2006 Earthquakes

On 10/15/2006, two earthquakes (epicenters at Kīholo Bay and Mahukona) with magnitudes of 6.7 and 6.0 caused extensive damage at many locations, particularly the northern half of the Big Island.

Crumbled front walls of the Kohala Congregational Church
The Congregational Church in Kohala was severely damaged. Fortunately, the Sunday earthquakes occurred in the early morning, before services.

Cracks appeared in many roads, such as this one on the road to Pololū Valley. Government road crews quickly assessed the situation.

Damaged acoustic roof tiles strewn about a classroom
The Waikoloa Elementary School had many ceiling tiles and light fixtures fall. It's obvious that “drop, cover and hold” under a desk would protect you from falling debris.
Broken glassware on a kitchen counter
Many fragile items broke when they fell from shelves.
Damaged rock walls with fallen rocks nearby
Rock walls were damaged.
Mirrored closet doors off of their track
Mirrored closet doors fell over.
Cans and bottles piled on the ground
Cans and bottles were thrown from shelves.
Beverages (wine bottles, Dr Pepper cans) strewn on the floor at a convenience store
At the Waikoloa Highlands Chevron, the earthquakes shook merchandise from shelves.
A pile of dvds from a fallen shelf
Items tend to fall off shelves during large earthquakes. A simple piece of wood or wire across the front of each shelf can prevent this. L-shaped brackets can secure bookshelves to the wall.
Aisle at a convenience store filled with fallen grocery items, beverages
Many stores, such as Takata’s in Hawi, had to clean up after the earthquake.
Bottles spilled on the floor of a service station
Notice the preferential direction of breakage at the Chevron, which parallels the direction of the fault.
Broken wineglasses on a kitchen counter
Many residents lost wineglasses in the earthquake. Glassware is far less likely to slide off a shelf if there is a lip of wood across the front. A lip is easy to install.

The smokestack of the Hawi sugar mill collapsed during the earthquake.

1999 Pāhala Earthquake

On 4/22/1999, Pāhala experienced an earthquake of magnitude 5.6, which caused damage near the epicenter. (The 1868 earthquake, which was the largest in recorded Hawaiʻi history, occurred in the same area; its magnitude is estimated to be 7.9.)
