“In memory of” is highlighting deadly earthquakes of the past.
People have forgotten a lot of these human tragedies.
We @ Earthquake Report are hopeful that people in these countries and cities will learn from their history and will make sure that they are building Earthquake Proof houses and that they know what to do when the earth will be shaking again.


M 7.3 – 18-08-59 – Depth 15 km –
United States – killing 28 people
This earthquake caused 28 fatalities and about $11 million in damage to highways and timber.
The most spectacular and disastrous effect of the earthquake was the huge avalanche of rock, soil and trees that cascaded from the steep south wall of the Madison River Canyon. This slide formed a barrier that blocked the gorge and stopped the flow of the Madison River and, within a few weeks, created a lake almost 53 meters deep. The volume of material that blocked the Madison River below Hebgen Dam has been estimated at 28 – 33 million cubic meters. Most of the 28 deaths were caused by rockslides that covered the Rock Creek public campground on the Madison River, about 9.5 kilometers below Hebgen Dam.
On the basis of vibration damage (and excluding geologic effects), damage to buildings along the fault zone was singularly unspectacular (MM intensity VIII at places, intensity VII generally). Minor damage occurred throughout southern Montana, northeast Idaho, and northwest Wyoming. Felt as far as Seattle, Washington, to the west; Banff, Canada, to the north; Dickinson, North Dakota, to the east; and Provo, Utah, to the south. This area includes nine Western States and three Canadian Provinces. Aftershocks continued for several months.

M 5.9 – 18-08-80 – Depth 56 km – Ecuador – killing 8 people
Eight people killed, 100 injured and extensive damage in the Guayaquil area.

M 5.8 – 18-08-94 – Depth 9 km – Algeria – killing 171 people
At least 159 people were killed, 289 injured, 8,000 to 10,000 left homeless and thousands of mud-brick houses destroyed in Mascara Province.
