measured at VII on the Mercalli intensity scale. There were only two recorded casualties, one of which involved a motorist who was crushed in a rock slide on U.S. Route 97. The second death was a result of a heart attack. The tremors precipitated landslides and also caused structural damage to buildings, including the county courthouse, in addition to private residences, businesses and historic buildings in Klamath Falls. Damage was estimated at approximately $10 million. Aftermath In the wake of the earthquakes, several damaged buildings in Klamath Falls and elsewhere in Klamath County had to be repaired. The city of Klamath Falls obtained a Community Development Block Grant which was used to partially fund upgrades to local public buildings, including the courthouse annex. Within three weeks after the first major shocks four seismographs were installed in the area by the U.S. Geological Survey. These were helpful in recording subsequent seismic activity.
