Geologic Events

What are geologic events?

Geologic events are any natural occurrences that change how the Earth looks. They include things like volcanoes (vòlkan), earthquakes (tranbleman tè), tsunamis, and erosion (ewozyon). Think of this like Earth's own "remodeling". Scientists understand these events to understand how our planet changes.

Haiti Earthquake - 2010

The 2010 Haiti earthquake was a very strong earthquake that hit Haiti on January 12, 2010. About three million people were affected by the earthquake, many homes were destroyed. The 2010 Haiti earthquake was a 7.0 magnitude earthquake. The focus of the earthquake was 6.2 miles below the surface of the Earth. Because of its shallow depth the earthquake had a devastating effect on the country.

Mauna Loa Eruptions

The world’s largest volcano is Mauna Loa. It is located on the south-central part of the island of Hawaii, in the U.S. state of Hawaii. Mauna Loa is highly active. It has erupted 34 times since 1843. After remaining quiet for nearly four decades, Mauna Loa began erupting again in late November 2022.

Indonesia Tsunami - 2018

In 2018, Indonesia experienced a series of significant earthquakes, including six that measured a magnitude of 6.0 or greater. On September 28, 2018, a powerful 7.4 magnitude earthquake struck the central province of Sulawesi, Indonesia, triggering a destructive tsunami with waves reaching approximately 20 feet in height. On December 22, 2018, undersea landslides triggered another tsunami in the Sunda Strait between Indonesia’s Java and Sumatra islands.
