Executive Summary for the Earthquake in Sabah
A magnitude 6.8 earthquake occurred offshore Sabah on 23 February. Initial reports indicate no widespread structural collapse or mass casualties; however, localized landslides, infrastructure inspections, and short-term utility disruption remain plausible, particularly in flood-affected northern districts.
- Event Date: 23 February
- Location: Sabah, Malaysia
- Risk Category: Natural Disasters
- Severity Level: 3 / 5
- Confidence Score: 70 %
Operational Context
On 23 February, a magnitude 6.8 earthquake was recorded offshore Sabah. Offshore epicentres of this magnitude typically reduce catastrophic structural collapse risk inland but increase exposure to secondary hazards including landslides, slope instability, localized liquefaction, and coastal infrastructure stress. Northern Sabah districts such as Kota Marudu, Pitas, Kudat, and Paitan remain sensitive due to antecedent flooding, which may have weakened soil cohesion and increased vulnerability of slopes, shallow foundations, and road embankments. The primary impact window is the first 24–72 hours, during which moderate aftershocks and structural inspections drive operational uncertainty. Residual aftershock risk may persist for up to two weeks.
Known Hotspots & Sensitive Zones
- High-impact zones: Coastal and low-lying settlements in Kota Marudu, Pitas, Kudat, and Paitan; small port facilities and wharves; hill-slope roads vulnerable to ground movement.
- Medium-impact areas: Provincial connectors including Jalan Kudat–Kota Marudu and coastal access roads subject to inspection closures.
- Low-impact areas: Inland urban centres outside the 0–200 km coastal band, where shaking intensity is expected to be moderate.
Northern Sabah has experienced recurrent minor seismic events in recent years, with heightened landslide risk when combined with heavy rainfall.
Impact on Transportation & Services
Short-term transport disruption is possible due to precautionary inspections of bridges and slope-adjacent roads. Temporary suspension of inter-district bus routes and freight movement to northern ports may occur pending structural assessments. Nearshore fishing and ferry services could face brief operational pauses. Localized power outages and water supply interruptions are plausible in saturated coastal zones where distribution infrastructure is shallow. Telecommunications may experience intermittent disruption at individual cell sites, though national backbone systems are expected to remain intact. For businesses, operational impacts are likely limited to 24–72 hours of logistics rerouting, facility inspections, and workforce accountability checks.
Recommended Action
- Organizations should activate emergency response and staff accountability protocols immediately, confirming personnel safety within two hours of notification.
- Conduct rapid structural checks before re-entry to facilities and isolate damaged utilities.
- Prioritize inspection of fuel storage, generators, and critical equipment.
- Logistics operators should identify alternate routing options and prepare contingency warehousing outside affected districts.
- IT teams should confirm cloud backup integrity and remote access capability to sustain business continuity.
- Coordinate with local disaster management authorities, municipal councils, and maritime regulators regarding inspection requirements and reporting obligations.
Multi-Dimensional Impact
The earthquake may slow ongoing flood recovery operations in northern Sabah by diverting inspection teams and emergency resources, potentially extending infrastructure repair timelines by several days.

Situational Outlook
The most probable scenario involves moderate aftershocks over the next 24–72 hours, localized infrastructure inspections, and restoration of minor utility outages within two days. A moderate escalation could emerge if clustered aftershocks up to magnitude 5.5 trigger slope failures or bridge damage, causing multi-day road closures and short-term port suspensions. Severe escalation remains low probability but could result from a significant aftershock exceeding magnitude 6.0, potentially extending displacement, transport corridor closures, and supply chain disruption across northern Sabah for one week or longer. Current indicators support contained but operationally sensitive disruption requiring close monitoring through the next 14 days.
Strategic Takeaway
The offshore earthquake presents a manageable but dynamic natural disaster risk for Sabah. While catastrophic structural collapse appears unlikely, secondary hazards such as landslides, aftershocks, and infrastructure inspections may disrupt transport and utilities in vulnerable coastal districts. Businesses should emphasize rapid safety verification, contingency logistics planning, and structured communication.
