Three Ways To Survive a Tsunami

The tsunami associated with Hunga Tonga eruption has sparked renewed interest in hazards associated with earthquakes, volcanoes, and tsunamis. A recent article about geologic hazards and preparedness especially caught my attention: “A Tsunami Could Kill Thousands. Is Escape Possible?” in the New York Times. The focus is on the Pacific Northwest- –specifically coastal communities along the states of Washington, Oregon, and northernmost California.

Tsunami Troubles

Large earthquakes, volcanic eruptions, and tsunamis can create shock waves felt around the world – literally. The blast from the volcanic eruption on January 15, 2022, near Tonga caused spikes in air pressure recorded around the planet. We can add this eruption in a remote part of the Pacific Ocean to our knowledge of pandemics, climate change, and numerous other interconnections that tie our planet and our societies together.

Iceland’s Volcanic Theater

Iceland is a fabulous showcase for volcanoes. The easily accessible locations to view explosions of fiery lava and ash provide unusual opportunities for volcano-appreciators of all types, giving them ringside seats for the action. In the past few decades, there have been several spectacular volcanic performances. Attempting to control volcanoes is a major challenge, although people have tried, and even achieved success.

Volcanoes and East African Rift Roulette

The volcano recently erupting in Africa–Mount Nyiragongo–is one of the most active on our planet. Eruptions in 1977, 2002 and now beginning in May 2021, have resulted in a significant number of fatalities and extensive damage in the nearby and densely populated city of Goma. If scientists were calling the shots, they would relocate Goma and designate the region beneath this active volcano as a national park.

A Few Facts: Volcanic Explosions

Volcano-watchers have had lots of excitement lately with the ongoing eruptions on the Reykjavik Peninsula in Iceland and Soufriere, on the West Indies island of Saint Vincent. So far both eruptions are fairly small. Colorful graphic representations of the relative sizes of volcanic eruptions are intriguing, although variability in natural events confounds human attempts to assign neat boxes or bubbles to these phenomena.

Kilauea Stirring

On the evening of Dec 20, 2020, an eerie orange glow appeared on the infrared monitoring cameras on the summit of Kilauea volcano in Hawai’i Volcanoes National Park. The glow grew larger and larger, marking the beginning of a new volcanic eruption. Lava began pouring out from fissures in the summit crater and a steam cloud developed as the hot lava hit lake water and the water began to boil.
