The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is capable of producing 9.0+ magnitude earthquakes and tsunamis that could reach 30 m (98 ft). The Oregon Department of Emergency Management estimates shaking would last 5–7 minutes along the coast, with strength and intensity decreasing further from the epicenter. It is a very long, sloping subduction zone where the Explorer, Juan de Fuca, and Gorda plates move to the east and slide below the much larger mostly continental North American plate. The zone varies in width and lies offshore beginning near Cape Mendocino, Northern California, passing through Oregon and Washington, and terminating at about Vancouver Island in British Columbia.
The Awash River is a major river of Ethiopia. Its course is entirely contained within the boundaries of Ethiopia and empties into a chain of interconnected lakes that begin with Lake Gargori and end with Lake Abbe on the border with Djibouti, some 100 kilometres from the head of the Gulf of Tadjoura. The Awash River is the principal stream of an endorheic drainage basin covering parts of the Amhara, Oromia and Somali Regions, as well as the southern half of the Afar Region. The Awash River basin, spanning 23 administrative zones, covers 10% of Ethiopia's area.

The 2011 Nabro eruption was an eruption of the Nabro stratovolcano in the Southern Red Sea Region of Eritrea, which began on 12 June 2011 after a series of earthquakes. The eruption killed seven and possibly a further 31 people and is estimated to be the highest altitude injection of sulfur dioxide (SO2) ever observed by satellite. The Mount Pinatubo eruption 20 years earlier emitted ten times more SO2. The ash cloud from the eruption reached altitudes which disrupted airline traffic in the region. Until the eruption began, the volcano had no records of historical eruptions.
Char char is one of the Aanaas in the Oromia Region of Ethiopia. It is part of the West Hararghe Zone. It was separated from Guba Koricha Aanaa.
Kone is a volcano located in the Oromia region of Ethiopia. It is located on the Main Ethiopian Rift, which belongs to the most northern branch of the East African Rift Valley. Borchotto, the nearest town to Kone, is 5 kilometers away, and the capital of Ethiopia, Addis Ababa, is situated 160 kilometers to the west. The nearest volcano is Mount Fentale located 30 kilometers to the northwest, with the Boseti Gudo Volcano further away to the southeast. Kone takes up an area of about 647.5 square kilometers and has an elevation of 1619 meters.
The 1993 Klamath Falls earthquakes took place in Klamath Falls, Oregon, beginning on Monday, September 20 at 8:28 p.m. The doublet earthquake registered respective magnitudes of 6.0 and 5.9 on the moment magnitude scale. The earthquakes were located at a depth of 5.6 miles (9 km) and tremors continued to be felt more than three months after the initial shocks.
At 02:10 PM local time (UTC-5) on 28 January 2020, an earthquake with a magnitude of 7.7 struck the north side of the Cayman Trough, north of Jamaica and west of the southern tip of Cuba, with the epicenter being 80 miles (130 km) east-southeast of Cayman Brac, Cayman Islands, and 83 miles (134 km) north of Montego Bay, Jamaica. Schools in Jamaica, as well as corporate and public buildings in Miami, were evacuated after shaking was experienced in parts of the U.S. state of Florida, a region not typically thought of in-relation to seismic activity. Light shaking was also reported on the Yucatán Peninsula in Mexico. The quake was the largest seismic event in the Caribbean since 1946. A tsunami warning for the Caribbean Sea was initially issued by the Pacific Tsunami Warning Center, later being withdrawn.
The 1969 Sardo earthquakes, which occurred from March 29, 1969 to April 05, 1969 was an earthquake swarm of three events with magnitudes of 6.2 and 6.1 Mw in the Afar Region, Ethiopia. All three tremors had estimated intensities of between IX (Violent) and VIII (Severe) respectively. It killed a total of about 20–40 people and further injuring 160 as well.
The following is a list of events predicted and scheduled to take place in the year 2024 in Ethiopia.

Dofan or Dofen is a 1,151 m (3,776 ft) high rhyolitic shield volcano in Ethiopia's Awash National Park. The volcano rises 450 m (1,480 ft) above the valley floor. A north–south zone of cinder cones extending 10 km (6.2 mi); the cones in the north show intense fumarolic activity. Along the southern flank crater, a fumarole produced significant sulfur. The volcano's last eruptions were during the Holocene. On 2 January 2025, smoke emitted from the volcano, prompting tens of thousands of residents living in the area to evacuate. The Ethiopian Geological Institute reported steam and debris expelled from the volcano. However, the Ethiopian Disaster Risk Management Commission did not confirm the eruption. The activity comes amid an earthquake swarm that lasted several weeks.
