

An earthquake must occur before a tsunami. It’s the seismic activity from an earthquake that causes a series of eruptions in the ocean waters. These eruptions become giant waves. When these waves travel inland, they build up to higher and higher heights. The highest tsunami wave ever recorded was 100 feet high. This occurred in Alaska’s Lituya Bay in 1958. Because this area is sparsely populated, only five deaths were recorded. Besides achieving great heights, waves from tsunamis also travel quickly. During the Indian Ocean tsunami, the waves traveled 500 miles per hour.

Once a person has survived the earthquake preceding the tsunami, they must also survive the tidal wave that hits, and then the flooding that follows. When a tsunami warning is issued, it’s imperative to get to high ground or as far inland as possible.

Endangered Species Day – 11 May

We live in a world full of many animals, insects, plants and creatures which are approaching risk of extinction – or are so close to extinction, that their species needs help immediately. When a species is defined as endangered, its numbers are especially low – in the last few thousands, hundreds, or even tens. And when the last of the species is gone, they are gone for good.

This day was created to keep us aware of how fragile the existence of some animals, plants, and insects is – and, most importantly, reminds us to take the time to learn about why it’s so important to protect endangered species from any further harm.

The History of Endangered Species Day
Since time began, there have been endangered species. Perhaps one of the earliest and most learned about extinctions in history is that of the dinosaurs. However, an endangered species is one which is still in the world today, but may not be much longer if the right steps aren’t taken.

The status of ‘endangered’ is decided by the International Union for Conversation of Nature. According to the IUCN, at least 40% of animal, insect and plant species across the world are at risk of extinction. Some ways of helping endangered species have included captive breeding, which sees endangered or rare species in captivity encouraged to breed in an effort to improve their numbers in the wild.

Reasons for endangerment are varied – this may be down to environmental changes, over-hunting by predators, poaching, the changing or destruction of habits by humans or natural disasters to name a few.
