Scroll to watch how DOit turns a few seconds of warning into safety.
Placed on the ground, middle and top floors, MA301+ sensors measure vibration at 100 samples per second (100 SPS).
EQ-Alarmer receives seismic data from connected sensors and provides on-site status monitoring and configured earthquake alerts. Its screen displays real-time seismic information and alert status.
The P-wave travels faster and arrives first. The S-wave follows with transverse motion and can bring stronger shaking. Surface waves can also cause damage.
Detection starts as the P-wave reaches the sensor. After a short validation and processing interval, EQ-Alarmer issues the local warning without waiting for the S-wave.
EQ-Alarmer activates voice and light alerts. Configured relay and app connections can notify users and trigger protective equipment controls.
Protective action begins before the S-wave in this example. Indoors: drop, cover and hold on. Actual warning time can be very short or unavailable near the source.
The red wavefront reaches the building. Stronger shaking appears on the waveforms while people remain in a protective position. Monitoring continues throughout the event.
Sensors, alarm, software and alerts, delivered as one system by DOit.
Talk to DOitTwo complementary layers of earthquake information, connected through EQ-Alarmer.
Local seismometers detect the arriving P-wave. The system estimates on-site shaking and activates configured alarms and protective controls.
A three-sensor installation can also support building-response monitoring. Structural results support assessment; they are not an automatic occupancy clearance.
National or regional networks provide event information such as origin time, epicenter and magnitude. Some services also estimate shaking and issue early warnings.
Coverage, available fields and delivery time vary by country and service. The two warning paths operate in parallel; either may arrive first.

DOIT / COMPLETE EARTHQUAKE LIFECYCLE
One connected system covers the critical moments before strong shaking, the measurements during the event, and the structural assessment that follows.
MA301+ sensors detect the first arriving P-wave. EQ-Alarmer validates the event, estimates site shaking and issues configured alerts without waiting for the stronger S-wave.
View seismic waveforms as the event unfolds. Monitor connected-sensor status, alarm stages and event timing, with on-site status updates and notifications.
The same synchronized building sensors support post-event structural-response analysis and reporting, giving engineers quantitative information for follow-up assessment.
Structural monitoring results support engineering assessment and decision-making; they are not an automatic building-occupancy clearance.

EQ-ALARM / INTEGRATION & DATA
Seismometer integration modules connect measurement streams with real-time monitoring, storage, transmission and analysis. Reception status, earthquake events and system status remain visible alongside estimated intensity and event reports.
Continuous multi-channel monitoring, digital filters and offset adjustment, MiniSEED event storage and transmission; query, analysis, event status and system management; SHM assessments and event reports.
On-site monitoring, SMS and message services, expected arrival-time monitoring, real-time storage, transmission and analysis, on-site/event/system status and SHM reports.
Three-stage event-trigger alarms, voice and mobile-app notifications, event results and reports. Supported KMA weather and earthquake API information supplements local sensing with estimated site intensity and S-wave arrival information. Broadcast, DCS and related-organization connections are configured per project.
