PHIVOLCS warning now on Social Media in preparation for the BIG ONE

Handa na ba tayo sa "The Big One"? The last time an earthquake occurred along the West Valley fault was in 1658, around 355 years ago. -Photo credits to the owner
In relation with the previous blog that we had about the "Big One" and now as well know that we are experiencing frequent earthquakes for the past weeks. Is this a sign that a huge earthquake is coming?

Why earthquakes is happening?

Remember the biggest earthquake that the Philippines has experienced? Yeah! You're right the 1991 earthquake in Baguio were enormous distractions occurred in the said province. As far as I can remember, I was 7 years old when this news came up on local televisions. 

So, what really happened that time. 

The 1990 Luzon earthquake occurred on July 16 at 4:26 p.m. 3:26 pm Local time on the densely populated island of Luzon in the Philippines. The shock had a surface wave magnitude of 7.8 and produced a 125 km-long ground rupture that stretched from Dingalan, Aurora to Cuyapo, Nueva Ecija. The event was a result of strike-slip movements along the Philippine Fault and the Digdig Fault within the Philippine Fault System. The earthquake's epicenter was near the town of Rizal, Nueva Ecija, northeast of Cabanatuan City. An estimated 1,621 people were killed, most of the fatalities located in Central Luzon and the Cordillera region.

The earthquake caused damage within an area of about 20,000 square kilometers, stretching from the mountains of the Cordillera Administrative Region and through the Central Luzon region. The earthquake was strongly felt in Metropolitan Manila, destroying many buildings and leading to panic and stampedes and ultimately three deaths in the National Capital Region, one of the lowest fatalities recorded in the wake of the tremor. The Southern Tagalog (nowadays Regions 4A and 4B) and Bicol Regions also felt the quake, but with low casualty figures.

The Hyatt Terraces Hotel was a 12-storey hotel in Baguio, Philippines. It sustained the most serious damage among other building in Baguio following the 1990 Luzon earthquake when the hotel's terrace front collapse and fell into the lobby area killing at least 50 people.
Based on preliminary analysis, cases and controls were similar in age and sex distribution. Similar proportions of cases and controls were inside and outside buildings during the earthquake. For persons who were inside a building, risk factors included building height, type of building material, and the floor level the person was on. Persons inside buildings with seven or more floors were 35 times more likely to be injured. Persons inside buildings constructed of concrete or mixed materials were three times more likely to sustain injuries than were those inside wooden buildings. 

The earthquake caused different patterns of damage in different parts of Luzon Island. The mountain resort of Baguio was most severely affected, it had a high population density and many tall concrete buildings, which were more susceptible to seismic damage. Relief efforts proved difficult as all routes of communication, roads, and airport access were severed for several days following the quake. These efforts were further hampered by daily rainfall. Baguio is home to a large mining company and a military academy; experienced miners and other disciplined volunteers played a crucial role in early rescue efforts. Rescue teams arriving from Manila and elsewhere in Luzon were able to decrease mortality from major injuries. Surgeons, anesthesiologists, and specialized equipment and supplies were brought to the area, and victims were promptly treated. Patients requiring specialized care not available in the disaster area were airlifted to tertiary hospitals. Damage was caused by landslides in the mountains and settling in coastal areas. Relief efforts in these areas were prompt and successful, partly because those areas remained accessible.

On July 19, three days after the earthquake, the priority of relief efforts shifted from treatment of injuries to public health concerns. For example, numerous broken pipes completely disrupted water systems, limiting the availability of potable water, and refugees who camped in open areas had no adequate toilet facilities. Early efforts at providing potable water by giving refugees chlorine granules were unsuccessful. Most potable water was distributed from fire engines, and Department of Health sanitarians chlorinated the water before it was distributed. Surveys of refugee areas showed few latrines; these had to be dug by the DOH.

An inevitable earthquake which occurred in early April 2017, affecting the Philippine province of Batangas and other nearby areas. The first major earthquake occurred on April 4 at 08:58 PM PST, with a moment magnitude of 5.5 on the coast of Batangas. According to the PHIVOLCS Earthquake Intensity Scale, the earthquake had an intensity of VI (strong).

On April 8, more strong earthquakes occurred in the province. PHIVOLCS recorded the strongest earthquake as having a moment magnitude of 6.0, which occurred in the afternoon. 

Now in social media, people are now getting conscious on this frequent earthquakes and after shocks that normally only happens in Japan.

What to do during earthquakes:

Ensure you do the following if you are outdoors during an earthquake.
Stay there.
Move away from buildings, streetlights, and utility wires.
Once in the open, stay there until the shaking stops. The greatest danger exists directly outside buildings, at exits and alongside exterior walls.

Are we prepared for the BIG ONE?

Prepare Yourself and Your Family to
React Safely. Learn what to do during an earthquake. ...
Take Cover. In each room of your home, identify the safest places to “drop, cover, and hold on” during an earthquake. ...
Survive on Your Own. ...
Stay in Contact. ...
