Tanzania Earthquake Sends Tremors Across Parts of Kenya

Parts of Kenya experienced ground shaking on Thursday, November 5, 2026, following an earthquake recorded in the Lake Victoria region of neighbouring Tanzania.

The tremor was reportedly felt in several locations, with some residents noticing buildings and other structures briefly shaking. However, the intensity of the movement varied across different areas, while some people reported that they did not feel anything.

According to the Euro-Mediterranean Seismological Centre (EMSC), the earthquake registered a magnitude of 5.1 and occurred at approximately 12:22pm local time.

The seismic event was recorded at a depth of about 10 kilometres beneath the Earth’s surface. Its epicentre was located at latitude -3.424 and longitude 32.191, approximately 128 kilometres south-southwest of Mwanza and 26 kilometres east-northeast of Ushirombo in Tanzania.

The earthquake’s effects extended beyond Tanzania, with reports of ground movement emerging from parts of Kenya.

Why Kenya Felt the Tremor

University of Nairobi Chairperson of Earth and Climate Sciences Professor Maina Gichaba explained that Kenya has a network of seismographs used to monitor seismic activity within the country and neighbouring regions.

He noted that earthquakes and smaller tremors occur regularly in the region, although many pass unnoticed because of their relatively low magnitude.

According to Gichaba, whether people experience ground shaking depends on several factors, including the strength of the earthquake and the distance between the affected location and the epicentre.

He explained that seismic activity exceeding a magnitude of approximately 4.2 may become noticeable, although the level of shaking can reduce considerably as the distance from the source increases.

In Thursday’s incident, the distance between the Tanzanian epicentre and Kenyan locations reduced the intensity of the ground movement experienced locally.

Kenya’s Earthquake Monitoring Capacity

Gichaba said Kenya has several seismic monitoring stations capable of recording underground movements and providing information about earthquakes.

However, he acknowledged that the country still faces challenges in fully utilising its available monitoring equipment.

He revealed that some equipment acquired for seismic monitoring had not been installed because of various challenges, limiting the country’s ability to maximise its monitoring infrastructure.

The professor said efforts were underway to revive the equipment and improve coordination between monitoring stations.

A functional monitoring network would enable experts to establish the location, magnitude and depth of earthquakes more efficiently while analysing how seismic waves move through the region.

Rift Valley Among Areas of Geological Activity

Gichaba also pointed to the geological characteristics of the Great Rift Valley, describing it as an active region with extensive underground fractures and geothermal activity.

He explained that movements along geological faults, cracks and other structures beneath the Earth’s surface can release energy, producing seismic waves that travel through the ground.

Such movements are part of the natural geological processes occurring across the East African region.

The professor emphasised the importance of strengthening Kenya’s earthquake monitoring systems to improve the country’s ability to detect and analyse seismic events.

Although Thursday’s earthquake originated in Tanzania, its effects demonstrated how seismic activity in one country can be experienced across international borders.

Kenya’s continued investment in monitoring infrastructure would therefore be important in improving the understanding of earthquakes and their potential effects on communities.
