In the past month, a series of tremors has captured the attention of residents and geologists alike. Understanding these seismic shifts is not just a matter of scientific curiosity; it is an essential part of living safely in the shadow of an active volcano. More Latest Earthquakes and Safety Guide: Phivolcs

The Latest Data: A Month of Movement
According to the latest tracking data from VolcanoDiscovery, the region surrounding Mt. Cabalian has experienced a noticeable uptick in seismic activity. In the past 30 days, the area near the volcano has recorded a total of 16 earthquakes.

The breakdown of these events gives us a clearer picture of the regional energy being released:

2 quakes above magnitude 4: These are the events that grab headlines, often felt by residents as a distinct swaying or jolt.

2 quakes between magnitude 3 and 4: These moderate tremors are generally felt by people indoors but rarely cause structural damage.

7 quakes between magnitude 2 and 3: These are light tremors, often felt only by those who are still or in high-rise buildings.

5 quakes below magnitude 2: These are “micro-quakes,” detected only by sensitive seismographs and usually go unnoticed by the public.

Narrowing the window further, the past 7 days alone have seen 8 quakes, with magnitudes reaching up to 4.1. While these numbers might seem alarming, it is important to place them in the context of Southern Leyte’s unique geological location.

Tectonic vs. Volcanic: What is Happening?
When we see a cluster of earthquakes near a volcano, the immediate question is: Is it about to erupt? In the case of Mt. Cabalian, the answer requires looking at the Philippine Fault Zone. Southern Leyte sits atop one of the most active fault lines in the world. Most of the 16 quakes recorded this month are likely tectonic in nature—caused by the shifting of the earth’s crust rather than the movement of magma.

However, because Mt. Cabalian is an active volcano, PHIVOLCS (the Philippine Institute of Volcanology and Seismology) monitors these tremors closely. Volcanic earthquakes are typically shallower and occur in “swarms.” For now, the tremors remain within the expected background activity for a tectonically active province, but they serve as a “wake-up call” for disaster consciousness.

The History of the “Sleeping Giant”
Mt. Cabalian is not just a mountain; it is a stratovolcano with a history of power. Its last major eruption is estimated to have occurred in the 1820s. Since then, it has been in a state of “rest,” but “rest” in volcanic terms does not mean “dead.”

The presence of the Mainit Hot Springs on its slopes and the geothermal heat that keeps the waters of Lake Danao unique are proof that the volcano’s internal plumbing is still warm. History shows us that volcanoes can remain quiet for centuries before entering a new cycle of activity. Journalistic records from the region emphasize that being prepared is the best way to honor the mountain’s power without living in fear.

Essential Preparation: The Volcano Safety Guide
With 16 quakes in 30 days, now is the perfect time to review your family’s emergency readiness. Preparation is the bridge between panic and peace of mind.

Latest Earthquakes and Safety Guide

1. The Emergency “Go-Bag”
Every household in San Juan, Anahawan, and surrounding areas should have a bag packed and ready. Volcanic emergencies can happen quickly, and ashfall can happen even faster.

Respiratory Protection: N95 masks are essential. Volcanic ash is composed of tiny jagged pieces of rock and glass; breathing it in can cause permanent lung damage.

Eye Protection: Pack goggles. Ash can scratch the cornea of the eye, making it difficult to evacuate.

Communication: A battery-powered radio. In a major seismic event, cellular networks often fail. Local radio stations will be your primary source of official LGU updates.

2. Identifying “Signs of Unrest”
While we rely on PHIVOLCS for technical data, locals can be the “eyes and ears” on the ground. Watch for these natural signs:

Changes in Lake Danao: If the water suddenly changes color, starts bubbling, or the water level drops/rises rapidly without rain, report it.

Vegetation Stress: A sudden “wilting” or browning of trees on the upper slopes can indicate that volcanic gases are leaking through the soil or that the ground temperature is rising.

Smell: A strong scent of sulfur (rotten eggs) where it wasn’t present before is a classic sign of volcanic gas emission.

3. Structural Awareness
During the recent 4.1 magnitude quakes, many residents noticed small cracks in old masonry. Check your home for structural integrity. Secure heavy furniture (like bookshelves or cabinets) to the walls to prevent them from falling during a tremor.

The Role of Lake Danao in Monitoring
Lake Danao is more than a beautiful photo opportunity; it is a “window” into the volcano. Because the lake sits directly in the crater, its chemistry and temperature are vital indicators of what is happening beneath the summit. In recent journalistic reports, the lake has remained stable, but the frequency of quakes in the last 7 days means that monitoring these waters is more critical than ever.

A Community of Resilience
Living near Mt. Cabalian is a gift. It provides the province with fertile soil, beautiful landscapes, and a sense of identity. However, that gift comes with the responsibility of being an informed citizen.

The 16 earthquakes over the last month are a reminder from nature. They tell us that we live on a dynamic, changing planet. By staying updated with data from sources like VolcanoDiscovery and PHIVOLCS, and by ensuring our families are prepared, we can continue to live in harmony with the “Sleeping Giant” of Southern Leyte.
